what is this rainbow effect?
is this where you are watching it and if you move your head you see a flash of RGB in your peripheral vision? I've noticed it on some newer model DLP's

I think there is definately better picture quality from the DLP's than from the LCD's from what i have seen, all the LCDs look washed out camparatively, i just think the LCD's aren't capable of the same contrast levels that the DLP's are, i've been looking into this for a good few months now.
