Option to auto-switch to fixed mode when VRR mode activated for a real display

[waydabber]

Monterey detects Variable Refresh Rate displays and depending on configuration tends to auto-select VRR. Even when the user select a non-VRR mode, sometimes after sleep or becuase of some unrelated display reconfiguration the system restores VRR.

This is a problem for cheaper displays with less convinfing Freesync implementations with no ability turn it off on the display OSD.

A feature could be added to auto-switch to the corresponding Fixed mode from VRR mode whenever VRR mode is engaged.

The opcion could be added as a tool under real displays.

See this: MonitorControl/MonitorControl#981

I think if you implemented this feature you would make quite a lot of people very, very, very happy (myself included).

I'm a very strong 👍 on this if that helps you prioritize!
