My eyes have been tested to have a refresh rate 10 times higher than average. Consequently, I can't watch most DLP TVs or projectors without seeing rainbows everywhere when I move my eyes across the screen. I just received my GH2 and I know that the EVF is supposed to be much better quality than the LCD. Unfortunately for me, it looks just like a DLP does, with RGB rainbows streaking across all higher contrast areas of the screen.
