We're looking at the possiblity of getting a DLP projector for work. It would be hooked up to a PC and used for PowerPoint presentations and other dull stuff like that. Previously we've always had LCD projectors, but the price difference between LCD and DLP can be fairly large, and price is all important to us. I'm aware of the possibility of rainbows, but I'm curious as to whether they affect static images in the same way as they appear on film. Is there anyone that can give it a test for me please?
