i've been looking on the net for this, found some stuff, but still, nothing really that pushes me to change it..
So, on my xbox360, the display settings, you can choose hdmi color space: rgb, source, auto, YCbCr709..
It was first on rgb, but i've heard that ycbrcr.. is actually way better. You have better colors, sharper quality.
Does anyone has an xbox, and set to this setting?
