Projector instead of TV: what you need to know about projectors

Translation: machine translated
With projectors, you get more picture for less money than with TVs. If you want to reach 100 inches or more, you will have to spend a low five-figure sum on a TV set. By contrast, you can get a high-end projector for this screen diagonal for a mid four-figure sum.
It's not uncommon for a projector to have its own speakers, but it's still worth planning to buy a sound system, especially for home cinema. To get a good projector image even in light-flooded living rooms, you also need a screen, but for now we'll focus on the projector.
DLP or LCD
Conventional LCD projectors have three LCD panels. They generate the image that is later projected onto the screen. Each LCD panel generates the image for one of the three primary colours: red, green and blue.
Luca Fontana has explained the functions, advantages and disadvantages of the two technologies in detail:
In the end, he doesn't want to decide whether DLP or LCD is better. But he does have a rule of thumb, which is not a law carved in stone.
Would you like more insights into the inner workings of a projector and an explanation of how it works?
Resolution and brightness
Currently, most models have a full HD or even lower resolution. 4K or UHD models are now not uncommon. In terms of screen diagonal, projectors from around 85-inch screen diagonals upwards are only more expensive than UHD TVs at first glance: in relation to how large the displayed projector image is and how expensive a UHD TV with 85 inches or more would be, even high-priced projectors could almost be described as "bargains".
The brightness with which a projector shines also has an effect on the price. This is measured in lumens. In your light-flooded living room, you naturally need a higher brightness than in the furnished basement or if you also want to draw the curtains during the day. The difference between 500 and 5000 lumens is immediately noticeable.
Projectors for different purposes
It's worth choosing your new projector according to its main use. As described above, for example, DLP models are the better choice for home cinema and LCD projectors are better if you tend to view texts and tables on the wall - in the office, for example.

But even if you don't have UHD source material, a UHD projector will upscale lower-resolution images to UHD resolution. With the usual screen diagonals of 85 inches upwards for projectors, the image is only razor-sharp if you choose a model with UHD resolution.
Projector for gaming
Gaming is not just about good colour reproduction. Short response times and a high refresh rate are at least as important.
Kurzdistanz-Beamer
(Ultra) short-throw projectors with their special lenses are designed to be placed directly in front of the wall they are projecting onto. Their minimum distance is minimal and you can use them in rooms that are too small for other projectors or are unsuitable for other reasons. And nobody can stand in front of the image either.
Portable projectors to go
In order for a projector to be suitable for you to take with you, it is usually smaller and lighter than stationary models. Some portable models even have a rechargeable battery. However, you will have to make do with lower resolutions and less bright lamps than with larger projectors; they are not suitable for stationary use.
Projectors for office, school and university
This is about projectors whose strength is a sharp, high-contrast image with clear contours. After all, it's more about being able to read texts well and recognise the contents of tables - and not about how impressive an explosion looks in the latest Michael Bay film.

Since then I've had the opportunity to test out all the newest technology for you. I've done reviews at Curved, Computer Bild and Netzwelt, and have now arrived at Galaxus.de.
