Buying Guide – How to Choose the Best Portable Projectors?

The portable projector is an excellent solution to be able to bring the emotions of the cinema into your home without spending too much. If you have read our opinions and made a comparison between the offers, you have probably already understood which model is right for you. If not, this short guide will help you distinguish some main features to better orient yourself and buy the portable projector that best suits your needs.

 

Image quality

Portable projectors are often associated with the world of entertainment, in fact there are many users who buy one to complete their home theater system and recreate the cinema experience directly at home. If you love watching movies and playing video games, but your TV screen isn’t enough for you, then we recommend purchasing a projector that supports good native resolution.

It is unlikely that a mini projector will reach native 1080p, a good model must reach at least 720p. This is a good starting resolution that can be scaled to view Full HD and 4K content.

The less expensive products support 480p, with a slightly lower image quality. The quality of the projected image is also defined by the lumens and the LED lamp of the device which contributes to the brightness and color fidelity. A good portable projector can reach up to 200 lumens, ideal for viewing any multimedia content in great detail.

If you are looking for a projector to show work graphics or slides to university students, then you should choose a model that has good focus, as written documents must be clearly legible.

Functions

With the arrival of Wi-Fi and Bluetooth connections, portable projectors have also evolved by integrating functions for connectivity and more. In fact, on the market it will be possible to find models with Wi-Fi connection and Android operating system version 7.1 or higher, thanks to which it will be possible to access a series of fun features. In fact, you can use apps to access social networks and above all see streaming content via Netflix or Youtube.

With Bluetooth, on the other hand, it will be possible to connect to smartphones, laptops and tablets to project videos and photos. Models equipped with these functions do not have the excellent image quality that can be found in those of the best brands, more expensive and at the same time less versatile. In general, however, almost all portable projectors have a USB port for reading multimedia files such as videos and photos.

Adjustment and battery

Not all portable projectors are the exact same size. Some models come with more compact sizes than others, particularly suitable for those who travel often for work and want to clutter up the minimum space in the suitcase. The advantage of portable projectors also lies in their positioning which does not require a tripod.

 

The important factor to consider is the focus adjustment which must have keystone correction in order to tilt the image correctly from any point. This feature present in many models allows you to place the projector on a shelf or a table which makes portable projectors particularly suitable for camping.

As for the battery instead, we advise you to look for a product with a rechargeable lithium battery of at least 5,000 mAh in order to cover a couple of hours of autonomy before having to connect the device to the mains.

Frequent questions

Can I see 4K and HD content on the projector?

Yes, many models support scalable resolution up to 4K. To see content at this resolution you will need to have a projector that has 4K or Full HD as its native resolution and therefore be ready to spend quite high amounts.

Most of the cheap projectors, if compatible with the signal in Full HD (or Ultra HD) will perform a compression of the image that will result in lower quality (in the best models, the most recommended for watching movies and playing games, with native resolution at 720p).

What does native resolution mean?

This is the ‘original’ resolution of a screen or in our case a projector. For example, if the projector has a resolution of 1280 x 720 pixels this will be the optimal one for viewing the contents. This can be ‘scaled’ or modified to reach higher or lower resolutions depending on the projected contents. The ‘scaling’ of the resolution downwards inevitably leads to a blurred image compared to the original one.

Do the mini projectors have speakers?

It really depends on the model. Those extremely compact for technical reasons of hardware do not have speakers, so you will need to get speakers or configure the audio so that it is reproduced by the TV.

As for standard portable projectors, some have built-in speakers which can have good sound quality too. In principle, however, for optimal results it is always advisable to get a couple of external speakers that are not too expensive. For home theater, you can connect the projector to the system by having the receiver manage the audio output of the device.

How long does a portable projector battery last?

The battery of a portable projector can last up to two hours of continuous playback without recharging. Usually these are very reliable 5,000 mAh lithium batteries that also allow you to connect the projector to the mains, which is advisable when you use it in the office, in order to avoid nasty surprises during an important presentation. In general, it is always good to have the battery fully charged, so as not to have doubts about its operation.

How much does a portable projector cost?

It really depends on the make and model. Let’s say that the projectors of giants like Sony and Philips are not exactly the cheapest, in fact they are around a cost of 500 to 1,000 euros. The models produced by lesser-known brands, on the other hand, can cost from 100 to 300 euros and have very interesting functions, but which in terms of image quality are significantly lower than the more expensive ones.

How to use a portable projector

How does the portable projector work?

The portable projector or mini-projector can be considered the ‘little brother’ of the classic projector with which it shares many features. Its use is quite intuitive, although there are some models on the market with different functions that can increase the possibilities of use.

The operation of a portable projector is very simple: first of all you have to make sure that the battery of the device is charged to one hundred percent or plug it directly into the socket with the transformer. Place the projector on a stable surface and connect it to the TV or game console via the HDMI cable and select it as the playback source with the remote control.

Keep in mind that to obtain an optimal result the environment must be poorly lit or completely dark. Now turn on the projector by placing it in front of the cloth or wall and start adjusting it, starting the console or decoder. You’ll have to work a little bit on focusing the image, as well as adjusting it in height and width. Once you have found the right configuration, you can consider finished the ‘setup’ of the product and enjoy the show.

How to connect the laptop to the projector

We talked about connecting with the TV and game consoles, but in reality the portable projector can also be connected to your laptop. This is particularly useful for powerpoint presentations at work or for university lectures. If your laptop has an HDMI port, then you can use the appropriate cable to connect it to the projector. Next you will need to select the display from the Windows Control Panel. The projector will be detected by the operating system as if it were a screen, so just select it to project the image.

It is advisable to select the function for viewing on two screens, so you can use your laptop to find files to launch more easily and manage the projection. If your laptop is older, you will need to use a VGA cable for the connection. But first make sure the projector has the proper input.

Please note that newer models may only have an HDMI connection, so before purchasing a product, please read the specifications and features carefully. One last thing: turn off your laptop screensaver and automatic screen shutdown, so you can avoid looking bad in the workplace.

How to connect the portable projector to smartphone or tablet

There are two very fast systems: the first consists in connecting the devices to the projector via a microusb cable, while the second involves using the Bluetooth connection. In this case you will have to activate it on your smartphone or tablet and search for the projector among the available devices and select it. Then, as you did with your TV or game console, you’ll need to choose the source on the projector using the remote control or buttons.

How to watch movies or photos from USB on the projector

Some models have a USB input to which external hard drives and pen drives can be connected. Once connected, using the projector software, simply select the source and access the various memory folders and subfolders. Select the file to play and that’s it.

What is the projector?

We used to spend cozy slide evenings in the past. To be able to view these slides on a screen, slide projectors were used to throw the picture onto a screen in a large format. The first video projectors were developed based on this technology.

With these projectors, which are also known colloquially as projectors, both standing and moving images, can be enlarged on a screen. The word projector is a pseudonym, which is derived from the English beam for beam or launcher.

Projectors are often used as a television replacement. These projectors are particularly practical for displaying a cinema film for several people on one screen. Home cinema users can achieve a real cinema feeling.

Most of these devices are still combined with a sophisticated home cinema surround system so that a perfect sound is guaranteed in addition to a large screen.

Video projectors can process a wide variety of input sources. With them, we can project an ongoing television program and play a film from a DVD or Blu-ray player. We can also connect a PC, a notebook, or another multimedia device to mirror the screen on a screen.

This is often used for presentation purposes in the business area or at school/university. But we can also insert a simple USB memory stick with various film files via the integrated USB port and play them back on the projector. The uses are very extensive.

Anyone interested in such a video projector will find functional, high-performance projectors for stationary use and small mobile devices for presentations.

 

The story of the beamer

The first projector was built in the 17th century. This is the famous LaternaMagica, which could not represent moving pictures but amazed the audience with picture lectures.

This lantern was developed by a Jesuit priest named Athanasius Kircher, who in 1671, wrote down the physical laws of projection in his work Ars Magna Lucis et umbrae. Here you can also find a drawing of the LaternaMagica mentioned above.

She celebrated her success primarily at fairs. Life-size representations of acrobats or clowns on moving glass pictures were presented. Later, expedition and travel pictures were presented to the public.

Later there were also smaller models for home use. The LaternaMagica served as an educational aid for children in fine houses. A flickering oil light served as the light source, representing pictures of animals, plants, and other interesting areas of knowledge about the lantern.

Only at the beginning of the 19th century were the oil lamps replaced by lime or gas lamps. This significantly increased the projection power, so that the light intensity was sufficient to present these images to a larger audience.

In addition to black-and-white images, color images were also presented. The small colorful pictures that were painted on a glass plate looked extremely natural. They can be seen as first slides.

The first video projectors, as we know them today, have their origin in the so-called Eidophorsystem. This was developed in the 1930s and first shown to thousands of spectators at the Summer Olympics in Berlin in 1936.

For the first time, spectators were able to experience the sporting spectacle up close on large screens. With the Eidophor system, it was possible for the first time to display moving images. We already presented this system and its principle of operation in a previous chapter.

This method was used until the end of the 80s and was then replaced by the tube projectors. The siderophore and the tube system required a separate projection system with optics for each basic color (red, green, and blue). The tube projectors were replaced by the modern DLP and LCD projectors.

Thanks to the latest technology, the construction could be compressed. Also, the optics have been adjusted accordingly, so that today’s devices no longer have to use three lenses.

The LED projectors are a further development of the DLP projectors. This projector uses LEDs instead of the projection lamp. This enables higher energy efficiency to be achieved than with projection lamps, and less heat is also generated. Operation with a battery is also possible with the LED projectors, which means that they can even be installed in mobile phones. The first marketable devices are already available.

