I went by Sound Advice to listen to some Polk Audio and got to check out some Mits. DLP's. I was not as impressed as I thought I would be, esp. for the price tag. What is the rainbow effect exactly? Is it only color related or what...I picked up on a lot of movement pixelation and some wierd kinda blurry looking areas at times. This was on an HD signal also. I don't know what to think. When I got home and looked at my 60" Sony LCD, I became even more confused. Both have their Pro's and Con's.
