Da-Lite’s chemical formula for their HD Progressive line of projection surfaces is designed to perfectly reflect and preserve the image being projected. When you look closely at a projection screen surface, many surfaces look like varying grains of sandpaper and others have microscopic variations on the surface. This causes pixel loss and “noise” in the image because the surface isn’t able to perfectly reflect the projected image. As projection resolution advances, pixel preservation becomes much more important to preserve the clarity of your image. The chemistry behind Da-Lite HD Progressive surface is formulated to create a surface free of microscopic variances allowing the screen to essentially disappear. The result is brilliant light, vibrant color and the best surface for HD, 4K and Ultra HD projection.