LCoS projectors are still fairly new on the market and combine both DLP and LCD.

The crystals in these devices are no longer illuminated, but there is a mirror behind them. The technique of projection corresponds to that of a DLP projector. In the LCoS projector, there are cables behind the mirror surfaces which control the image surface.

This is the so-called screen-door effect, which is known from LCD projectors, reduced. These devices not only provide a very compact picture but are also easy to set up.

Laser projectors are currently used for the professional market. The image is created with the help of a modulated and quickly deflected laser beam. The laser beam is pulsed within picoseconds. The image is always projected line by line onto the projector screen.

Hazards that can be generated by the laser beam are excluded with the help of safety technology. This technology is currently still under development to be used in the private sector in the coming years.

 

Beamer – new trends

Many believe that the purchase of a projector is extremely expensive and considerably more expensive than good television. That’s not true. Projector projectors are easy to set up, easy to maintain, and cost little more than a good TV. Finding the right projector can, however, turn out to be a difficult task.

Whether you want to stream Blu-ray films over a large white wall, enlarge your gaming experience, or throw photos and videos from a mobile device onto a 100-inch-plus-screen – a good powerful projector should always be your first Be a choice.

 

We have selected the two best devices to introduce them to you.

BenQ TK800

The most important function of the BenQ TK800 is that the device supports 4k resolution (UHD). Also, the device’s DLP chip is not 3840 x 2160 pixels. The 4k projector uses a special XPR technology. This technology requires a smaller chip of 1920 x 1080 pixels. However, the device creates an image with over eight million pixels. The projector and its case are very bright (white). The device can produce images with incredible quality, although the environment does not promise optimal images. In the end, this means you can set up the device in a bright room, and you still get a high-quality image quality with incredible color depth and sharpness.

This projector is also suitable for gaming thanks to its excellent handling and low input lag. The BenQ has introduced a novelty: It is 3D supported – but you have to buy the right glasses separately.

For less than a thousand euros, you get a high-quality projector that is ideal for image and film recordings and gaming. The TK 800 is one of the best projectors in 2018.

JVC DLA-X5900

 

JVC is the leading brand when it comes to home theater. In the past ten years, JVC has followed as a projector brand for black levels and has grown from year to year. With the new D-ILA technology, JVC has created a novelty that can compete with DLP and SXRD models and is not available on the market.

This year, one of the most important upgrades is HDR performance. The power of HDR gives you an image that is many times larger than an LCD television and offers Ultra HD quality.

Before you buy, please note that the JVC DLA-X5900 does not contain any native 4K projector panels. Instead, the shifting technology from JVC is used, which projects two different 1080p images sequentially with a frequency of 120 Hz and thus shows the details of a native 4K display.

The new JVC-DLA-X5900 is the best 4k projector on the market and belongs to the absolute elite when it comes to home theater. With this device, you get unique pictures of a quality that can further enhance the home theater experience.

Epson EB and Epson EH series

The Japanese manufacturer Epson has a good reputation for projectors. Epson EB series projectors, such as the Epson EB U42 and Epson EB 2042 projectors, are offered in series on Amazon. The projectors of the EB series are in the middle price segment and have HD resolution. They are advertised as both home cinema projectors and business projectors.

In the Beamer Test 2018 of the StiftungWarntest, several projectors from the newer Epson EH series were tested. The Epson EH projectors are predominantly U HD projectors. The Epson EH TW5650 performed particularly well at the goodluckelectronics. The picture is very good (at the right angle), which is why it is also suitable as a business projector. However, the testers found the noise disturbing.

 

The right accessories for a projector

Do you have one of the modern projectors in your own four walls? This is anything but a rarity today because the projectors are enjoying increasing popularity with all their possibilities and capabilities. Again, this is certainly because the prices for modern and good projectors have continued to fall in recent months. But the technical possibilities also speak for the use of a projector, because more and more people want to take advantage of modern technology. The modern projectors from the lower price ranges are a good choice, especially as a replacement for a normal television. This is where the projectors cost only about 300 to 500 euros. Here, you can make a real bargain, even if this might look a little different at first glance.

 Most of the models and projectors available and available to you as customers today have very extensive and complete equipment. However, this equipment is not particularly extensive in everyday life, as many users, unfortunately, find out relatively quickly. However, this is generally not a problem at all, because there is hardly any other area in the shops that is as diversified as in the area of technology. As a user of the modern projector, there are also some parts of practical accessories that you are welcome to use in everyday life.

Today, every projector that you can buy from numerous manufacturers on the market generally has integrated speakers. The manufacturers and brands promise very good performance and good reproduction. Unfortunately, this looks very different in reality, and you, as a user, have to be satisfied with rather poor performance.

If you want to use the projector with the modern technology only for a presentation or only sporadically, this is, of course, no problem at all and the speakers, which are generally anything but good in the projector test, are no obstacle and no reason here why you have to decide to buy additional hardware.

But of course, it looks different if you are looking for a good and modern projector that is also a good and appropriate choice for your home cinema. In this case, the quality of the sound that the projectors produce will not be enough for you. Much of the important and good effects are lost here, making up a little film, series, or other content.

So if you plan to use the projector in your home theater, you should consider purchasing an additional sound solution. This is the only way for you, the user, to enjoy your new projector’s best audio experiences. Because you should note that even the very good and high-quality models of the projectors on the market in the projector test in the area of loudspeakers and audio technology are not very convincing. Also, the costs for these accessories have become manageable today, as prices have continued to fall in recent months and years.

A classic sound system or a modern soundbar is the right choice here. You will find corresponding models with high performance and good quality as a user and prospect on the market for a maximum of around 200 euros. Thanks to the easy handling and extensive equipment, these models are a good choice if you want to use the projector quickly and effectively in your home cinema with the best sound.

Another practical accessory from the range of accessories for a practical projector is the corresponding holder. Because, especially if you do not necessarily intend to use your new projector in different locations and rooms, many users endeavor to achieve a permanent installation. The advantages of such a procedure are, of course, obvious because, on the one hand, you have the option to place the projector safely and exactly as desired. On the other hand, it is also possible for you to Protect projectors from harmful influences and achieve optimal alignment.

In any case, both advantages are justified and are also very important. It is probably no wonder that more and more people are interested in a corresponding projector’s installation. There is a preferred location directly under the ceiling, because here the projector is securely mounted, but is also very suitable for optimal alignment with the desired wall.

Whether this is a white wall or a special screen, this is completely irrelevant and no longer plays a major role in the projector test.

You can find the holder for the modern projector on the Internet today, but of course also in specialist shops, in a very large selection. Because, of course, you must find a large selection of different models and brackets here. Because among other things there are different sizes and different load limits to choose from, for example for large projectors with correspondingly high weight or for projectors that are very light and small. And when it comes to installation, you will find clear differences and different versions of accessories in this area. Because among other things, there are models in which the projector is hung upside down, but normal brackets for the projector can also be purchased here.

A suitable and well-suited wall is not always freely available in your own four walls or in other rooms in which the projector is used. In many cases, however, this is a very big problem, because after all, the colors and pictures do not come into their own here. For example, if you want to use a projector to project the image onto a brightly painted wall, this may not be possible and, above all, is not a good idea.

After all, the colors are lost and the brightness that the modern lamps of today do not come into play here and you have to make a few cuts again. In this case, it is much more sensible and practical if you use a separate canvas. Again, you have a large variety of different models and variants on the market at your disposal. Among other things, the models on the market differ in a general way, because not all canvases are permanently installed. On request, the new canvas can even be used at different locations.

With a low weight and easy handling, these models are always the right choice if you either have little space within your own four walls or if you want to use the new projector in different areas and environments. Incidentally, the projector test also clearly shows that the screen is a good idea to significantly improve the picture quality.

 

The basic requirement for an optimal effect by the projector

As a rule, installing a new projector is not particularly difficult, because the manufacturers of the various models on the market also ensure this. With the intuitive operation and the particularly simple design of the menus, the projectors are even very suitable for technical amateurs, so that you do not have to cut corners here either. The products from this area also show in the projector test that operation and use are particularly easy.

You don’t just want to install and set up the new projector within a short time, of course, but at the same time, as a user, you also want to ensure that you can bring out all the pictures and content to their best advantage. You can also find some tips and tricks for this on the Internet if you are looking for them, and the projector test also shows you, again and again, tips and options with which you can get the best out of the projector.

But we also want to help you with this, because after all, the new projector should develop the optimal effect on your own four walls. We will now show you the most important requirements for this because apart from the simple and quick installation, you should also pay attention to this point.

Many people are not even aware of the importance of the right technology for an excellent display of all pictures in the desired quality. Of course, this is not necessarily a major problem for rare and sporadic use, but it looks very different if you want to use the new projector in your own home every day. This is the case, for example, in your home cinema within your own four walls. Unfortunately, today, many people have not yet dealt with the subject of technology that a projector with good performance alone is enough to produce good results and brilliant images.

However, this works much worse in everyday life than most people can imagine. After only a few days of use without special technology, people find that the projector cannot meet image quality requirements. The beamer test supports this assumption again and again.

You can do some things right when selecting and looking for a new projector to meet everyday life requirements. You should think carefully about what you want to do with the new projector and what requirements you place on it. If, for example, it is already clear in advance that you want to use the new projector in a normal living room, you should also note here that an appropriate brightness is very important. Because a projector is also often used in bright surroundings, this is very difficult for them.

Among other things, you must choose a projector with a correspondingly high brightness. With a brightness of at least 3000 lumens, you are well prepared for all scenarios and environments. Depending on the requirements and wishes of the purchased technology, a much higher performance is, of course possible, so that even a high brightness in the room used should not be a problem.

