My company has just bought a BENQ PB2220 DLP projector for demos/presentations but the colour reproduction on it is very poor - nothing at all like the colours on the PC driving it - very washed out with blues looking grey etc - almost as if it is showing a limited palette. Is this "normal" - i.e. a limitation of this "cheap" projector or are we doing something wrong or does it need to be displayed on a proper projector screen to get good colour (just projecting onto a wall at the moment, but I have tried projecting onto bright white surfaces without much difference). We are running it at it's native XGA res of 1024x768 via VGA cable. No colour options within the menu for VGA, only brightness/contrast which do not help.
