SUMMARY
***
Hi,
I am using KDE 5.24.5(x11) with sddm, but "RGB range" is missing in screen settings which seems support by KDE a years ago.

The intel drvier misconfig RGB range and needs to set manually, and "xrandr --set "Broadcast RGB"" workaround confirms works.

Thanks
*** 


STEPS TO REPRODUCE
1. Open screen setting
2. No "RGB range" option
3. xrandr quirk to set "RGB range" works.

OBSERVED RESULT
"RGB range" option missing


EXPECTED RESULT
"RGB range" option exist

Does it work on Wayland? I believe this is a Wayland-only feature.

Hi,
Oh, i didn't notice this is a wayland only feature. Tested on wayland session, and perform as excpeted. 
Is that possible to support this feature on X11 session too? It's really helpful when grphic card drvier choose wrong rgb range.
Thanks

I don't think so, sorry. It's one of those things that really only works well on Wayland. Give the Wayland session a try, you may find that it works well and there are other goodies too!