Nevertheless, you should also make sure that you align the new projector optimally and choose a good location. Because, of course, it is relatively pointless to use the projector in your living room or in another room where there is a direct and a brightness source. Because this will certainly be disruptive very quickly, so you should pay attention to this.

And if there is no suitable wall in the desired room, you should also make sure that you also use the right equipment. Modern canvas is the right choice because it is not for nothing that it is used again and again and almost every day, especially in a professional environment. Very practical: the screen can be extended and retracted on many models. So you don’t have to plan a lot of space in your living room or another room, for example, it can also be installed directly on a wall. It is very practical here that the projector test repeatedly shows very clearly that a modern screen makes sense.

The projector test also shows that the good models from this area are not particularly expensive. The investment is worth it. And here, too, you have the choice whether you want to order online or prefer to shop locally.

 

Structure & functioning of a projector

We don’t want to scare you with technical terms, but we think it’s important that you get an idea of a projector’s basic structure. Like all electronic devices, a projector also consists of various components.

In the following, we would like to explain the structure and the functionality a little. We leave out the outdated construction of a tube projector here. Here we present an example of the structure of an LCD projector. In the next chapter, we will also look at the other types.

Part of the basic structure

  • the lighting unit
  • the LCD unit
  • the cooling
  • the housing
  • the different connection options
  • internal speakers

The lighting unit

Normal metal halide lamps with a color temperature of around 5,200 Kelvin are used as the lighting unit. These lamps correspond to the brightness of daylight and can display colors true to the original. The advantage is that the lamp can generate the entire color spectrum with its white light.

The emitted portion of the light is reflected in the direction of an optical axis via a reflector as a concave mirror. The bundled light beams then arrive at a condenser lens, the task of fully illuminating the first Fresnel lens in front of an LCD unit.

As a result, the reproduction image is completely and uniformly bright up to the edges. Between the condenser lens and the first Fresnel lens, there is also a UV or IR filter, which largely reduces the ultraviolet and infrared components of the light.

This invisible part of the light is not required because it was previously not visible and would unnecessarily heat the LCD unit.

The LCD unit

The first Fresnel lens aligns the incident light rays in parallel to hit the LCD unit at right angles. The LCD can be called the heart of the projector since the actual projection image is also generated here. It is usually a transparent liquid crystal display.

However, a separate display is used for each basic color and combined into an image using a mirror system. By the way, the basic colors of a projector are red, blue, and green. The image passes through a second Fresnel lens and then hits the optics.

The look of a projector

The optics include a surface mirror, which is arranged at a 45-degree angle. This deflects the light rays with the projection image to the lens. The deflecting mirror has the advantage that the design of modern devices is kept quite compact.

The lens projects the image produced by the LCD unit onto the screen in a corresponding magnification. The focus or focus can be done either manually or motor-controlled.

The cooling

There are at least two fans inside the device, which ensure sufficient cooling. This is particularly important because the lighting unit heats up quickly. Unfortunately, the fans on inexpensive devices are quite noisy and disrupt the view for many. Expensive devices use damped ventilation systems.

The housing

Each manufacturer presents its design for the housing. It is usually made of hard plastic and comes in a variety of colors. The most popular colors are silver, black or white.

On the bottom, there are non-slip feet that are height adjustable. In most cases, a ceiling installation can be fixed on the top.

The different connection options

The back of each projector is particularly important. There are different connection options here. We can connect one to a projector.

  • TV to mirror the TV picture,
  • a DVD or Bluray player,
  • a PC or a notebook,
  • a smartphone or a tablet,
  • or a memory stick connected.

 

Most devices are for this.

  • USB ports,
  • HDMI ports or
  • Chinch connectors

Provided, often, several of a variety can be found there.

Some projectors can also be integrated wirelessly into a wifi network. Finally, the mains connection and the on-off switch must not be forgotten.

In addition, most models offer a small control panel behind which a protected cover.

  • Brightness and contrast,
  • vertical and horizontal keystone correction,
  • Lens zoom and
  • Input sources

To get managed. These functions can also be set using the supplied remote control.

Internal speakers

Many modern models inherently have a pair of speakers with an output between 5 and 20 watts. Even if you cannot replace a surround cinema system with these, these small stereo speakers still provide an impressive sound.

 

How is the projector connected correctly?

Of course, it doesn’t matter whether you have chosen one of the many good projectors on-site in specialist shops or buying via the Internet, you can quickly receive and use the new technology. As a rule, this is also one of the great wishes of customers and users who opt for such a projector and want to use it in their own four walls. After all, the projector should soon provide good pictures and entertainment in every living room or home cinema.

We would like to help you with the practical and extensive help and quickly use your new projector. Before this is possible, you must, of course, connect the projector correctly and properly. We would like to show you below how exactly this works and which accessories you need yourself.

Based on the practical instructions and in combination with the extensive information from the beamer test, you then have the opportunity to put the new projector into operation quickly and to be inspired by the best content in the desired quality.

Ultimately, of course, some cables and technologies are part of every modern projector today and, therefore, also play an important role in the projector test. However, there are, of course, clear differences, which come into play when the connection is correct. This point then naturally refers to the interfaces, because these should not be missing from the projector, of course, so that hardware for playback can only be connected to it. In the best case, look after that the new and own projector has an HDMI connection. Because this is not just a current standard, but at the same time, this technology is also very practical. Because with HDMI, both image and sound can be transmitted simultaneously with just one cable, and you do not have to take any major measures to connect the projector.

For this, you should attach great importance to a good cable in the usual quality, because this pays off in any current application and long-term use. You can find good cables of the desired quality on the Internet in the large shops, but you are also welcome to look around for an HDMI cable in a local store. However, you should not only attach great importance to the general quality and long durability, because other points also play a very important role in a modern HDMI cable. Among other things, the standards used for cable play a very important role in both resolution and sound. Because many models in the area of the projectors already have a resolution which is significantly higher than r Full HD resolution.

Although these projectors also have excellent image quality in the projector test, some peculiarities of both technologies are to be expected. Because not all cables and all interfaces on the projectors have the option of displaying this high resolution, so you should pay attention to this when looking for the new cable.

For the connection of further functions and cables, you should value intelligent and clean cable management. This is the only way to keep an overview and order in your home cinema. This applies above all to use in a fixed installation, for example, with a special bracket directly under the ceiling. In this case, you should, for example, use one of the inexpensive cable ducts, these only cost a few euros and make the cables disappear inconspicuously. Here, too, the installation is very simple and can be done within a few minutes, using simple screws or self-adhesive products.

Another point in the context of the important and necessary installation is the power supply. After all, every projector needs a permanent and constant power supply to use it, so that it can function properly. In general, the installation or connection of the power cable should not be a problem even for perfect laymen in technology. Still, here, too, of course, safety is important. So it is best to ensure that the cables are not exposed in the room. Because even a short pull on the cable or even stumbling, as can occur, again and again, can cause the projector to fall.

Due to the sensitive technology, this is very quickly a defect, and the projector can then no longer be used, as usual, so you have to search for a new one. With a clever and intelligent installation, you, as a user, can avoid this effort and, above all, the very high costs without any problems. If the cables are to be laid and installed on the floor, for example, it is always advisable to run them directly on the wall.

Alternatively, you are, of course, welcome to use a cable duct here. Because here, too, this not only provides a significantly better visual impression but also increases security by directly covering and hiding the cables.

If you have then supplied the projector with the necessary energy and the source for the reproduction of the images is installed, there is almost nothing standing in the way of using the projector. This only looks a little different if you, as a user, cannot or do not want to do without the accessories mentioned above. If, for example, you would like to significantly improve the experience of using the projector with a modern sound system or a practical screen, this is, of course, possible. Still, again you have to carry out the necessary installation before the application is possible. However, this is usually not a problem either.

The fact that the manufacturers provide practical instructions for installing the necessary technology is very practical. You then simply follow this step by step as a user, and after a short time, this is also done. If you have installed and connected the accessories, you have already completed the last step. The new projector with modern technology is now finally ready for daily use in your office or your own four walls. We wish you lots of fun and success.

 

What types of beamers are there, and what are their advantages and disadvantages?

As we will see shortly, a projector is not just a projector. There are many different types on the market. We would like to introduce the most famous representatives here and thus bring a little clarity in the jungle of technical terms. A distinction is made between the following video projectors:

  • DLP projector,
  • LED projector,
  • Tube projector,
  • Eidophore system,
  • LCD projector,
  • LCoS projector and
  • Laser projector.

The DLP projector

The currently largest offer is the so-called DLP projector. The abbreviation DLP stands for Digital Light Processing. As already explained above, the image converter is the heart of a projector. A DMD is used for a DLP projector. This digital micromirror device is an integrated circuit that provides a tiny tiltable mirror for each pixel that can be displayed controlled by an electrical pulse. By specifically controlling these mirrors, the light is either directed into the projection optics or deflected directly.

As with a dual system, the mirrors can only assume the two states on or off. For this type of image generation, brightness gradations can only be achieved by quickly switching (pulsing) the tilting mirror. This is achieved by switching the tilting mirrors up to 5000 times in one second.

The generation of a color image from only two states is quite interesting. The manufacturers of DLP projectors use a fast rotating color wheel for this. The DMD can use this rotating color wheel to project all three basic colors, one after the other. Current DLP video projectors use a color wheel that has six or seven individual color segments. This allows the colors to be mixed even more precisely, leading to a better image result.

