Give yourself the gift of a true home theater system with this Motorized Projection Screen from Monoprice!This screen is made from a high-quality four-layer fabric. The surface layer is embossed with PVC microdots, which produces a 1.0 gain across a extra wide 160 degree viewing angle. The second layer is made of PVC, followed by a fiberglass layer, and another PVC layer to complete the screen. The result is a smooth screen surface with a stretch rate of less than 1%. By comparison, traditional chemical treated fabric screens have stretch rates as high as 33%!The screen can be mounted on the ceiling or on a wall. It is raised and lowered using a Somfy motor with an RF remote control. Somfy is the leading manufacturer of specialty motors, which provide ultra-smooth, silent operation and are known for their durability and long life. The screen measures 106 diagonal inches and is sized for a 16:9 aspect ratio.
