Tensioned Cosmopolitan with High Contrast Cinema Vision fabric and 110 volt motor. Electric Screen that Mounts on Wall or Ceiling. Screen is tensioned for an extra flat surface for optimum image quality.

Ideal for applications where a recessed installation is not desired or feasible. Patented in-the-roller motor mounting system for quiet operation. High Contrast Cinema Vision is designed for today's moderate output DLP and LCD home theater projectors. With its specially designed gray base surface and a reflective top surface, this screen material is able to provide very good black levels without sacrificing the white level output. Where ambient lighting is moderately controlled, High Contrast Cinema Vision offers deep life-like colors and greater detail and sharpness to the image. Gain 1.1 with a 45-degree viewing half angle.
