SUMMARY
The configuration of the Display & Monitor System Setting page don't persist after shutdown or logout.
This only apply to the RC1 and master branch, but not on the 5.27 release (but i'm not sure that is not a problem with some other newer dependencies).

STEPS TO REPRODUCE
1. Change some setting in Display & Monitor System Setting page (ex. scale factor)
2. Apply settings
3. Reboot

OBSERVED RESULT
The setting are reset to the default value.

EXPECTED RESULT
The setting persist a reboot.

EDID parsins was just improved today with https://invent.kde.org/plasma/kwin/-/commit/d563bc6c86d398a59409f5ea1ad556d93fb45f78, in fact; can you update to the latest version in a few days so that you get that commit, and try again?
