What Is An Ultra Short Throw (UST) Projector Screen And Why Should You Want One?

If you are using a UST Projector without a UST Screen specially designed for UST projectors you will not enjoy the best image quality the projector has to offer (the same goes for using just a wall, which is usually even worse).

Projectors usually only provide a great picture in a darkened room but a specialised UST projector screen also enables great image quality in a lit room (and even better dark room performance too).  With a 100 inch-plus UST screen your friends will think you have a giant TV.


There are several reasons for the improvements a UST screen provides:


1.  Without a UST screen the majority of the light from the projector directly under the screen will be reflected up to the ceiling, not to your eye level.  This is just physics; the angle the light hits the screen or wall at is the angle it gets reflected at. Obviously this seriously diminishes the brightness of the light (the image) you  see at your seating position.


2.  Not only that, even in a darkened room all that light hitting your ceiling gets reflected into the room and lights it up, which washes out the contrast of the already diminished image you are seeing (unless you have a black or very dark coloured ceiling that is also zero sheen).


3.  Most walls are not perfectly flat, they have ripples that you wouldn’t see, until you shine a light up them at an extreme angle, just like a UST projector does.  Then you might see the shadows that give away where the ripples are.


A UST screen overcomes these problems and gives you the best image by incorporating a surface structure that is designed to reflect the light from below straight out into the room to your eyes, at the same time as rejecting light from above (i.e. room lights and ceiling reflections).


Of course it’s also perfectly flat to eliminate any distortions.


Combined with  Ambient Light Rejecting (ALR) characteristics (specifically CLR i.e. Ceiling Light Rejection) and a gray layer in the screen material you get greater contrast, richer colours, and a more vibrant, TV-like image even in a lit room!


Take a look at the videos below which summarise  all this pretty well and show how a UST ALR/CLR screen greatly enhances the image.


For use in both darkness and ambient light UST screens are ideal for UST projectors such as the Samsung 4K UST, Xiaomi Mijia UST 4K Laser, Optoma UST 4K UST, LG UST 4K, Vava UST 4K, HiSense UST models, plus ANY UST projector model.
