1) Full range output:

Code:

xrandr --output HDMI1 --set "Broadcast RGB" "Full"

, disable VA-API decoding

Tried that, crushed blacks for me, if i take my BR Player for Ref. that streams the same MKV, i
see many details lost, if u see A - B u recognize even more..

BUT VA-API diable doesn't make any difference for me, not in the HUD and neither during movies...i see no difference in color space..?

2) Limited range output (with nightly):

Code:

xrandr --output HDMI1 --set "Broadcast RGB" "Full"

, disable VA-API decoding, set 16-235 range in system -> video and set limited range RGB from your TV/monitor. This gives the best quality (no banding in greyscale ramp, blacks and whites don't clip).

U say..set 16-235 range in system...i can not find that option in my system - settings - video....same menu where the VA-API Disable option is..? I can't fin it..?

My full testing results for those who might be interested:
ubuntu, mplayer2 vo gl
xrandr output range full
1 black clipping: 20 lowest visible
3 white clipping: 234 highest visible
misc a greyscale: banding visible (darker looking stripes)
misc a color clipping: red 233, green 233, blue 233 visible

ubuntu, mplayer2 vo gl
xrandr output range limited
1 black clipping: 20 lowest visible
3 white clipping: 252 highest visible
misc a greyscale: no banding visible
misc a color clipping: red 235, green 235, blue 237 visible

oe 3.2.3 xbmc 12.2 git:97a9f05
xrandr output range full
1 black clipping: 20 lowest visible
3 white clipping: 234 highest visible
misc a greyscale: banding visible
misc a color clipping: red 251, green below 219, blue 243 visible


This is what i am basically using just with VA-API disabled (doesn't do any change for me) and i still see ur results...colors are way off..

edit: I just noticed that this issue has been seen earlier at http://openelec.tv/forum/116-vaapi-intel...saturation

Best for me works if i set xandr to limited 16-235 and then tune the display to it, i still see some lost detail but for now it works best for me
This can't be a real...just can't believe it....that is something i have never thought i´d have to deal with
