The 74660I Cosmopolitan Electrol Wall & Ceiling Screen from Da-Lite is designed to be mounted or hung from a wall or ceiling. Its 50 x 67" viewing area has an 84" diagonal and 4:3 aspect ratio.
The Video Spectra 1.5 viewing surface offers a 70° total viewing angle (35° half angle) and a gain of 1.5. It is a fiberglass surface with a reflective coating for lower output non high-definition projectors. It offers increased brightness with a reduced viewing angle and is suitable for uncontrolled ambient light. Video Spectra 1.5 can be cleaned with mild soap and water, and 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.
