Comment Re:DLP Rainbow effect (Score 1) 251
I would have to say that it is your brain filtering out uneeded information. It is the same way optical illusions work. I have a DLP projector. When I first got it I noticed the rainbow effect everytime I rapidly moved my eyes. Now after almost a year I never notice it even when doing that. Your brain learns to compensate, or at least filter out (ignore) the effect. I can only see teh rainbow effect when I put a whtie object in front of the light path and flick it back and forth rapidly.
In the way of refresh rates, it may be that some peoples brains are able to filter out the effect more than others. However, it does not mean that the brain still does not percieve the flickering, it jsut filters that out for your consciousness. Even though you don't notice the flicker, you can still get headaches and fatigue. The worst part is, most people don't pinpoint WHY they are getting these symptons and thus the problem is not cured.
