Uniformity-Digital Projectors

Brightness uniformity is the percentage of brightness carried throughout a projected image. When image is projected on screen, it is needed to see how brightness is spread on screen, particularly from centre to the corners of image. Brightness should be even all over the image. Some projectors have difficulty carrying brightness to the corners of the screen.Look for at least 85% or higher uniformity percentage for consistent image quality across the screen which will also ensure fewer hot spots or bright areas on the screen.
