What is an HD projector?

A projector, also a video projector or digital projector, is a device that projects moving and still images from a visual output device onto a screen enlarged. Output devices can be computers, televisions, DVD players or video recorders. The term projector is derived from the English word beam.

HD or HDV stands for High Definition Video and means high-definition video. HD is currently the highest level of development in video technology. The HD projectors that range from small, mobile projectors to stationary high-performance projectors for movie theatres.

 

How does an HD projector work?

The HD projectors, there are different technologies.

DLP

The abbreviation DLP stands for the Digital Light Processing method. The image is created by millions of tiny mirrors that project the light onto the screen. Each of the mirrors represents a point of light. Due to the fine mirror structure, an image without screening is possible. Areas of application for DLP projectors are the business area and home cinema for beginners.

Advantages:

  • Small and compact
  • High contrast
  • Fine font and line drawing
  • Durable DMD chips
  • Low maintenance

Disadvantage:

  • Possibly. audible colour wheel
  • Rainbow effect (slight flashes of colour can be seen)
  • Not perfect colour fidelity

LCD

LCD means Liquid Crystal Display. The white light from the projection lamp is created by the additive colour mixture of the three primary colours red, yellow and blue. The technology works with liquid crystals that project the image. LCD projectors are ideal for sophisticated home cinema.

Advantages:

  • Fine pixel delimitation
  • High quality, colour-true images
  • A bit brighter than the DLP technology

Disadvantage:

  • Weak black level
  • Flyscreen effect possible at low resolution
  • Maintenance required (filter change)

LCoS

LCos (Liquid Crystal on Silicon) is a technology from Canon. Different manufacturers use different terms for the same procedure. JVC refers to it as D-ILA (Direct-Drive Image Light Amplification) and Sony as SXRD (Silicon X-tal Reflective Display). All three technologies work in the same way, with the panels reflecting the light instead of transmitting it, as with the DLP technology. LCoS combines all the advantages of the DLP and LCD processes. HD projector and is ideal for demanding home cinema.

Advantages:

  • High resolution
  • Good contrasts
  • No-fly screen effect

Disadvantage:

  • Low lumen output
  • Relative expensive

Advantages & application areas

There are three areas of application for an HD projector :

  • presentations
  • Home theatre
  • Gaming

Advantages of HD projectors in detail

When choosing between a television and HD projector, the application is crucial. Do you only watch TV from time to time, or are you a real home theatre lover who wants to experience films in the best possible quality? Do you want to watch films during the day or only in the evening?

Image size

Television can only present the picture in one size. With an HD projector, you determine the image size yourself. Only with a large picture can you immerse yourself in a film.

The large image area of the projector image creates a real cinema atmosphere. Especially with 3D films, the film experience is more intense with a large projector image.

Luminous intensity and ambient light

Another important point is the ambient light. The brighter the room, the higher the light intensity of the projector. However, this is at the expense of contrast. For the operation of a projector, it is optimal if the room can be darkened. In this way, you can achieve a bright and high-contrast projection image at any time of the day. On the other hand, you get a good picture on a TV around the clock.

picture quality

The picture of an HD projector is higher quality than that of a TV of comparable size. The projector image also convinces with the natural reproduction of the colours and strong contrasts. With the HD projector, the light is reflected off the screen, while the television works with self-illuminating pixels.

The human eye perceives the image from the HD projector as much more pleasant. In the darkened home cinema, contrast and colours come into their own particularly well.

installation

Today TV screens are quite thin, but sometimes also very large so that they take up a lot of space in the overall picture of the room. The projector and the screen are easier to hide and are therefore less dominant in the spatial image. The projector can be mounted unobtrusively on the ceiling, and a tripod or roller screen can be hidden well during the day.

Connectivity

Most HD projectors have several digital and analog connections. The main ones are DVI and HDMI. If you want to use different players such as Blu-ray players, satellite receivers and a game console, you should use an AV receiver. With the help of HDMI radio systems, the signals can be routed wirelessly.

Conclusion

For those who attach great importance to the largest possible film image, the HD projector is the right choice. You can only experience a big cinema with an HD projector and screen. The darkening of the home theatre room can be easily done with curtains and blinds. However, if you want to switch on the device at brightness, a TV set offers better properties. However, with a projector for a comparable price, you get a much larger screen size and very high-contrast and natural colours. Compared to a TV screen, the HD projector offers many advantages, especially for home fans.