In addition to colored segments, some manufacturers also use a transparent segment in their color wheels for new DLP projectors. This should significantly increase the light output when rendering white areas. The disadvantage is that a separate transparent segment reduces the overall color light output. In this way, poor color rendering is achieved on very large projection surfaces.

High-performance DLP projectors are also used in the cinema. They have three separate DMD image converters and thus compensate for the disadvantages mentioned above. Later we come to the LED projectors, which can switch their colors electronically. The only company that currently provides DMD technology is the American company Texas Instruments.

Advantages of the DLP projector in one test

  • high speed,
  • no afterglow of the picture,
  • no burn-in of still images,
  • higher contrast than with an LCD projector,
  • Black is reproduced particularly vigorously,
  • hardly any pixel artifacts and
  • less sensitive to dust than LCD projectors because the optics are encapsulated.

Disadvantages of the DLP projector in one test

  • Rainbow effect, when the color wheel is not running fast,
  • optimal image resolution depends on the built-in mirror matrix,
  • individual colors can flicker,
  • not all colors are reproduced true to the original,
  • Color wheels with a transparent segment achieve a poorer color light output than LCD projectors and
  • higher noise level due to the color wheel and fan.

The LED projector

In a projector test 2020, test subjects also looked at LED projectors. With these video projectors, the image is still generated via a DLP element or, in newer models, via an LCD. LEDs are only used as light sources. LED stands for Light Emitting Diode and is one of the most popular electronic components for signal display.

The light output of LEDs is not particularly high, especially in the green area. Here the light wavelength only reaches between 540 and 610 nanometers. For this reason, LED projectors are also known as hybrid products among connoisseurs. To achieve a strong green, this color is not displayed with an LED, but with a laser diode. The colors themselves are formed by the sequential lighting of each individual LED.

Many LED video projectors have already replaced the previous DLP projectors. They are much more durable and can also be built with very small dimensions. LED projectors are the ideal solution for mobile applications, such as when it comes to visually supporting a business presentation. Another plus compared to other video projectors is the low heat development during operation.

Advantages of the LED projector in one test

  • LEDs are more energy-efficient than other projection lamps,
  • cooling is not necessary,
  • LED projectors can also be operated with a rechargeable battery due to the lower energy requirement,
  • the housing dimensions can be minimized,
  • the lifespan of LEDs is around 20,000 hours. Conventional lamps reach 4,000 hours and
  • a color wheel is not required for the color representation by the LEDs.

Disadvantages of the LED projector in one test

  • LCDs as image generators only achieve satisfactory image quality with fixed resolutions. The overall light output is lower than with other video projectors,
  • Due to a so-called decrease in the LEDs’ luminous flux, the image to be displayed can become constantly darker. Only an adaptive increase in current can compensate for the loss of brightness and rainbow effect since the primary colors are projected one after the other.

The tube projector

The so-called tube projectors were among the first commercially available video projectors. These projectors use traditional cathode-ray tubes for image display. These video projectors were still very large and heavy. Their tubes were aimed at a very high brightness so that a sufficient projection could take place.

The first devices with three lenses presented themselves optically. This was because a cathode ray tube was required for a color projection for each basic color. Each tube, therefore, had its lens. By superimposing the three projections, the color image could finally be viewed on a screen.

The brightness and resolution depend on the size of the cathode ray tube used. At the time, the sizes 7, 8, and 9 inches prevailed for projection tubes. Furthermore, a distinction was made between electrostatic (ES) and electromagnetic (EM) projectors about the best sharpness representation of the electron beam.

The 9-inch projectors with EM focus are still in use today. They are used in expensive flight simulators and also in high-end home cinema systems. The tube has not yet had its day here. The seven and 8-inch projectors, on the other hand, were often used in rear-projection televisions. Today, good used projectors of this type are rarely found.

Advantages of the tube projector in one test

  • Tube projectors can display all common resolutions such as NTSC, HD, Full-HD and 3D content,
  • the line-oriented representation of the tubes is much more natural compared to pixels,
  • there is no time delay so that videos with interlacing or interlacing can be played back without any problems,
  • the tubes themselves generate the required light so that no additional light sources are required,
  • the life of the tubes is around 10,000 hours and
  • Tubes achieve good black works and excellent contrasts up to 30,000: 1.

Disadvantages of the tube projector in one test

  • Tube projectors have only a low overall brightness so that the room must be darkened during playback,
  • the cathode ray tubes are sensitive to burn-in from still images and can darken in the affected areas,
  • the three color tubes and lenses have to be set in a complex manner so that mobile use is generally not possible,
  • Tube projectors are characterized by a heavyweight,
  • high ghosting effect in 3D rendering, because the tubes have a long decay time of certain phosphor types and
  • Devices are still very expensive, even when used.

The eidophore system

The so-called eidophore system is almost forgotten. It was developed in 1939 by Fritz Fischer, an engineer from Switzerland. It is the first method for the large-scale projection of television pictures. Eidophor is a Greek term and means something like an image carrier.

A xenon gas discharge lamp is used to generate light in the eidophoresystem. From there, the light is guided via a bar-shaped mirror to a concave mirror, which is part of a cathode ray tube. The concave mirror is provided with a thin oil film and is bombarded to different degrees by the tube’s electron beam.

At the same time, the oil layer changes and causes the light to deflect in the beam path. The light is reflected through the bar mirror and reaches an opposite collecting lens, representing the lens. As a result, a pixel is projected. To be able to display a color image, three parallel eidophore systems must be used.

The Eidpphor system was still in use until the end of the 1980s. The excellent image quality characterized it. This system was replaced by the tube projectors and later by the LCD and DLP projectors.

We do not need to go into the advantages and disadvantages here, because this old professional system is no longer used today.

The LCD projector

When we talk about an LCD projector, we mean a liquid crystal projector. They work much like a slide projector. But instead of a framed slide, several transparent active-matrix liquid crystal displays are used here. Thin-film transistors drive these.

To display color images, today’s LCD projectors use three independent LCD matrixes or 3LCD technology for short. In this way, any primary color can be displayed. The actual projection of the entire color image takes place via specially arranged, dichroic mirrors. For a brilliant reproduction, the individual colors are superimposed and not displayed side by side as in conventional LCD monitors.

High-quality LCD projectors use yet another LCD matrix. In addition to the basic colors red, green, and blue, there is also one for the bright display of the color yellow. In this way, a high luminous efficacy can be achieved and an extremely good color balance. For models with 3LCD technology, the basic display often shows a slight yellow tinge.

There are also LCD projectors with only one liquid display. The three primary colors are then displayed on three adjacent matrices. Unfortunately, this leads to poorer resolution.

Advantages of the LCD projector in one test

  • inexpensive,
  • due to the sharp delimitation of the pixels, texts and graphics are extremely sharp,
  • the small and light construction of the projector possible and
  • the better color intensity with the same light output than DLP projectors.

Disadvantages of the LCD projector in one test

  • Keystone or perspective corrections are difficult to carry out with LCD projectors since the LCD matrixes have a solid structure and would otherwise be blurred.
  • older LCDs are characterized by a streak effect,
  • Liquid crystals need a constant temperature and must not slip into the liquid phase,
  • a fan system is required and is usually annoying to hear during playback,
  • LCDs with organic liquid crystals tend to burn in (LCD memory effect), which can occur after only 1,000 hours of operation,
  • LCDs are sensitive to smoke and dust that can get inside through ventilation
  • incorrect convergence possible because color images of several LCD matrixes are projected overlaid.

The LCoS projector

Further development of the LCDs is the LCoStechnology. LCoS stands for Liquid Crystal on Silicon. This method also uses liquid crystal displays, but the LCDs are used in reflective mode. In contrast to DLP technology, there are various brand names from renowned electronics manufacturers on the market. Sony calls its process SXRD. Sanyo calls this technique D-ILA or DLA.

The projection itself is similar to that of a DLP projector. The liquid crystal displays are mounted on a reflector with control electronics underneath. The advantage is that the signal lines of an LCoS chip for controlling individual pixels are considerably shorter than with a conventional LCD. This also reduces the dreaded fly screen effect of LCD projectors. Overall, an LCoS projector achieves a higher contrast value and a very deep black area.

Advantages of the LCoS projector in one test

  • Projectors can be built compact
  • extremely sharp representation,
  • only slight loss of brightness and
  • very good black levels, similar to CRT monitors.

Disadvantages of the LCoS projector in one test

  • fixed resolution of the LCDs in the projector does not always ensure perfect picture quality,
  • Pictures can easily follow
  • there is also the LCD memory effect here and
  • the image and color quality may deteriorate as the operating time increases.

The laser projector

Laser projectors are designed for the professional market. These devices achieve their image composition via a quickly deflected and modulated laser beam. We can find two different structures here. There is laser display technology and grating light valve technology (GLV). Interestingly, these projectors’ lenses do not serve the image, but only to expand the light beam.

Laser display technology (LDT) was developed in Gera and Jena. Here the projection image is written line by line on the screen. As already mentioned, tube projectors also write the projection line by line onto a screen and thereby achieve a much better image quality. At the LDT, a special scanner with a facet mirror ensures a line structure, whereby a tilting mirror initiates the next line feed. The modulated laser beam can determine the correct brightness and color for each pixel. GLV technology is not quite as mature since the infamous speckle pattern can still occur.

The laser is pulsed in the pico-second range for almost perfect image reproduction. The viewer need not be afraid of the laser since appropriate safety mechanisms ensure unproblematic operation. Today these professional projectors with laser technology are used for flight simulators. This means that even curved projection surfaces can be used.

Advantages of laser projectors in one test

  • projection surfaces of any shape can be used,
  • focusing is not necessary
  • Laser projectors have a very high contrast range and
  • the basic colors are mixed with brilliant quality to form an overall picture.

