Lots of modern TVs have all sorts of backlight and contrast processing. If you go from a dark scene to the same scene with peak white in it, you can see the black levels change horribly on some displays.

xbmc limited unset, no xrandr hack -> test images display correctly in thumbnail and full screen
xbmc limited set, xrandr full RGB -> test images display correctly in thumbnail but blacks are crushed in full screen

xbmc range setting checked (=LIMITED)
Picture THUMBNAILS blacks okay
Picture FULLSCREEN blacks crushed
Video THUMBNAILS blacks okay
Video FULLSCREEN blacks okay
Side note:
When the black-level-test-image is put in a video, the blacks are not crushed! Only fullscreen picture seems affected.
So after all it really may be a problem regarding fullscreen-pictures being processed differently than fullscreen-videos? I don't have any other explanation.
I even put out my old media player to compare the same videos and pictures and on the old player picture and video give the same result.

Is black black? Do you see all rows in the last one? (It's okay, when you don't see the top most three squares), but if a full line is missing - something is wrong.
