Of all the calibration DVD's out there, GetGrey is the best I've used. I was able to get better accuracy than (DVE) Digital Video Essentials or the (out of date) AVIA DVD. I have adjusted my main monitor a KDL46XBR2, for color temperature, white balance and etc. and it has resulted in very natural and realistic colors. It's like looking outside through a clean window. It's jaw dropping to people who have seen it.