Disadvantages of laser projectors in one test

  • there is only a limited light intensity available,
  • Laser class 4 for LDT and class 3R for GLV so that only trained personnel are allowed to operate these devices
  • without protection, there is a risk to eyesight.
  •  

Laser projectors can even create 3D holograms.

Power consumption and radiation of a projector

It is worth looking at the power consumption of a projector because, depending on the technology, projectors are considered large power consumers. However, one should when operating a projector with the power saving not overdo it. Frequent switching reduces the lifespan of the device.

Calculation of the electricity costs of a projector per screening

The calculation of the electricity costs can be carried out with this formula:

Power of the projector (watt) x presentation time (h) x electricity costs (Ct / kWh)

The performance of the projector can be found in the operating instructions. However, it is usually also on a rating plate directly on the projector. The rating plate with details of the nominal voltage and power consumption is usually attached to the bottom of the device in the form of a sticker.

A calculation example :
  • Power consumption of the projector: 250W
  • Presentation duration: 2h
  • Electricity costs: 30 cents / kWh
  • Electricity costs: 250W * 2h * 30 cents / kWh = 15 cents

With the help of this calculation, it can also be demonstrated that switching the projector off briefly during breaks in presentation does not result in major cost savings. However, the life of the lamp is reduced.

Radiation of the beamer

The high light intensity of the projector can cause damage to the sense of sight. The projectors should, therefore, be placed in such a way that lecturers do not have to look directly into the light of the projector. As a rule, the eye closes automatically when it is illuminated directly by a light source. However, there is a certain danger if the lecturer does not look directly into the light source, but the light rays nevertheless reach the retina.

This is remedied by installing the projector on the ceiling. The lecturer can thus look at the audience while the rays of light hit the screen from above.

Another variant would be the renunciation of presentations in full daylight, even if the projector to be technically capable. By darkening the lecture room, the light intensity of the beamer, and thus the risk to the lecturer, can be reduced.

 

Ongoing care and cleaning of a projector

To ensure excellent image reproduction, certain parts of the projector must be maintained consistently. However, this requires certain technical knowledge and skill. It is not always possible to tell whether a loss of quality can be remedied by cleaning or readjusting individual components.

For this reason, a professional should rather be entrusted with cleaning to ensure trouble-free operation.

Clean the filter

The easiest way to clean or replace the filter yourself. This process should not be neglected. A dirty filter leads to progressive contamination of the optical elements ( loss of quality) and a reduction in the cooling flow in the event of a blockage. The result is the heat death of important components of the device (total loss).

Therefore the filter should be cleaned after 100 operating hours at the latest. The device must be disconnected from the circuit before cleaning. If the device has just been used, wait for the cooling phase.

Existing filters can usually be used several times. A simple wash is often sufficient for cleaning. Cleaning with compressed air is very often recommended. There is a risk that the harmful particles are not removed, but only distributed and maybe even more sprayed onto the optics.

Clean the lens

Depending on the applied technology – in particular in the management of Lüf t angstroms – Particle place at different rates on the lens. The cleaning should rather be carried out by specialists.

Readjustment of the LCD block

With LCD beamers, the image is generated by three-color panels. These panels must be precisely coordinated. If this coordination is disturbed, for example, by vibrations in the device, a convergence error occurs.

Since a shock or knocking of the device, especially with mobile devices, cannot be ruled out, regular adjustment of the panels is necessary. However, this measure should also be carried out by a specialist.

Replacement of the lamp

Even if replacing the lamp seems trivial, you should consider whether you can have the lamp replaced with a specialist’s professional cleaning.

Since the devices are quite sensitive to vibrations, opening, and closing the devices, unprofessionally could lead to permanent damage. Above all, it is not always clear to laypersons which parts they can attack and which parts should never be touched.

Average lifespan & disposal

lifespan

In the case of a projector, the lamps are a wearing part. Depending on the technology, it is necessary to change the lamps from 2,000 hours. In addition to the technology but also the decision use manner about the lifestyle.

The lamp life can be extended by operating it in economy mode – called eco mode on many models. Constant switching of the device reduces the life of the lamp. It is, therefore, appropriate to leave the projector switched on during a short presentation break.

Expensive devices have various measures to protect the lamp. Since a lamp exchange very high cost, they should be the higher cost of a lamp-saving model is compared.

The lifespan of a projector can also be extended by moving it as little as possible. Vibrations reduce the lifespan of the projector. Users who take this recommendation very seriously even prefer to use the remote control to leave the projector untouched.

With LCD projectors, the light intensity and color brilliance decrease with continuous use. The causes for this include dust and cigarette smoke. The decrease in the playback quality of the installed panels varies.

The blue panel is particularly affected, which is why the loss of quality is most noticeable in this color range. The LCD projector is used up after approx—5,000 operating hours.

When using LCD technology, the cooling air is guided past the optics. Even with filtered air, this variant will sooner or later lead to the deposition of particles on the optics and reduce the reproduction quality.

With DLP beamers, the cooling air is guided around the chip differently. The loss of quality due to particles on the optics, therefore, occurs much later and increases the lifespan of the projector in terms of playback quality.

Operating times of up to 20,000 hours are also possible with LED projectors. This suggests that the next technology leap in projectors will occur faster than the life of the current projector has ended.

disposal

Depending on the technology used, projector lamps contain substances that are harmful to the environment. Therefore, they must not be disposed of with household waste and do not belong in the material bin. Instead, you should take them to one of the municipal collection points or hand them into the mobile pollutant.

If a projector is broken or outdated, a new purchase is necessary. Numerous providers take the old projector back or even trade it in. This also automatically clarifies the question of disposal. It is, therefore, advisable to search specifically for such providers.

Against this background, it can also make sense to replace the current projector when its service life has not yet expired. So you get a higher redemption price for the still operational.

Typical defects and reasons for return

The technology of a projector is very complex. This applies both to the interior of the device and to the correct choice of its location and its projection surface. The anticipation of a great picture experience quickly gives way to disappointment due to real or supposed defects.

The following list lists frequently mentioned deficiencies and reasons for return. Besides being a device that is actually from the beginning may be defective, it is here for possible additional causes for lack of display quality described the equipment and some remedies offered.

We attach particular importance to the importance of the trapezoid effect and the canvas. Many supposed deficiencies can be remedied or reduced by clarifying the importance of quality canvas and a carefully chosen location.

The remote control does not work.

Remote controls often shake the basic trust of their users. You push and push, and you achieve nothing. In addition to a real malfunction, this could also be due to outdated batteries.

In addition, their range may not be sufficient. The functionality also depends on whether the receivers on the device can be reached by the remote control.

IR remote controls require a line of sight to the receiver on the device. With the lecturer’s positions constantly changing, receivers would be needed on several sides of the device.

The use of an RF-IR extender can be helpful. This converts the infrared signals into radio signals and thus avoids the problems described above.

The cables supplied are too short.

The distance between the projector and the data processing unit can be very far apart. This is especially true when installing the projector on the ceiling. When purchasing the projector, the procurement of correspondingly long cables must be taken into account.

The projector is not bright enough.

Projectors are not suitable for every brightness. Many projectors require darkening in the room. Organizationally, this darkening cannot always be ensured or is often not desired at presentations. Therefore, when buying a projector, it is important to ensure that it is suitable for daylight.

A darkening and thus no longer necessary image brightness but can also have their advantages. This reduces the risk to the lecturer’s eyesight due to excessive light rays. In addition, darkening and reducing image brightness can reduce the cooling requirements of the device. As a result, the use of a noisy ventilation system is reduced.

The image intensity is not strong enough.

Users often spend a lot of money on a good projector and are disappointed if the picture is not thrown onto the wall in high contrast and colorfastness. The error here could lie in the choice of canvas or even in the absence of a canvas.

The projecting directly onto a wall does not allow high quality of image reproduction. The white of the walls is not always pure white. Even the smallest structures in the wall come into conflict with clean image reproduction.

This is remedied by a canvas that is optimized for the correct reproduction of the image. A coating with vinyl fibers ensures that the canvas does not wrinkle quickly and can be cleaned with a damp cloth and a cleaning agent.

When purchasing a canvas, the gain factor must also be considered. This measure describes the reflective properties of the canvas. With a factor of 1, the light is reflected evenly in all directions. If the value is higher than 1, the image in the center appears brighter than on edge. If the value is less than 1, the opposite is the case.

Therefore, the gain factor decides whether all guests get the same impression of the picture quality with a larger audience. If the factor is not equal to 1, the viewer’s seating position decides on his image perception.

The projector (fan) is too loud.

One of the most common reasons for returning a projector is that the ventilation system is too loud. This is often not noticeable even during the demonstration in the specialist retail store. Ambient noises such as street noise or consultations drown out the noise of the freshly started fan.

After the projector has been in operation for a long time at home or in the office, the fan noise is suddenly perceived as much louder. On the one hand, this is due to the completely different perception of noise in lectures where there is otherwise calm. On the other hand, setup errors could also play a role.

Too little space around the fan slots increases the use of the fan. This error often occurs when you set up the projector on the bookshelf, for example. The distance to the books should be at least 20 centimeters here.

Another way to keep the fan noise moderate is to operate the device in eco mode or a little more darkened room. Both reduce the necessary light intensity and associated noise development.

Defective setting options for keystone correction

Lecturers are familiar with this situation: shortly before the lecture, the agonizing adjustment of the keystone correction begins. This is used to correct a trapezoidal representation of the image on the canvas. This project is not always successful.

