[Mark the Red]

1. I was experiencing a degree of black crush using the 'full rgb' xrandr command. (I failed to perceive this without patterns, with them it was quite clear)
2. I was not getting a properly calibrated image leaving everything as is (default).
3. I do get a perfectly calibrated image by using xrandr full rgd + limited output option from within xbmc.

If I check the limited range option after the xrandr command it defaults to the original washed out greyed image.

My TV is a Samsung PN59D8000. I have the color space calibrated via 10p white balance which may explain why my TV is somewhat abnormal in this matter. However, Samsung TV's are no small percent of the market share either...
