The projector is a device that allows you to view video on white surfaces through the light of a lamp. This technology has evolved over time and we must not think that these are the old devices that you might see in some vintage movies. Nowadays there are different types, those that are used in the cinema are much more technologically advanced while those for home use are more compact and have a lower quality.
If you are wondering why you should buy a projector when you have high resolution TV screens available, the reason is actually very simple, it is about wanting to recreate the cinema experience in your own home, dimming the lights and projecting on a cloth or directly on the walls of the house, your favorite movie, perhaps by connecting the device to a seven-channel audio system with subwoofer in order to enjoy a real cinema experience.
Rank #1: Resolution and quality
The problem with home projectors is the poor quality of the image. To obtain a high resolution, as you might have on a Full HD TV, for example, you need to invest at least a few hundred euros, opting for projectors that have a native resolution of at least 1,920 x 1,080 pixels.
Quite different speech if you want to get a 4K image. While with a latest generation television it is possible to have this technology at an affordable price, projectors capable of displaying images at 3,840 x .2160 pixels are still very expensive, in some cases exceeding a thousand euros.
The market is still moving in that direction, just as it has already happened for TVs, Canon, in particular, has unveiled a projector for large events and museums with native 4K and latest generation ISE 2020 lenses. Instead of a lamp, it uses a DLP laser capable of generating 40,000 Lumens, thus allowing it to project images even in lighted rooms without affecting visibility. Extraordinary 10-bit HDR technology that can reproduce over a billion shades of color and above all the 1,000-inch diagonal, for projections visible from a maximum distance of 176 meters.
Rank #2: Educational and work use
Projectors are often used for educational purposes. Their installation in museums, art galleries, universities, congress halls is almost a constant and you will surely have used these devices if you have found yourself in one of these contexts. As far as museums and art galleries are concerned, they are used to project explanatory videos in special rooms, while as regards the university environment and conference rooms they are connected to computers through which students can view information slides.
In these cases, large projectors are used, because they offer a higher lumen value and there is no need to significantly reduce the lighting in the room.
On the other hand, a different discourse can be made with regard to the workplace. Office workers will have at least once witnessed or given a presentation on a project. With a projector it is much easier to convey your idea, viewing videos, computer slides and documents of various kinds. In this case it is possible to have your own personal projector, of small dimensions, to be connected perhaps to the smartphone to immediately find all the necessary files.
Rank #3: Which projector to buy?
In light of all the possible uses, if you are still wondering what could be a suitable projector for your purposes, try to understand the use you will make of it. If you want to sit comfortably at home watching a movie, you will probably have to opt for a projector with a high quality output and that can be easily connected to an audio system (remember that these devices do not have built-in speakers unlike a TV) .
If you are a director of museums and art galleries, you may need to opt for a projector with a high lumen value and highly professional, while instead, if you are a manager or otherwise work in the office, a portable product to use for your presentations could be the most suitable choice.
Rank #4: Technical features
After figuring out which product to buy, it’s time to take a look at the technical features. Of course, the main factor to always look carefully is the resolution, the maximum supported one but above all the native one. These are two completely different voices, so don’t be fooled by those who try to sell you a projector by passing it off as native 1,080p when in reality it has a lower output.
To avoid these real scams, all you have to do is read the “native resolution” item and make sure that it is at least 1,280 x 720 pixels, that is, capable of returning an image in HD. The supported resolution, although it still needs to be checked, is usually less important since by now, most devices are able to support an input signal equal to Full HD.
The second element is the lumen value, this will establish the possibility of use in a more or less illuminated environment. The higher the lumen value, the more illuminated the room in which you project images and videos may be, however, at the same time, the price of the product will also rise. So if you don’t have a real need for projection in adverse light conditions, we recommend that you choose a projector ( Here is the list of the best products) with the lowest lumen value, so you will also safeguard your wallet.
Finally, the size of the projector. If you have to always carry it with you for work reasons, it is better to choose a portable device, perhaps you can connect it to your smartphone via USB cable. However, in this case, forget about being able to project films at a satisfactory quality.
