Blake from SI Screens trains the Projector People team on Black Diamond screen material. Note the demonstration of the Black Diamond screen material versus standard white material at approximately (2:05) of the video. Unfortunately our room is not as dark as it could be because we have a light coming in from under the door. Then note the impressive image with the lights on at (2:50). This image looks a bit better in person, but you still get a sense of how well the Black Diamond screens maintain brightness and contrast with the lights on. The image is comparable to a plasma or LCD TV. Blake compares the Black Diamond image to an $80,000 image just a few years ago.
