From Manufacturer
The 28804V Parallax 49 x 87" Fixed Frame Projection Screen from Da-Lite features a special fabric that mimics the screen of a television. This darker surface is designed for maximum glare rejection, allowing the projector to be used in environments with elevated levels of ambient light. Its multi-layered design helps reject light coming from above so that only the image from the projector gets reflected.
Parallax UST 0.45 Ultra-Short Throw Screen Surface
Parallax is an ambient-light-rejecting technology featuring a micro-layered optical lens system that rejects light. This technology mimics the look of a television when it is on and when it is off, but without the glare from windows or lighting fixtures. Parallax UST 0.45 is unique because it is designed to be used with a short-throw projector (less than 1.5:1 throw ratio) that is mounted below the screen. It features a horizontal viewing angle of 160°, a vertical viewing angle of 110°, and a gain of 0.45