 

What types of HD projectors are there?

The HD projectors on the market differ mainly in their different technologies.

  • DLP
  • LCD
  • LCoS
  • LED

DLP

The DLP technology was developed by the US company Texas Instruments. The DLP projector creates moving images by modulating them onto a light beam. The projection beam is broken down into individual pixels by a large number of movable micromirrors and reflected pixel by pixel into the light beam or out.

The heart of the technology is the matrix, a component in which the mirrors are arranged in a square. The generic term for this matrix is DMD – Digital MicromirrorDevice, German: digital micromirror unit.

With this method, the image is not imaged optically but only created in the projection beam. The light is divided into the basic colours, which then hit the screen one by one. The picture is created only in the eye of the viewer.

There are DLP projectors with one chip technology and devices with three-chip technology. The latter is much better and more expensive. DLP projectors are also used in cinemas.

advantages

  • High black level
  • Very good 3D quality
  • No streaking
  • Soft grid
  • High contrast
  • Little dust generation

disadvantage

  • Rainbow effect (flashes of colour) possible
  • Colour fastness sometimes insufficient
  • Loud fan noise

LCD

An LCD projector works with liquid crystals. The white light from the projector lamp is divided into three basic colours using a prism. The light is then sent from LCD panels and finally projected through another prism as a colour image.

LCD projectors can display very fine gradations between light and dark. The colours look strong. The LCD technology shows weaknesses in the black level of the video image, which is displayed less saturated.

advantages

  • Fine pixel delimitation
  • High colour fidelity
  • Lightweight
  • Strong contrasts
  • Inexpensive
  • Good readability

disadvantage

  • LCD memory effect
  • Flyscreen effect possible
  • Weak black level
  • Maintenance required (filter change)

LCoS

The abbreviation LCoS stands for Liquid Crystal on Silicon and means in German about liquid crystals on silicon. LCos technology works similarly to LCD technology. However, the light is not let through here but reflected.

A polarized light beam hits the molecules of liquid crystals. A chip aligns the molecules using electrical voltage. This allows the chip to determine the intensity with which the light is reflected.

There are LCoS beamers with one or three chips. With 3-chip technology, the light of the primary colours is divided by dichroic mirrors. The reflected rays are then brought together again by a dichroic prism and finally projected onto the screen.

With an LCoS projector with only one chip, the light comes in the basic colours of LEDs. They initially split light is reunited by dichroic prisms, and it hits a polarized beam splitter. The beam splitter guides the light to the LCoS and at the same time also the light that is reflected from the LCoS to the projection lens. LCoS projectors with one chip technology work similarly to a DLP projector, since LCoS reflects the light of the primary colours one after the other.

The advantage of the one-chip systems with the LCoS projectors is their compactness. A projector with this technology fits in your pocket. For demanding home cinema fans, projectors with 3-chip technology are more interesting because they produce outstanding picture quality.

Depending on the manufacturer, there are different names for the LCoS technology. For example, Sony has an SXDR projector. Sony has a patent for SXDR technology. The SXDR system is essentially based on LCoS technology. The situation is similar for D-ILA projectors from JVC.

advantages

  • High resolution
  • Very high contrast
  • Very good black level
  • Very good 3D ability

disadvantage

  • High price
  • Low brightness

LED projector

LED stands for Light Emitting Diode and means something like a light-emitting diode. LED projectors use either LCD or DLP technology. The special thing about the LED beamers is that instead of using a UHP lamp, they work with LED lamps that generate the light of the three primary colours. LEDs are much smaller, lighter and more energy-efficient. They also produce less waste heat than a conventional lamp. Another big advantage is the long lifespan of the LEDs. A UHP lamp only lasts about 5000 hours of operation, LEDs on the other hand, they have a lifespan of around 30,000 hours and more. Every lamp replacement ultimately incurs follow-up costs.

advantages

  • Little weight
  • Long lifetime
  • Little power consumption

disadvantage

  • Low light output
  • Low colour fastness
  • Low brightness

This is how HD projectors are tested

Here you will find everything you need to assess the HD projector in the product test. We explain the most important criteria and terms relating to the subject of HD projectors. In this way, you can better understand and assess test results and product descriptions.

