The Da - Lite 28806V Parallax projector screen measures 54 x 96 inches or 110 inches diagonally, offering an HDTV 16:9 aspect ratio. It features Parallax Pure, an amazing ambient light - rejecting technology with a micro - layered optical lens system. This technology not only mimics the look of a TV both on and off but also gets rid of glare from windows or lighting. With wide viewing angles, no speckle, and no glare, it's perfect for Pro AV and home theater use. The screen surface is flexible, comes in a roll, and is a breeze to install. Different layers in Parallax Pure work together to preserve high - contrast, bright images in well - lit areas. Some layers absorb light, and a special saw - tooth - shaped layer blocks light from above. There are two surface options: Parallax Pure 0.8 for standard throw projectors (1.5:1 or greater) and Parallax Pure UST 0.45 for ultra short - throw projectors (0.4:1 throw or less). It ships unassembled and has a standard frame with a Pro - Trim finish to absorb light around the viewing area.

Using this Da - Lite projector screen is easy. First, unpack it carefully as it comes unassembled. Then, find a suitable place on the wall for installation. Make sure the area is flat and clean. If you're using an ultra - short - throw projector, choose the Parallax Pure UST 0.45 surface. For standard throw projectors, go for the Parallax Pure 0.8 surface. Hang the screen according to the instructions provided. When it comes to maintenance, use a soft, dry cloth to gently wipe the screen surface. Avoid using harsh chemicals as they might damage the micro - layers. Also, keep the screen away from direct sunlight and excessive moisture. In case of any big bumps or scratches, it's best to contact customer service for help. Enjoy your high - quality viewing experience with this projector screen!
