Original GitHub issue: https://github.com/MonitorControl/MonitorControl/issues/1032

Before opening the issue, have you...?

Searched for existing issues
Looked through the wiki
Updated MonitorControl to the latest version (if applicable)

Describe the bug

When the app is running, the refresh rate is kept at 144Hz even after you configure the monitor and the OS to enable Variable Refresh Rate (40Hz-144Hz).

Steps to reproduce

Make sure that you have configured your monitor to enable an Adaptive Sync functionality.
Launch MonitorControl.
Go to the "Display" panel in the System Preferences.
Change the refresh rate setting to use Variable Refresh Rate.
Set the monitor to show the refresh rate using its OSD.
The refresh rate indicator reads 144Hz all the time, whatever application you use.

Expected behavior

When MonitorControl is running, the Variable Refresh Rate setting in the OS is effective.

Anything else?

No response

Environment Information (please complete the following information)

- macOS version: 12.3.1
- Mac model: Mac Studio (M1 Max 24 core GPU)
- MonitorControl version: 4.0.2 Build 6965

One thing I forgot to mention: I connect my Mac and the monitor with a USB-C to 8K DisplayPort cable from Cable Matters.

Hi @Hanage999
Apparently there are known bugs with VRR and Monterey. Please see this discussion https://github.com/MonitorControl/MonitorControl/discussions/981

Hi @the0neyouseek , thanks for the reply and guiding me to a relevant discussion.

In my case the opposite happens: I enable VRR in System Preferences, but the OS reverts the setting after sleeps, restarts or reconnections to its monitor.

Hopefully Apple will fix the crappy VRR support in one of the future Monterey updates.

Same issue with my Dell G3223D. It doesn't store the VRR refresh rate after reboot. I'm on Monterey 12.5.1 (21G83). Seems to be still buggy there right?

This does not seem to be a MonitorControl issue specifically. VRR might be affected if there is activity on-screen, MC does not create such activity unless there is an ongoing software brightness adjustment. For other issues like VRR setting not remembered etc. the problem seems to be entirely at macOS level.
