When applying refresh rate chagnes in DF, the setting was reverting.

One monitor was stuck at 30, I set it for 60, but apply settings went back to 30.
The other was 60 -> 120 reverted back to 60.

Issue persisted with upgrade to v10.

Solution / Workaround was to set the refresh in w10 advanced monitor config.

Now DF reflects the windows setting.

Switching profiles in DF maintains the refresh rate.

Winblows Version 10.0.19045 Build 19045
Nvidia Geforce GTX 1630

When I switch back to 30, it goes, but wont go to 60 again by manual adjustment.

Also when either monitor is adjusted, both are reverted to the lower refresh rates.

I did save the profile with preferred refresh, and it does recall them when loaded.

Further..

When I set 120->119, it goes to 120.

When I set 120->100, it goes to 60. Setting 120 goes to 60

When I set 120->50, it stays at 50. Setting 120 goes to 60
When I set 120->30, it stays at 30. Setting 120 goes to 60

When I set 30->50, works
When I set 50->30, works

When I set 30->120, Setting 120 goes to 60
When I set 50->120, Setting 120 goes to 60

Bizarre.
