Today i tried to find the HDMI Black Level Setting in my TX-P50GT30 (European) and i did not find it too... good to know that it does not exist. In my oppinion the European Model is fixed to Limited Colorspace.

At least not on my TV - you can youse xrandr to check what's available for yours. On mine it reports:

Code:

Broadcast RGB: Full
    supported: Automatic, Full, Limited 16:235

So you can clearly see that both are accepted (at least at input level). Right now HDMI negotiation of Full is forced by autostart (see post #1). But Kodi itself sends Full or Limited - it depends on settings. At least on my TV i can clearly see difference - with Limited colors are washed out. But with Full movies are very dark. Yo can check which settings are best on post nr 1360.

But (IMHO only) best settings are with Kodi set to Full, no dithering, but on TV level setting forced to Limited (usung xrandr). So on my setup autostart looks like this:

Code:

OUTPUT=`xrandr -display :0 -q | sed '/ connected/!d;s/ .*//;q'`
xrandr -display :0 --output $OUTPUT --set "Broadcast RGB" "Limited 16:235"
/usr/bin/kodi --standalone

Just to add to the confusion, my 2010 UK Panasonic plasma also has no settings for HDMI = it expects limited. It also doesn't advertise the right hdmi info frames for range, but both Intel and AMD drivers will still offer the settings as shown in your xrandr output.

What limited is though. is not strictly 16-235 anyway, the HDMI specs allow for over and under, so when the driver is set to limited and squashes to 16 - 235 then it's really doing more than needed. IIRC the HDMI specs say no to 0 and 255, but my TV at least doesn't seem to care. There are also CEA specs to consider, I don't know if they overrule HDMI, but IIRC they still allow for over 235.