Light output – ANSI lumens

To display a beautiful, sharp and high-contrast image, the projector must have good light output. The light intensity is measured in the unit of measurement ANSI lumens. Also, the image quality depends on the lighting of the surroundings.

The brighter the home theatre room, the higher the light output must be. Projectors with high luminosity can also be used in bright rooms.

1800 ANSI lumens are sufficient for a room that can be completely darkened. If the room cannot be completely darkened, at least 2000 ANSI lumens are required.

Basically, the greater the distance between the projector and the screen, the more light output is needed. Projectors with more than 3500 lumens are particularly suitable for large, not entirely dark rooms.

contrast

In addition to the light output, the contrast value is also responsible for good image quality. The contrast ratio describes the difference between the brightest and the darkest point within the video image. The ambient lighting also affects the contrast value.

If an HD projector with a high light output is used in a bright room, good contrast values are achieved. When used in a dark room, the contrast also improves with a high-speed projector.

To be able to project in good image quality, the projector should offer a contrast ratio of at least 5000: 1. A higher contrast ratio of around 40,000: 1 is recommended for gaming and home cinema. From a contrast value of 100,000: 1, the projector delivers top performance.

resolution

Another important aspect that you should consider in a product test is the resolution. The layout of an HD projector, like a screen, has the shape of a grid. With a FullHD resolution of 1920 x 1080 pixels, the grid has 1920 columns and 1080 lines. The more pixels there are, the higher the resolution and the better the image quality. In the meantime, FullHD has become the standard for films on Blu-ray from streaming providers.

For home cinema, you should choose a Full HD projector. Even if you want to use the projector for presentations, you should opt for a high resolution, since most laptops today also have a Full HD display. Projectors labelled HD Ready, or 720p is not HD devices. UHD or UltraHD

projectors have a resolution of 3840 × 2160 pixels. They are ideally suited for home cinema.

If you have particularly high demands on image quality, a 4K projector is a right choice for you. 4K projectors have a very high resolution of 4096 × 2160 pixels. This means that you are also prepared for future developments. 4K projectors offer the best technology currently available. With some devices in the product tests, there is also the indication 4K enhancement. These projectors use technologies to improve the image quality, e.g. B. Pixel shifting.

The contrast can be significantly improved with the HDR process (High Dynamic Range). However, not all projectors are equipped with HDR.

3D

3D films are becoming increasingly important. The 3D projection offers a perfect, innovative and exciting film experience. The important factor for an impressive 3D projection is the refresh rate or refresh rate, which is given in Hertz (Hz). The higher the frequency, the clearer and more brilliant the video images are.

Quite good results can be achieved from a frame rate of 120 Hertz. For home theatre and gaming, the refresh rate should be at least 240 Hertz. For particularly demanding home cinema fans, it should be at least 480 Hertz.

Connectivity

There are analog and digital connections. Analog connections include YUV, S-Video and VGA. They are used to connect older devices, such as video recorders.

The most important digital connection is HDMI, in which sound and image are transmitted simultaneously. The HDMI connection is standard on modern devices.

A DVI connection can be used for both analog and digital image transmission. With DVI, a signal can also be adapted and brought to HDMI quality.

An HDMI connection is completely sufficient for occasional home cinema users. In the business sector, the variety of connection options is an important aspect. Here the projector is used by various customers and partners. One only has a VGA connection. The other needs a USB connection. The projector should have a USB port for data transmission.

 

What should I watch out for when buying an HD projector?

LCD and DLP, Full HD and WUXGA, ANSI lumens, and lens shift? – The world of HD projectors is full of question marks for beginners. ExpertsTesten.de helps you find your way in the jungle of technology and ultimately make the right purchase decision. We have summarized the basics of the latest technical developments understandably and clearly.

Area of application – For what purpose would you like to use the HD projector?

You should differentiate whether you want to use the HD projector in the home cinema, for playing or in the business area.

HD projector for the business sector

In the business sector, the projector is mostly used in a bright environment. Therefore, a high light intensity of at least 3,000 ANSI lumens is recommended. A contrast ratio of approx. 3,000: 1 is sufficient in daylight.

FA, a legible display of text and graphics, requires a WXGA resolution of 1280 x 800 pixels. WXGA is particularly suitable for a projector that is connected to a laptop with a widescreen format. A full HD projector with 1920 x 1080 pixels is an even better choice. Full HD enables a very high-quality display of videos and graphics.

