VistaBead 100 rear projection screen represents one of most advanced concepts in rear screen technology. It is comprised of two elements specifically formulated for extremely high contrast images with incredible brightness uniformity. Screen employs unique one way light valve design that maximizes resistance to ambient light sources. It offers particularly powerful combination of high vertical and horizontal light distribution, unsurpassed image contrast and ultra-fine resolution. Combination of advanced optical light control and perfectly black tinting prevents ambient light sources from degrading image black levels. Result is crisp images with rich color and contrast, even in high ambient light environments.
