Da-Lite Parallax projection screen 195.6 cm (77") 16:9

Parallax is an ambient light-rejecting technology that features a micro-layered optical lens system that rejects light. With extremely wide viewing angles. no speckle and no glare. the surface is ideal for applications in Pro AV. Additionally. the surface is flexible. ships in a roll and is easy to install.Each layer of Parallax plays a role in preserving the image that is reflected back to the viewer in high ambient light environments. Some layers absorb light while one special layer is shaped like a microscopic saw-tooth that blocks light from above resulting in the preservation of high-contrast.bright images in brightly lit environments.The projector needs to be positioned within the vertical viewing angle to ensure the light is not rejected.
