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

If I start to adjust things on a monitor the screen goes grey/scattered (not sure how to explain) as if it is ½ unplugged or something. I have to reboot to get things to work again.

Steps to reproduce

Connect via HDMI
Make adjustments in MonitorControl

Expected behavior

adjustments should happen and monitor should work

Anything else?

No response

As stated in the compatibility section, HDMI connections for the 2018 Intel, M1 and entry level M2 minis are not supported. You can use BetterDisplay instead as it supports all connections.