Apart from the fact that the adjustment of the keystone correction may be defective, you should consider before returning the instrument: The correction of the trapezoidal representation using the Keystone settings is only the second choice.

The trapezoidal representation indicates an incorrect installation of the device or the screen. Therefore, more attention should be paid to correction when setting up both elements. This may not always be possible with mobile devices is constantly changing locations. This correction function should not be necessary when installed in a stationary position, for example, when installed on the ceiling.

In this context, it is also important to know whether a device generates the equalization with the help of a lens shift or with the help of conversion by the software. Lens Shift solves the task better but is only available in correspondingly more expensive devices.

When correcting the keystone display, a distinction must also be made between vertical and horizontal correction. The horizontal correction should be avoided by placing the projector exactly in the center of the screen.

If the projector is exactly in the middle of the screen, the error could also be provoked by a slightly slanted or hanging screen. Even if that sounds unbelievable for modern people: walls are not always built as horizontally and vertically as one would expect. Owners of apartments and offices in old buildings can sing a song about it.

Vertical correction is not so easy to avoid. The trapezoid effect is mainly because, in many cases, projectors are mounted in a position that is too low or too high. For a reasonable image display, they must be set up at an angle or hung.

Since this set-up problem represents a standard situation, more expensive devices automatically recognize the inclined set-up and correct the trapezoid effect internally. And if both internal and external corrections are not sufficient: with a little skill, the screen can also be installed at an angle, which should further reduce the trapezoid effect.

Just a combined slider for image size and sharpness

A combined slider for image size and sharpness has the disadvantage that the image size depends on the distance between the device and the screen. The distance between the device and the screen can not be designed arbitrarily in small rooms. This is remedied by devices in which the image size and sharpness can be set separately.

The resolution is too low

Buyers of low-resolution devices are initially pleased with the cheap purchase. Photos from the last vacation or one or the other film come out well enough. At the latest, when used as a presentation device, there is a big disappointment.

At low resolutions, there are usually difficulties with the representation of fonts. If the font is very small, it quickly becomes illegible. This could be remedied by changing to a device with a higher resolution.

Before returning the device, you should consider whether you can improve the installation of the device. Extensive use of the keystone correction (see) leads to a strong loss of quality in the resolution.

The sound system is too quiet.

If the device’s sound system can only be operated at a limited volume, there is a risk that spoken texts cannot be played sufficiently loud. This weakness, in combination with an overly loud ventilation system, gives rise to dissatisfaction.

As a rule, this deficiency can be remedied by using an external sound system . Especially if the focus is on very good sound reproduction (keyword: film music), an external sound system should be considered.

Colors are falsified

An incorrect reproduction of colors right after the device’s purchase can result from a poor choice of the screen or a direct projection on a wall. If the error only occurs during use, it may also be due to the technology’s natural aging process. With LCD projectors, the individual color panels age at different speeds.

A misrepresentation of colors could also be because the color panels of LCD beamers are no longer exactly coordinated. In this case, one color dominates over the other. For example, it could happen that the white house walls in the vacation photos from Puglia suddenly appear in clear green.

If the error described above occurs immediately after purchase, the device may have been shaken during transport, and the convergence of the color panels may have been disturbed. If the error occurs after some time, the device may have been moved too much or even bumped into its premises.

With DLP devices, the error could also have occurred on the color wheel or in the color wheel control.

Strong pixel formation

If the distance between the device and the screen is small, errors in the pixel formation are particularly noticeable. A greater distance can help here. Extensive use of keystone correction also leads to increased pixel formation on the screen.

The picture flickers

After prolonged use, a flickering image would on the imminent demise point of the lamp. If the error occurs after connecting the device for the first time, there are probably problems with the contacts on the board or the plugs. If the image changes to black and white, this is an indication of a broken color wheel.

Stripes appear in the picture.

Similar to picture flickering, stripes in the picture indicate contact problems with the circuit boards or the connectors.

The picture is strikingly dark.

This error would also arise after long use of the lamp. If the error occurs from the beginning, the iris diaphragm may have failed. This usually helps to represent the black in a picture in a rich black. If the iris fails, the entire image is darkened.

Beamer shows light or dark dust grains in the picture.

If this error occurs with LCD projectors after a long time, it could be caused by contamination. With DLP projectors, a fault pattern indicates a defective DMD chip in which one or more micromirrors have failed. This is especially true when these ‘dust grains’ appear very clearly outlined.

The image is generally out of focus or blurry.

If all recruitment efforts have failed, the following options must, unfortunately, be considered. With DLP projectors, the lenses could be contaminated. In LCD projectors may be a polarizing filter is burned. In the latter case, the device should be sent back.

Dark or pink bars blur the picture.

With DLP beamers, an error pattern indicates a broken or shifted mirror channel. With LCD beamers, it could be due to a shift in the prism glasses in the optical channel.

Darkened corners create nostalgic feelings.

Sometimes projectors produce images with darkened corners. This phenomenon is called vignetting and is usually known to us from old photos. Today vignetting is often used in photos to achieve a nostalgic effect. In the case of projectors, especially the designated short-range projectors, this effect indicates cheaper optics. So it’s less a matter of harm, more a question of price.

 

How were the packaging and delivery tested in tests?

 

When packaging, a projector must always ensure that it is stable. If there is too much air between the packaging and the projector, it can be damaged during transport. When packaging, make sure that there are no traces of water.

Also, the projector should not only be in a simple box but also have a protective cover.

The delivery always depends on the provider. The device can be delivered within 24 hours or after a few days. However, most providers only offer 24-hour service at an additional cost.

What data and facts have been tested?

The lighting conditions are very important for a projector. Sensible projectors can provide a clear picture even in a slightly darkened room. In our experience, the projector should have the following standard situations. The device should have at least 2000 ANSI lumens on the lower edge and 4000 ANSI lumens on the upper edge.

The insert lamp of the projector is also not to be neglected. In most cases, the lamps have a lifespan of 4000 to 6000 hours. There are also lamps with a lifespan of 2000 hours. However, it should be borne in mind that the picture gradually deteriorates and that replacing a lamp is usually associated with high costs.

Depending on the manufacturer, the replacement price can be between 200 and 700 euros. When it comes to lamps, the guarantee provided by the manufacturer should always be observed.

You can also opt for an LED projector where you no longer have a lamp. The efficiency of these devices is extremely high, and they hardly need cooling. However, the technology is not yet so sophisticated that the brightness can be increased.

The air noise can be an enormous disruptive factor when presenting with the projector. The quieter the device, the smoother the presentation will be. Especially projectors with a low lamp output since less heat is generated and therefore has to be removed. The airflow in the housing also plays a major role.

The noise is generated by the fan and the airflow. The frequency of this noise is always dependent on the projector’s housing, which is why it would be exaggerated to say that you should use the manufacturer’s dB specifications as a guide. With some projectors, dB is also listed in the ECONOMY position of the insert lamp. With this value, you should always critically question whether the stated value can also be maintained with a series of devices.

Whether the projector should be mobile or stationary is up to you. However, the weight and dimensions of the device play a major role in this factor. The smaller the projector, the easier it can be used on the go. It should also be noted that when the beamer is transported, the technology can also suffer.

With frequent transport, an LCD projector is more advisable than a DLP projector because it contains numerous individual mirror bars. In most cases, projectors weigh between 2.5 and 6 kilograms.

When buying a projector, the projection size should always be considered. You should find a reasonable compromise between room size, resolution, and image size. With an LCD projector, pixel structures on a screen can be perceived as disturbing. You should also keep in mind that the brightness is reduced by four if the picture is twice as wide. You can easily calculate this – Divide the Ansi Lumen by the area of the canvas.

You should also consider formats with a projector. Most projectors have the usual formats of 1: 1, 2: 3, 3: 4 16: 9, 16:10, and 20: 9. For data to be displayed adequately with a projector, it requires a 4: 3 chip. Most standard devices already have such a chip. In some cases, there is also a 16:10 chip in the projector. If the PC has a different resolution than the projector, it must either be converted, or some pixels are simply not controlled.

The zoom does not replace the interchangeable lens on a projector. In most cases, the focal length ratio telephoto wide-angle is a factor of about 1: 1.2 or 1: 1.3. A motor zoom only rarely makes sense with a projector. Once this has been set, neither the zoom nor the sharpness changes.

However, many devices offer the option of digital zoom. This can be set using the remote control. Since the digital zoom is bad for image sharpness, a good lens with an optical zoom should be considered.

Analog signals, YC, and RGB input are also important aspects of a projector. You need a so-called coding technique so that your pictures can be displayed in color from the video. PAL’s color system uses a nesting of colors and brightness (C stands for chroma and Y for luminance).

However, this results in a lack of resolution, which is why YC-SVHS technology and RGB have been available on the projector for several years. Also, some devices have an S-VHS output and an RGB output. RGB is output as red, blue, and green at the socket.

If the device is equipped with an RGB input, there is an improvement in the image quality. The YC input is also comparatively good because both the monochrome image content and the colors are transported and processed separately.

HDMI represents digital signal transmissions. There are no analog detours. These signal transmissions are already widespread in the private sector. If you buy a home cinema projector, HDMI is essential.

It is entirely up to you to decide whether you need a ceiling mount for the home cinema projector. However, the device requires both a vertical and a horizontal image reversal for this. If the projector does not have this function, the image is permanent upside down. It can be said that almost all projectors already have this feature.

equipment

When purchasing, make sure that all necessary cables are supplied by the manufacturer. If this is not the case, you have to buy the required cables yourself before installation. In most cases, home cinema projectors are sold to the customer with all the trimmings. There are usually batteries, even for remote control.

