John, how did you like this projector? I just couldn't get over the black level. They had just got it and it wasn't even set up completely but it is the nearest thing I've seen to a CRT projector. Don't get me wrong on the rainbows, I was going pass the door to the theater just when a scene in the film shows a dark room with a small light showing through the door. So I saw it in the corner of the eye only and I was moving. This is not a normal viewing situation. The Sharp site says that the color wheel has different speeds. I only know it's the best projector for that price I have seen.
