Hello,
I have a rather old Philips TV connected to my HTPC. The problem is: every once in a while the display goes completly cyan/magenta. I had the problem before with older HTPC hardware and the fix was to force the output of the graphics adaptor to Full RGB / RGB 4:4:4. Unfortunately, I did not find where I can make this setting in LibreELEC 9 (Milhouse build).
So far I tried
- setting "ColorSpace" and "ColorRange" in xorg.conf
- xrandr (but there seems to be no property for the pixel format, at least for the AMD CPU)
- Kodi settings (use limited color range)
Is there a way to force the pixel format to RGB 4:4:4?
