The 76740I Cosmopolitan Electrol Wall & Ceiling Screen from Da-Lite is designed to be mounted or hung from a wall or ceiling. Its 105 x 140" viewing area has a 180" diagonal and 4:3 aspect ratio.
The Matte White viewing surface is seamless and offers a 120° total viewing angle (60° half angle) and a gain of 1.0. Matte White is a fiberglass surface for non high-definition projection and preserves color as well as black-and-white images. It is suitable for environments with controllable ambient light. Standard black backing retains projected brightness on the front of the surface. Matte White can be cleaned with mild soap and water, is flame-retardant and mildew-resistant. It is also GREENGUARD GOLD Certified.
To control your screen, a three-position Decora-style wall switch is included. A Video Projector Interface allows the screen to be raised or lowered automatically when your projector is turned on or off. Your projector must have a 12V or 5V lead to operate the interface.
