I did what I think I needed to do to set the RGB range to full, but from looking at xrandr can't tell if anything happened... ideas?

You can use

Code:

xrandr --query --verbose

to make sure the settings are ok.

Then just set xbmc to 16-235 and use avshd709 (or other patterns of your choice) to verify.

I recommend also checking the resolution patterns. Sometimes xbmc scales the picture unnecessarily.

Hi Imyllari!

Thanks for responding. This is actually turning into a deeper rabbit hole than I had hoped.

I discovered that with the RGB set to "full" even with 16-235 output selected in XBMC the picture was too dark. My TV is a 65VT30 using an ISF calibration preset on one of the HDMI inputs and the color range is set to "auto"... changing it manually to 16-235 doesn't seem to change things so I'm guessing that auto is selecting 16-235 for this content.

As a benchmark/comparison I am playing same source file from original BD on a PS4, using a different input (with same video settings) through my Denon X4000.

The closest I can get is when I don't override RGB output to full (so I'm guessing it is limited) and I set 16-235 on in the menus. It is close, but still slightly different than the original BD.

Interestingly with this "close" setting, the XBMC menus look terrible, very very gray, but content seems as close to original as I can get.

All in all very confusing and a little disappointing.

Here's the output (after reboot so didn't mess with RGB) of xrandr;
