SUMMARY
3840x2160@60 Hz refresh rate no longer available in kscreen-doctor or monitor
settings, only 30 Hz. Before recent updates 3840x2160@60 was available.
STEPS TO REPRODUCE
1. Attempt to pick 3840x2160@60
2. No possibility to pick 3840x2160@60
3. 3840x2160@30 only available
OBSERVED RESULT
Plasma defaults to lower resolution by auto-detection - 2560x1440@60.
This is unexpected behaviour. It worked good in older releases.
