Size and adaptability aren't the only reasons to go big either. Larger screens have additional benefits, such as lower eye strain. In this sense, a projector is arguably the healthiest option, provided you are at an appropriate distance from the screen to start with. Another domino effect of a larger screen is the resolution.
If all things are the same, then a 4K projector has the screen space to better display 4K resolution. When it comes to projectors, size matters, and that directly impacts many of the other benefits of a large screen. Projectors are capable of generating much larger images that reduce visual fatigue. The reflected light is less intense to the eyes than the light emitted, allowing you to focus on the task without additional effort.
Of course, there are some situations where a UST projector would work better. Maybe your ceiling is too high, the depth of the room is too short, or you live in a rental house where drilling into walls and ceiling is prohibited. In those cases, or if most of what you see is during the day, you should buy a 4K TV. All large screen televisions are brighter than any projector, look better with the lights on and, in most cases, create a better overall picture than a similarly priced projector.
In the past, buying a 4K projector was a luxury considering that it wasn't the most convenient or economical option. By using special lenses and mirrors, an ultra-short distance projector can create a very large image on a screen or wall from a very short distance, so it fits in rooms where a traditional projector cannot. And the reason 4K projectors can't compete with 4K televisions equipped with OLED technology is the fact that black OLED projectors are difficult to reproduce. While almost all 4K TVs now broadcast 4K, this isn't always the case with a 4K projector.
The thing is that very few people have a home theater system and, for the few that do, they don't have a 4K projector. The difference between a projector and a television is that projectors create an image by shining a light through a lens onto a screen, while televisions use pixels to create an image directly. The high cost, the rather complex configuration and the additional equipment needed for an impeccable home entertainment thrill make the comparison between the projector and the 4K TV unreasonable. Thus, for example, a projector with 2000 lumens will be twice as bright as a projector with 1000 lumens.
Instead, you'll have to connect your 4k projector to other devices to set up your own smart platform. Most UST projectors have two or more adjustable feet to help you align the chassis with the wall, but they have far fewer manual lens adjustments (such as lens shift and zoom) than many traditional projectors with similar prices. If you imagine a traditional projector in the back of a room and a UST projector in the front next to the screen, a short-range projector would be halfway between them.
