Bug ID: 506496
Summary: RGB Full value is not applied
Classification: Plasma
Product: KScreen
Version First 6.4.2
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Setting "RGB Range" to "Full" still keeps monitor at YCbCr 4:4:4 which looks
*bad*. Both Windows and macOS are able to use RGB Full 8-bit on this monitor. I
am unsure what logs I should attach here, so please let me know. Just in case I
thought it could be a link speed issue, I tried at 60Hz, and it does YCbCr
4:4:4 10-bit color instead for... some reason. I don't find any way to force it
on the command line, nor can I use wayland-xrandr to set it (which does work on
Window Managers)
STEPS TO REPRODUCE
1. Set "RGB Range" to Full
2. Nothing changes, screen doesn't even flash.
OBSERVED RESULT
[See attachment]
EXPECTED RESULT
Screen uses RGB Full range.
