Reasons to choose the best UST projector

Easy to set up

A regular projector with a long throw requires a ceiling mount or tripod mounting, or you need to prepare a table to place the projector. Besides, you have to leave a proper distance from the screen. However, a UST projector can sit a few inches from the screen and won’t occupy too much space. Also, you won’t need to rustle with the wires.

Better image quality

UST projectors generally are equipped with laser light sources. Laser light source means higher brightness, more natural color production, and stable performance. Hence UST projectors can deliver massive, high-contrast, bright images even standing up well to ambient lighting.

Things need to know when buying the best UST projector

Requires an ALR screen

With a regular projector, a flat clean white wall may suffice, but UST projectors differ a lot when projecting with or without a projector screen. Because the UST projector produces high-value light on the screen at a very short distance, the light above the unit will impact the production of images. There is an ALR screen on the market that is designed for a UST projector. If you are interested, you may refer to Ambient Light Rejecting Screen – How Does It Work?

Choose better resolution 

It seems all the UST projectors claim to be 4K featured. But parts of manufacturers are setting their language traps here. Not all the 4K resolution is native 4K. To be more specific, parts of UST projectors manage to realize 4K resolution by making use of pixel-shifting technology. Not saying that pixel-shifting is bad, after all, pixel-shifting 4K performs better than 1080p image output. Just try to pick the UST projector with true native 4K if your budget allows it.  

Good Onboard audio is important 

We all know TVs typically offer subpar built-in speakers. When we choose a UST projector to replace the TV, we would want it to provide sound quality on par with the TV. Especially when we’ve got a massive screen from the UST projector, we would want good audio to match. Therefore, when choosing the UST projector, you better focus on these including great onboard speakers.

Downsides of the UST projector

Cost more

In General, Ultra Short Throw projectors cost more than regular projectors. It still requires a higher cost for laser projectors than the developed lamp technology.

Long input lag

Most UST projectors suffer from longer input lag than regular projectors, not to mention the gaming projector. Under the most condition, longer input lag won’t affect the movie viewing experience but is quite unfriendly for gamers. If you plan to play games on UST projectors very frequently and would mind the influence brought by long input lag, maybe a UST projector is not your best choice.