The projector is often used in different rooms and should always offer a good picture in different lighting conditions. For mobile use, the device should be quick to assemble and disassemble and have as many different connections as possible.

When using a projector stationary in a seminar or conference room, the room’s size and the optimal distance from the screen must be taken into account.

HD projector for home cinema

At home, HD projectors are becoming increasingly popular as home cinema projectors. Together with a good hi-fi system and a large screen, an HD projector offers first-class film experiences. You should pay particular attention to the picture quality, i.e., to high light intensity and good contrasts, when buying a projector for the home cinema. Also, the device should be 3D-capable. The correct distance between the projector and the screen is also important.

Gaming projector

As in-home cinema, the right distance to the projection screen, 3D capability, the right lighting conditions, and the light intensity also play a major role.

format

For home cinema, HD projectors with the format 16: 9 are ideal. Most current films are designed for the 16: 9 format. For the 16: 9 format, a resolution of at least 1280 × 720 pixels is required. Full HD projectors can project in a high resolution of 1920 × 1080 pixels.

If you value a higher resolution, you should opt for a 4K projector with a resolution of 3840 × 2160 pixels. However, 4K projectors are more expensive than conventional HD projectors. Some high-quality full- HD projectors offer 4K upscaling, for example, 4K enhancement technology.

If you want to use the projector for business presentations, an SVGA resolution of 800 × 600 pixels is sufficient.

A good HD video projector should be 3D capable. Another interesting feature is the intermediate image calculation (frame interpolation) for 2D and 3D. It creates a fluid image, even with fast movements.

Resolution – HD ready, Full HD and 4K

Resolution is the number of pixels in an image. The higher the density of the pixels, the sharper the image. Full HD is the name for Full High Definition, the full high resolution of the image. Full HD projectors have a resolution of 1920 × 1080 pixels and are designed for a 16: 9 aspect ratio. Projectors with the HD Ready 1080p label only have an approximately half lower resolution of 1280 × 720 pixels and can also project in 16: 9 format.

How high the resolution should be with your HD projector depends above all on the application and the image source. To get started, a resolution of at least HDready is advisable. An HD ready projector (1,280 × 720 pixels) ensures a sharp picture. The film experience with a Full HD projector (1,920 × 1,080 pixels) is even more impressive. A Full HD device is also the right choice for gamers.

For the upscale home cinema user, there are 4K projectors with a resolution of 3,840 × 2,160 pixels, which, however, also have an upscale price.

Image quality: contrast and light intensity (ANSI lumens)

The contrast is the maximum difference in brightness between white and black. If the contrast ratio is 1,000: 1, the brightest point of the image is 1,000 times brighter than the darkest point. The higher the contrast value of a projector, the more natural and sharp the picture. High contrast is also important to produce a deep black.

The contrast values your HD projector should have depended on the area of application and the brightness of the surroundings. In dark rooms, a high-contrast HD projector can reproduce very natural and vivid colors. If the projector is mainly used in daylight or artificial lighting, the contrast is less important.

The contrast ratio of your HD projector should be at least 5000: 1 and higher, ideally 10,000: 1. This ensures the optimal display of colors and gradients.

The light intensity of a video projector is specified in ANSI lumens and indicates how much light the projector can project onto a surface. The ideal light intensity for your HD projector depends on the spatial conditions. The brighter the ambient light, the stronger the projection light must be. Other factors are the projection distance and image size. The greater the distance, the brighter the projection light must be.

If the space in your home cinema can be completely darkened, around 1,500 ANSI lumens are sufficient. However, if there is a lot of ambient light in your home cinema, the projector should have at least 3,000 ANSI lumens.

Image shift

If the projector is not placed exactly in the middle of the screen, it will be distorted. The image can be rectified using the lens shift function. It is ideal if the lens can be adjusted in height (vertical) and sideways (horizontal).

zoom lens

With the zoom lens, the image can be reduced and enlarged. This allows you to adjust the image exactly to the size of the canvas. The larger the zoom range, the greater the scope for the projection distance. If the projector does not have a zoom lens, it must be moved back and forth until the picture fits the screen exactly.

