I recently set up my new Mac Studio with my Samsung CRG9 external monitor, that supports up to a 5120 X 1440 resolution at 120Hz. I set my Mac Studio to run at that resolution and refresh rate, but for some reason whenever I wake my Mac from sleep, the refresh rate will switch to the "Variable (48Hz-120Hz)" setting. I don't want the variable refresh rate on this display, I would like it to just stick to the full 120Hz refresh rate at that resolution at all times because it makes moving things around the display a bit jittery when using the variable one. Not sure why it's switching back to variable after waking it from sleep but is there a way to prevent this?
Like I said, using a new Mac Studio running macOS 12.3.1, and a Samsung CRG9 external display.
