The screen that is installed is MDW-250. This is a largest single unit optical projection screen in the world. Solstice™ series projection screens from Mocomtech are ultra-high Gain optical SD/HD/3D screens designed to perform well under any lighting conditions, including bright ambient lights. Innovative materials and manufacturing processes used for the Solstice projection screen deliver 18 times more brightness as compared to a standard matte white projection screen. The specially designed, precise, lens-like curvature helps eliminate hot spots, displaying only the light from the projector while diffusing ambient light.