Guarantee and services

Manufacturers usually give a two-year guarantee on a projector. However, some manufacturers offer a guarantee that extends beyond these two years. However, I always pay attention to the scope of the guarantee services. In some cases, the guarantee is not always free but has to be paid for at an additional cost.

You should also inform yourself about the manufacturer’s warranty for the lamp. Depending on the manufacturer, the guarantee on individual parts can vary greatly.

The manufacturer’s service should also be carefully examined for the projector. This can be very diverse. Everything is possible, from on-site service to send in the device.

The air filters of a projector should be cleaned on average every 200 operating hours.

This can increase the life of the lamp. When servicing, you should always pay attention to the following factors: travel allowance, travel costs, and hourly rate.

Price-performance

The cost of a home cinema projector can vary widely. From 500 to 8000 euros, almost anything is possible with this device. You should keep in mind that additional costs are usually associated with better image quality. Therefore, you should perhaps invest a little more at this point to get more benefits from the projector.

How is the projector connected?

In most cases, connecting the projector is not witchcraft and self-explanatory. The existing cables can only be plugged into the specified sockets. You can’t make a mistake there. Cinch cables offer low picture quality. The S-Video connection already works with two channels (color and brightness).

In terms of quality, the S-Video cable is always better than a cinch cable. The VGA connector is a 15-pin connector. Images are transmitted on an analog basis. The VGS cable offers good image quality and only needs to be screwed to the output and input device.

With the VGA-Out connection, you can loop signals through the projector. YUV cables represent an analog video connection with three channels. The YUV cable is of the best quality for the analog connections.

When connecting the projector, make sure that the distance to the screen is maintained correctly. If the distance is too small, you will not get the entire picture on the canvas.

 

How do you recognize a good projector?

First of all, the light intensity is crucial for a home cinema projector. Contrast and color fidelity also play a role in supporting roles. The ANSI Lumen represents the indication of the brightness. For home use, a projector with an Ansi Lumen from 1000 to 2000 is completely sufficient.

Air noise should also be considered when buying the projector. The better projectors already have dB values below 30, which can roughly be equated to a quiet conversation.

However, you shouldn’t just fix yourself on the dB specification, because the noise always depends on the housing of the projector. In some cases, 20dB can appear louder than 30dB. Therefore, a test should be done on-site before buying.

Advantages and disadvantages of projectors and televisions

A projector is a lot more versatile than television with a DVD or Blu Ray player. Not only game consoles, cameras, and PCs can be connected, but also Blu-ray, DVD, and video. Even with the gigantic size of the picture size, television has to give up. There are already televisions with very large diagonals, but they cannot keep up with a projector.

Even in small rooms, a quality image can still be created using a projector. The prices for projectors are also quite affordable. Because of their size, projectors also have an advantage over a television.

By the handy size, the projector can be easily transported from A to B, this while if television is not so simple the case.

However, a projector also has numerous disadvantages compared to television. The brightness of the device is lost in daylight, which is why good picture quality is usually only possible in darkened rooms. Projectors are also louder than televisions because the heat generated has to be removed by a fan.

Since projectors are small in themselves but require a projection surface, the question of the space problem arises. If a projector is used, you must make sure that there is at least one smooth and solid wall. In addition, high-quality cables and possibly a screen must be purchased for the projector. The replacement of the lamp is also not necessary for a television.

 

For which application area is a projector suitable?

The projector can be used in a wide range of applications.

During a presentation, it must be ensured that the projector has a certain brightness. Certain values for the Ansi Lumen are also necessary. In small rooms, which can also be darkened, devices with 1500 ANSI lumens are quite sufficient. If fonts and graphics are shown with the projector, a resolution of at least 1024 × 768 pixels should be considered.

If the projector is used for a slide show, it should be possible to reproduce the smallest possible details of images.

The SVGA projector is completely sufficient as a television replacement. It is sufficient if the pictures can be displayed in 4: 3 format. However, this resolution is no longer sufficient for films in HD resolution. To be able to see HD, you should choose the next better resolution for your projector.

In the home cinema, the projector should deliver the 16: 9 format, since most films have this format. With a format of 4: 3, you give away a good third of the picture. Better deinterlacing is also important for a projector in the home theater.

Since the video material is in most cases in fields, these are put together as full frames with the help of deinterlacing. In most cases, high-quality DVD players already deliver full images to the device.

 

Projector manufacturer

There is a wide range of projector manufacturers to be found, which can also be found in many tests.

Benq

Benq has been a market leader in the field of projectors for years. Benq projectors are often used for company presentations.

Canon

Canon offers the right projector for every situation. Whether for the classroom or private use – Canon offers projectors of every class

Casio

Casio projectors are characterized above all by their construction, which is very light. Also, these projectors are perfect for mobile use.

Epson

Epson projectors range from large to small. Also, these projectors not only have numerous additional functions but also offer a good price-performance ratio.

Kindermann

Kindermann projectors have made a name for themselves in recent years. Small and light projectors, in particular, can be found at this manufacturer.

 

You should pay attention to this when buying.

Many property owners want a video projector for carefree home cinema enjoyment. They can not only experience the latest cinema blockbusters from DVD or Bluray in brilliant quality but also use this system for television. Some have specially converted their living room and installed a corresponding canvas. Cinema enthusiasts with the necessary change have probably set up their small screening room. We would like to give you the most important points to find the right projector and the right equipment.

Since a wide variety of projectors are available on the market, the choice depends on the frequency of use, the location, and your viewing habits. In a projector test 2018, the test subjects took a closer look at the different models.

The projection technology

Many modern models now work with DLP or LCD technology. However, some of them already offer a more modern LCoSprocess. In the previous chapter, we already presented the advantages and disadvantages of these techniques. The DLP process works with micromirrors and a rotating color wheel. This technology is extremely low-maintenance and achieves fast response times.

But the LCD projectors also have a very good color intensity and ensure sharp images. The LCoS projectors are still relatively new, with almost no pixel grid, which sometimes occurs with the LCD models. In contrast, LCoS projectors can still have a slight drag effect. If you want to use a device on the move and prefer a compact device, you should look into the LED projectors’ league. However, they are not quite as bright as the previous techniques.

Each technique has its advantages and disadvantages, so you have to make compromises when making a purchase decision. The DLP and LCD projectors are recommended for interesting price-performance ratios.

The luminous flux

In earlier times, video screenings were only possible when the room was completely darkened. We can only recommend you choose a projector with a light intensity of well over 1,000 lumens. This is particularly necessary if the video projector is also to be used in very bright rooms.

The lamps

The lamps of video projectors are also a criterion for many customers when making a purchase decision. Gas discharge lamps are still used in most models. These tend to lose light output after a while. Manufacturers specify a lifespan of between 2,000 and 5,000 hours.

It should not go unmentioned that replacement lamps can sometimes cost up to 300 euros. A tip for a purchase decision is that you should not only pay attention to these lamps’ long lifespan but also take a look at the compatibility list to be able to use cheap replacement lamps. This is particularly important if you want to use your projector intensively.

Some video projectors have a so-called ECO mode, with which the luminosity of the lamps can be reduced, and at the same time, the service life is increased. So check which lamps are installed in a projector.

Mobility Needed?

If you want to use a video projector on the go, for example, for presentation purposes, then you should pay attention to compact dimensions and low weight. As a rule, LED projectors offer exactly the right conditions. It is quite practical if speakers are also built-in to do without an elaborate sound system.

Canvas or white wall?

What good is the best projector if it cannot align its performance with a suitable projection surface? Many buy an expensive projector and are disappointed with the result afterward because they have saved on a screen.

Especially if you use a full HD projector, you should buy a good screen. This is the only way to reproduce brilliant image results. For occasional use, it is also sufficient if you use special wall paint. There are reflective wall paints on the market, such as ProFlex Base White, which can be applied to any smooth wall surface after the previous priming.

 

Advantages when buying on the Internet

On the Internet, it is easier to compare functions and prices and use models to take a closer look at the models. In most cases, projectors can be bought on the Internet at much lower prices than in the shop.

Optimally adjust the projector.

After you have bought the projector of your choice and installed a suitable screen, you face another problem. How is a projector set up optimally?

First of all, it depends on the location of the projector. Should this be set up on a separate table, or should it rather be mounted on the ceiling? Both variants offer advantages and disadvantages. Not everyone can do such an installation on their ceiling. It is easier to set up the projector separately. Some living room tables offer a practical compartment from which the video projector can display its image on a screen at a slight angle. Of course, professionals will try to mount the projector on the ceiling.

My picture does not fit on the canvas!

Many customers are aware that they have problems with the image display after installing their video projector. The playback picture is larger than the canvas, much too small, distorted, or crooked on one side. The orientation and distance play an important role here.

If you want a real cinema feeling, the screen must be half the width of your seat from it. For example, if you sit five meters away from her, it should ideally be 2.50 m wide. If the image is much larger or you are too close to it, the playback image may appear blurred. With a width of 2.50 m, your projector should also be at a distance of 2.80 to 4 m from the screen. However, these values depend on the zoom setting of the lens.

The projector is being prepared.

You should take the following tips to heart to achieve a sufficiently good reproduction quality:

  1. First, you should align the screen straight. Take a spirit level with you. Then place your projector horizontally in front of the screen in the middle.
  2. Now connect your projector to the socket and switch it on. Don’t forget to remove the lens cap. You will laugh, but many customers have complained about their video projector without knowing that this cover has to be removed beforehand. After a few seconds, a manufacturer-specific image appears on the screen, focusing on using the front lens zoom ring.
  3. You can now call up the main menu using the projector’s remote control. Look for the so-called keystone correction or keystone correction here under the image settings. You should set this to neutral, which is usually represented by an optical sliding bar. For initial alignment, completely screw the feet of the projector into the housing.
  4. Then use the wheel near the lens to adjust the lens shift in the middle. This requires a little practice, and the center position can be roughly estimated by turning in both directions.