Noise level

The higher the light intensity, the hotter the projection lamp gets, and the ventilation has to work more and gets louder. Ideally, the noise level should be below 35 decibels. Some models are equipped with an eco or whisper mode, which lowers the noise level.

Ceiling mounting or mobile use?

If you choose the ceiling mounting, your projector should have a mounting hole and a vertical and horizontal image reversal function.

Weight plays a major role in mobile use. Mobile projectors should not weigh more than three kilograms. Internal speakers are also practical. If the sound quality is not sufficient, you can use external speakers.

connections

A general distinction must be made between digital and analog interfaces. The best quality is achieved with HDMI and DVI connections that transmit digital data without loss of quality. A YUV video input should also be available for projecting analog image media. S-Video and Composite (FBAS) connections are required for an analog video recorder or satellite receiver. The signals are transmitted from the computer to the projector via the DVI or VGA interfaces.

You need a USB to play presentations from a USB stick. For optimal flexibility, the WiFi capability of the projector is recommended. If you want to connect an MHL-compatible smartphone or tablet, you should purchase an MHL-compatible projector.

Functions

A good HD projector should have the following features :

  • Keystone correction
  • Lens shift
  • Optical zoom

Keystone correction

Keystone correction, also known as keystone correction, compensates for unwanted trapezoidal distortions in the image.

Lens shift

This function is used for distortion-free vertical or horizontal alignment.

Optical zoom

An optical zoom ensures flexibility when projecting. Even if the distance between the projector and the screen is not optimal, the image can be corrected.

All in all, buying on the Internet has many advantages over buying a projector in a specialty store. Informative test sites help you to find the right HD projector for you.

 

Interesting facts & advice

The history of the HD projector

Film projector

The forerunner of the video beamers was the film projector, with which films were projected onto a screen. A film projector usually runs at 24 frames per second. Home cinema projectors for Super 8 films run at 18 frames per second, television films at 25 frames per second.

Super-8 footage was available for home theatre. Professional films or feature films were shot on 16 mm or 35 mm film. Film projectors were unrivaled for around a century. Since the turn of the last millennium, professional films and private videos have been increasingly produced and screened digitally. This was associated with a comprehensive changeover to digital film projection.

Video projector with eidophore system

The video projection process began with the Eidophor system, developed in Switzerland in 1939, the first process to project television films over a large area. The technology was still used in the professional sector until the late 1980s. The term eidophore comes from Greek and means something like image carrier.

Tube video projector

The very first video projectors were equipped with three cathode-ray tubes and three separate lenses, one for each basic color. The larger the tubes, the better the brightness and resolution of the picture. The electron beam was generated either ES (electrostatic) or EM (electromagnetic). Due to the low brightness of the picture, the room had to be completely darkened when projecting tubes.

Adjusting the tubes required a complex and lengthy set-up procedure that could only be performed by experts. Also, the devices were very heavy and hardly suitable for mobile use.

LCD and DLP video projectors

In the next generation of video projectors, the first LCD and DLP video projectors were launched in the 1990s.

Figures, data, facts about the HD projector

Operating costs / electricity consumption

When buying a projector, note what follow-up costs, e.g., for replacement lamps to come to you. The price of a projection lamp is between around 35.00 and 350.00 euros. The lifespan of a lamp is usually between 2000 and 8000 hours. In the case of mobile models, the lifespan of the lamp is considerably shorter at 1000 to 4000 hours.

If you want to keep the projector’s operating costs low, you should opt for an LED projector whose lamp can last up to 20,000 hours.

 

Assemble the HD projector correctly in 10 steps

Step 1: Choose the correct distance from the screen

Read the operating instructions from the manufacturer of your projector or calculate the optimal distance from the screen yourself. As a rule of thumb, the width of the screen should be half the distance between the viewer and the screen. So if your couch is four meters from the projection surface, the screen should be around 2 meters wide.

So you can calculate the optimum distance for yourself: Go to the website beamer hop.de and then select the manufacturer and model of your projector. If you already know the size of your canvas, click the “Size” tab. Here you must first select the format 16: 9 and 4: 3 and then specify the width of the canvas. Now confirm the information with the Enter key and read the minimum and maximum distance. If you only know the distance from the projector to the screen, click on the “Distance” tab and enter the distance between the projector and the screen.

step 2: Suitable pad

Place the projector on a firm surface, e.g., B. on a table.

