Hi.
Fresh arch install with KDE 6.2.
Problem:
HDR in the desktop envioment works as it should only on main monitor. secondary displays have HDR Enabled and gets a HDR signal but colors are off by a long shot.
What i have altered with my system:
I have installed the entire KDE group from Arch User Repo.
To get HDR toggle to work / show up I modified my /etc/enviroment file by adding
KWIN_DRM_ALLOW_NVIDIA_COLORSPACE=1
and restarting SDDM
Screenshots of the desktop show that the "image" is the same on all 3 displays
Isn't that just your monitors not being the same?:
No they are the exact same model and in Windows they line up "close enough"
Why this is an issue?:
Id like to have HDR enabled on my nice monitors. Thats mainly it really its a nice feature and i enjoy the color space it gives me even tho most applications are not HDR ready. ( plus tripple display gaming)
So yeah anyone got some good tips on how to debug this?