Set the zoom correctly

The projected image on the screen can be easily adjusted using the built-in zoom lens of the projector. This special lens has the advantage that you do not have to move your projector closer to the screen or further away.

For normal living rooms, the average distance between the video projects and the screen should be around 3 to 3.50 m. The models presented here in our projector comparison of 2020 can all be used without restriction.

We stop lens shift

The lens shift is particularly important for a projector. For example, if we set up the video projector to the side or at a height from the projection surface, the lens shift will display the image in the center of the screen without further loss of quality. The lens shift is adjusted using a small joystick or wheels that are close to the lens.

Many modern models are designed in such a way that their projection image is slightly radiated vertically upwards. In this way, you can conveniently place the projector on a table and look over it. The playback picture is still displayed at eye level. You should only be careful when removing the installation site. The further the video projector is from the screen, the higher the image moves.

Correctly display distorted images using keystone correction.

If, for example, you cannot place a projector in the middle of your screen and, for example, it throws its projection image onto the screen at an angle from above, this can result in image distortion. The picture above is often wider than below. It looks trapezoidal.

You can find the keystone correction via the image settings menu. This can be set manually using the integrated buttons on the projector or using the remote control. If the images are shown are wider or narrower at the top or bottom, we speak of vertical keystone correction. If the images on the left or right are of different heights, then this is horizontal keystone correction.

With such a correction, the playback image shrinks a little so that you can bring it back to the desired size using the zoom setting on the lens. It should not be left unmentioned that such a setting decreases the sharpness a little. We, therefore, recommend that you, if possible, set up your projector parallel to the screen.

Adjust color and sharpness

First, let your projector warm-up for a few minutes until the lamp has adjusted to its operating temperature and brightness. When used for the first time, the colors may appear somewhat unnatural. As explained earlier, the video image in projectors consists of the three primary colors blue, green, and red. Depending on the model, these colors can also be set individually. We only change the values in small steps so that we can control the effects directly. A strongly saturating color setting, in turn, leads to images that appear very unnatural.

Some manufacturers can order free test files or even test DVDs on the Internet, with which we can adjust the image more precisely using color bars. But even without this help, we can achieve very good color matching. For this purpose, we should only use real black and white reproduction. We are most likely to notice a possible color cast.

If we use a wall instead of a screen as a projection surface, we can precisely adjust the background using the color setting. This is always necessary when our wall is not completely white. If the projection surface contains a slightly yellow tint, we have to reduce the colors red and green. In this way, we compensate for the yellow of the projection screen.

Now the sharpness is regulated.

The image sharpness of a projector is regulated directly on the lens. We must make sure that we can see the entire projection area. If you have the option, you can use a geometric pattern. With the test mentioned above DVDs, there are various grid lines on a black background that we can use.

All grid lines should be the same size. Furthermore, the grid shown should, of course, not appear blurry. A special fine adjustment is necessary here.

Some modern video projectors also have an automatic focus control. The image is focused on using control electronics. However, we cannot always rely on such an automatic system, as ghosting can also be made visible by increasing the focus if the automatic lower the focus setting, the images can also appear soft and washed out. Manual readjustment is still necessary here too. With our projector comparison winners, you can change the sharpness both automatically and manually.

After all these settings, you can sit back and enjoy your first feature film on your own projector.

 

Useful accessories

A great cinema feeling cannot be achieved with a good projector alone. Rather, we should also take a look at practical and useful accessories. We would like to give you a few examples below.

The video screen

A good screen is essential for an excellent video display. If you want to get one, you should prefer a 16: 9 model. Most blockbusters really come into their own in this format.

The gain factor also plays an important role. This factor represents the reflective properties of the canvas. Usually, this should be between 1 and 1.2. If you look closely at a canvas, you will notice that it has a light grain that consists of this reflective layer.

In addition to the stationary screens that are placed on the wall or under the ceiling, mobile screens are provided with a tripod or side stands. These are the ideal choice if we want to use our device on the go. With the stationary screens, the framed models guarantee that the projection surface remains flat and even for a long time.

The sound system

What good is the most beautiful picture if the sound is miserable. For this reason, only a powerful surround system can be recommended for high-quality cinema enjoyment. The correct distribution of the loudspeakers and a bass woofer (subwoofer) gives you the impression of being right in the middle of the film.

Modern surround systems are sometimes even offered with a wireless connection. Make sure that the DVD or Bluray player also has such a WiFi connection. Depending on the projector model, the image transmission can also be transmitted via Wifi.

3D glasses

Cinema films are increasingly being offered in 3D. In conjunction with a 3D-capable Bluray player and a 3D projector, these films can also be viewed at home. To be able to experience these performances up close, we recommend 3D glasses with appropriate polarization filters. 3D shutter glasses are offered in many different designs. Some of them are already included in the scope of delivery of a 3D projector.

Transport case

Many projectors are used on the go. It doesn’t just have to be the compact LED models. To ensure safe transport, we recommend using a sturdy transport case or a padded transport bag for a projector. These cases are designed precisely to the dimensions of the housing and also keep out bad impacts as well as dirt and moisture.

Visualizer

Some manufacturers offer a so-called document visualizer, especially for the wired but also wireless connection to a projector. This is a small camera that scans documents and images and then forwards them to the device. In this way, for example, annual reports can be presented directly on a screen. The principle is similar to a traditional daylight projector.

The useful little helpers

In order to be able to operate the models presented in our projector test reliably, numerous third-party providers have corresponding projection tables that can be individually adjusted in height. Furthermore, numerous ceiling fixings are also offered for ceiling mounting, so that a projector can be securely fixed there.

External companies offer numerous products for cleaning and maintaining a beamer. In this respect, we would also like to mention the lens cleaning wipes and housing cleaning wipes.

So-called wireless dongles, which can be plugged directly into the USB port of a projector, are also popular. They enable wireless data transmission between a PC and the projector. But video content can also be transmitted wirelessly.

With the help of an optional MHL adapter connected directly to the HDMI input of a projector, it is possible to connect a smartphone to the projector. This even achieves full HD quality. With such an adapter, a smartphone’s display content can be projected directly onto a screen using a projector.

Finally, special remote controls replace the original remote control of a projector and contain a laser pointer for presentation purposes. However, these presentation aids are of less interest for private use.

Statistics, numbers, data, and facts about the projector

For our projector comparison, experts test.de would like to disclose a few basic statistics that may be of interest.

Based on the source of the statistics portal Statista, we were able to determine that buying interest for a projector has increased slightly in recent years. In 2013, around 2.09 million customers were interested in a projector. In 2014 the figure was 2.16 million. It is also interesting to note that in 2013 around 4.05 million were the owners of a projector, compared to around 4.11 million in 2014.

The interesting data of today’s projectors also include the approximate service life of the built-in lamps. LED projectors achieve the longest lifespan with at least 20,000 hours. The lamps of LCD and DLP projectors usually last between 1,000 and 5,000 hours.

We would like to go into the projection ratio in our projector comparison. When operating a projector, it is important to know the distance between it and the projection surface. As the distance is reduced, the image to be displayed also becomes smaller, while the image is enlarged when enlarged. The following formulas are required to determine the projection ratio:

Format 16: 9:

  • The focal length of the lens in cm/chip size x 1.15

Format 4: 3:

  • The focal length of the lens in cm/chip size x 1.25

Alternatives to the projector

Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.For a professional large-screen display for film screenings or presentations, there are also interesting alternatives to a projector, which we would like to mention here in conclusion. We would like to say in advance that a real cinema feeling in a practical test could only come up with a projector.

The large-format displays

Large-format displays, or LFDs for short, are large format flat screens used for presentations in schools, universities, and conference rooms. They are used more and more often than conventional projectors. However, these displays are still very expensive to buy and are, therefore, hardly worthwhile for private use. Nevertheless, we would like to briefly discuss the advantages.

  • LFDs produces razor-sharp images even in backlight conditions
  • the speaker is not blinded during lectures,
  • This background display means that people passing by can no longer cast annoying shadows,
  • there is no noise from fans,
  • LFDs are immediately ready for use and do not have to run after switching off,
  • the displays are maintenance-free, so there is no need to change the lamp,
  • LFDs are more energy-efficient,
  • there is hardly any radiation heat generated,
  • the design resembles a modern flat-screen TV,
  • in contrast to the complex ceiling installation of a projector, an LFD only has to be attached to the wall and
  • there are even models with modern touchscreen technology so that LFDs can also replace the old school blackboard.

Modern plasma, LCD or LED flat-screen televisions

Today’s flat-screen televisions with a minimum size of 50 inches should not go unmentioned. In the meantime, there are already models with a size of 110 inches that have a screen diagonal of 2.5 m. They offer ultra-full HD resolution, in which the individual pixels on the image surface are almost invisible.

In general, today’s flat-screen TVs convince with very good color brilliance and sharpness. Regardless, the individual technologies, such as plasma, LCD, and LED, have certain advantages and disadvantages. The main reason that speaks for a flat-screen TV is, of course, the now affordable purchase price.

Rear projectors

Rear projectors offer a screen diagonal of around one meter. The devices are characterized by a very heavyweight. The reason for this is that a video projector is integrated into the voluminous base. The latter projects his image through a mirror onto a screen. Rear projectors are no longer recommended today because they have a major loss in color brilliance, contrast, and sharpness.
