The 20582 Cinema Contour Fixed Frame Screen by Da-Lite has a 49 x 115" viewing area, 2.35:1 aspect ratio, and 125" diagonal.
The Silver Lite 2.5 viewing surface offers a 50° total viewing angle (25° half angle) and a gain of 2.5. It is a fiberglass multi-purpose front projection surface for non high-definition projection that is optimized for passive linear and circular 3D applications, and is also compatible with 2D projection. The silver surface maintains 99.3% of polarized light. Silver Lite 2.5 eliminates ghosting or crosstalk common with stereoscopic 3D projection. When paired with 2D projection, the gain and high contrast create an ideal surface for high ambient light environments or a low-output projector. Silver Lite 2.5 can be cleaned with mild soap and water, and is flame-retardant and mildew-resistant. It is also GREENGUARD GOLD Certified. Black backing on the back of the viewing surface prevents light bleed-through.
The aluminum frame is 3” wide by 1.63” and is covered with black Pro-Trim fabric, which absorbs excess light around the viewing area. The frame is slip-jointed at corners and joints. The screen also includes standard wall-mounting brackets.
