I noticed rainbow effect but it's not distracting for me. When you get involved with the movie you won't find any. It may appear occasionally when you blink. Just now I finished watching Planet of the apes 3D, I was very much involved with the movie and the 3D, so I didn't notice any rainbow effects.Can anyone please confirm about the rainbow effect on this projector? How severe is it? I'm guessing there will be quite a bit of rainbow artifacts owing to the fact that it is a single chip DLP with a 2x speed colour wheel.
