SeVision 3D GX is the world's premier passive 3D coating. It is recognized and preferred by 3D licensing companies world-wide, and one of the few home theater screen surfaces that is RealD approved. With a signal-to-noise ratio up to 250:1 at a 2.4 gain, ghosting rarely occurs. Because of the amazing uniformity of gain and texture, the SeVision 3D GX may also be used for 2D projection. The SeVision 3D GX coating is water-based, which prolongs the life of the screen material and gain. A proprietary and unique seam welding process ensures our screens have no visible seams under projection conditions. Advanced 100% water based coating technology and application processes ensure a smooth finish and consistent brightness across the entire screen surface with no degradation of gain or extinction ratio over time.
