I was off over Christmas and was playing around. I have a Theater Room with dark colors. I have a 159" Dalite High power Scope screen. I have a Sony VPL 40 with a lens. The image is bright and beautiful. If I put a piece of printer paper on the screen it looks like a very dull area. I also have an LG 181d in a den with a 120" painted screen that we use as a tv. I can see both screens at the same time and there is no doubt the High Power is brighter. When I place printer paper against the painted screen it dissapears. After watching the painted screen for a few minutes though it looks great. If I could not directly compare the two screens I would think they were even. While I was off I turned the den projector to the wall beside the screen which is sage and after a short time the image looked good. I eventually carried the projector up to the living room and projected on the walls in there. The wall is a mustard color. What was amazing is that on the mustard walls a white object looks white, even though I know it is impossible. I know if you measured the mustard color it would measure terrible but once your eyes adjust there was no mustard color to the white on the screen. I am beginning to believe all of the miniscule adjustments to paint blends are a big waste. If white looks white on a mustard wall after your eyes adjust there is no way your can notice slight changes in paint mix.The printer paper against the mustard was a bright spot though.
