It is > expected that games will be rather dark with that. My goal is that the monitor is running at 100 nits. It has a max fullscreen luminance of 250 nits. So u have to set Max SDR Brightness to 250 and the the Brightness at 40 to achieve that goal ? In addition, what is the brightness slider doing when the monitor is running in sdr mode ? Cause changing the brightness slider there does also not adjust it on the monitor settings. How is that interacting ?

No, this does not help that time. It worked last time to fix a hdr issue in 6.2 before you applied a fix, see here: https://bugs.kde.org/show_bug.cgi?id=494502 -- You are receiving this mail because: You are watching all bug changes.