 

step 3:Align the projector

Most devices have adjustable feet that allow you to align the projector individually. When aligning a projector, the device should be placed as parallel as possible to the lower edge of the screen. In the case of ceiling mounting, it is best to align the projector parallel to the top edge of the screen. If the projector has an offset function, the image starts slightly higher, and the device should be placed slightly below the lower edge or slightly higher than the upper edge of the screen. You can make small corrections to the image using the keystone correction. Please note the information in the operating instructions.

 

Step 4:Lay the cable safely

Lay the cables in such a way that there are no trip hazards.

 

Step 5:Ceiling and wall mounting

If you want to use the projector more often, it makes sense to mount it under the ceiling or on the wall. Once the projector is assembled and set up, you don’t need to readjust it every time. Further advantages are that the cables can be laid on the ceiling or wall, the video beam is free, and this variant saves space. It is best to attach the projector with the bottom up. On the underside of the device, some projectors have a 1/4-inch thread for screwing onto a photo tripod. If this thread is not available, you need a projector holder.

 

Step 6:Settings

The fine adjustment of sharpness can be made on the lens with the ring in front. If the projector has a lens shift function, you can use it to adjust the image up or down until it fills the screen exactly. You can compensate for wallpaper distortion with the ” Keystone ” or ” Keystone correction ” functions.

 

Step 7:Connect to a TV

You can connect a television for digital or satellite reception via the video output. If you want to use the Scart output, the projector should either have a Scart input or you use a Scart adapter. You can connect the TV’s audio outputs to your stereo system. The television receiver must be switched on during the projector demonstration. You can also use a video recorder as a TV receiver and connect the projector to its video output.

 

Step 8:Connect to a laptop

Here it depends on the connections of the devices. If both devices are equipped with an HDMI connection, you can use an HDMI cable. If this is not the case, you must put the appropriate adapter in between. Plug the HDMI cable into the corresponding socket on the projector and the monitor connection on the laptop. If the projector has a VGA connection, you need an adapter HDMI to VGA. You can also connect the laptop and projector via the USB ports.

 

Step 9:Connect to a DVD or Blu-ray player

The best picture quality is achieved when you connect beamers and DVD or Blu-ray players with an HDMI or DVI cable. You can also connect the player to the projector via the scart output. To do this, the projector must also have a scart connection or scart adapter. Analog connections, e.g. with a video recorder, you can produce component video, S-video, or video via the connections.

 

Step 10:Connect speakers

Every HD projector has internal speakers. However, these are far from sufficient for real home cinema enjoyment. If you are using a laptop or computer as a source, you can connect external speakers here. When watching TV on the screen, you can use the speakers on your TV or connect it to your stereo.

 

Care tips

So that you can enjoy your projector for a long time, you should take good care of it and clean it. You should take action at the latest when blurring or dark spots appear in the picture. You should treat the lens and the projector lamp with special care. Read here how to take good care of your projector.

Tip 1:Protect from dust

If the projector is not in use, you should keep it in a dust-free and protected place, e.g., in the protective cover in a cabinet.

Tip 2:Remove dust

Dust your projector regularly with a dust collector cloth.

 

Tip 3:Clean the lens

If the lens is dirty, blurring and unwanted shadows occur. Always put the lens cap on the lens of your projector after use.

Great care must be taken when cleaning the lens so that the sensitive glass is not damaged by dust particles or unsuitable cleaning agents. Remove the dust with a fine, soft brush. You can also use a special lens pen designed for this purpose. Corrosive, harsh agents and glass cleaners are taboo at this point. It is better to use warm water and a little washing-up liquid or a microfiber cloth.

 

Tip 4:Maintenance of the lamp

The lamp is the most expensive wearing part of an HD beam. Depending on the manufacturer and load, the service life is between 2000 and 8000 hours. The more often and longer the projector runs, the shorter the lifespan. Some devices have an eco mode that protects the lamp and reduces power consumption by adapting the brightness to the surrounding light. This can significantly extend the life of the projector lamp. The cost of a new lamp is between 50 and 200 euros.

 

Useful accessories

canvas

A screen with a black border is recommended. The format should correspond to the format of the image output of the projector : 16: 9 or 4: 3. You can calculate the optimal screen size as follows: Screen width = half the distance between the viewer and the screen. So, if you sit four meters away from the screen, the screen’s width should be two meters.

You can calculate the height of the canvas as follows: From the lower edge, about one meter above the floor, to the attachment point on the ceiling.

The gain factor indicates the extent to which the screen focuses the light. A gain factor of 1.0 to 1.2 is recommended for a home cinema screen. In addition to the black frame, a black, opaque rear wall is also advisable.

There are three different types of screen for home cinema :

  • Frame screens
  • Roller screens
  • Tripod screens

Frame screens can be stretched perfectly and offer the best picture. However, they are relatively expensive.

Roller blinds are very practical and cheaper. They should be left hanging for a long time, especially at the beginning. Otherwise, they could form waves at the edges.

Tripod screens are also available at reasonable prices. They can be quickly assembled and disassembled. Here, too, wave formation can occur at the edges.

Projector bracket

You can mount your projector on the ceiling or the wall. The bracket is screwed to the underside of the device and mounted on the wall or ceiling. Some models have a screw thread for a photo tripod.

Good tone

Only the right sound makes the home cinema experience perfect. The internal speakers of a projector are not sufficient for this. We, therefore, recommend the use of external speakers and a Dolby Digital or DTS-AV receiver.

 

Questions and answers about the HD projector

What does DLP mean?

DLP stands for digital light processing technology. At the heart of the DLP projector technology is a DMD chip (Digital Micro Mirror Device), an electronic component with millions of micromirrors. Each mirror creates a pixel; together, you create the video image. The longer a mirror is in the projection beam, the brighter the pixel appears.

What does LCD mean?

LCD is short for liquid crystal display. An LCD projector initially splits the light from the lamp into the basic colours red, blue and green, blue. The three beams are then brought together and project the complete video image.

What does lens shift mean?

Lens shift means the lens shift. With the lens shift function on the projector, the video image can be shifted on the screen without moving the device in such a way that distortions are compensated for. A large lens shift increases flexibility when placing the projector.

What does HD mean?

HD, also HDV, is the abbreviation for high-definition video. It is a further development of the digital video standard. In addition to 3D, HD is currently the best technology in video technology.

What does HD ready mean?

HD Ready means: ready for HD. The label was created in 2005 by the European Information, Communications and Consumer Electronics Industry Technology Association (EICTA). The manufacturer-independent label HD Ready may only be used for devices that can display HDTV (high-definition television). Requirements for the logo include the ability to display full images (1280 × 720 pixels) and fields (1920 × 1080 pixels), a native resolution for the 16: 9 format with at least 720 lines and certain connections such as HDMI, YPbPr, DVI- D / -1.

How do I connect an HD projector to my laptop?

If both devices are equipped with an HDMI connection, you can use an HDMI cable. If not, you can put appropriate adapters in between. If the projector has a VGA connection, you need an adapter HDMI to VGA. You can also connect the laptop and projector via the USB ports.

How long does a projector lamp last?

Depending on the load and manufacturer, the lamp lasts between 2000 and 8000 hours. With an LED projector, it takes up to 20,000 hours. The more often and longer the projector runs, the shorter the lifespan. Some projectors have an eco mode that protects the lamp and reduces power consumption by adapting the brightness to the surrounding light.

How far from the screen should the projector stand / hang?

As a rule of thumb, the width of the screen should be half the distance between the viewer and the screen. Here you will find a projection screen calculator.

Which projector is the best? – Which projector is the right one?

There is no such thing as the best projector. There is only the right projector for you! The decisive factors here are the area of application, space and the budget. Read projector tests carefully. Here you will find all the important information about buying a projector.

Who repairs projectors?

If your projector is defective, you should not lend a hand yourself, but have the device repaired by a specialist or the manufacturer.

 

Alternatives to the HD projector

A possible alternative to the HD projector is your LCD television. In a small apartment, the size of the device can be a problem. If the television is not running, the very large black block in the room is annoying. In contrast, an HD projector is very small and inconspicuous.
Even a very large television does not offer the cinema experience like a projector. Another disadvantage is the image quality. LCD televisions only have a low black level.
When it comes to power consumption, driving a large screen is not necessarily cheaper than using a projector. The prices for a device with a competitive screen size are significantly higher than those of an HD projector.
For real home theatre enthusiasts, there is no question of an alternative. In addition to their video projector, they also have a television in the living room.
