Describe the issue

It cannot control the monitor hardware settings on my M2 Pro Mac mini.
Specifically, the volume slider and the contrast slider do not show up in the menu bar. Adjusting the brightness only adjusts the software brightness. When the sound output is set to the external display, adjusting the volume does not modify the volume although the macOS OSD changes.

LG's official app, OnScreen Control does NOT work.
The other app, BetterDisplay, works well.

All three apps work on an Intel Macbook Pro with the same monitor.

Expected behavior

Adjusting the volume and brightness should change the hardware settings as shown in the monitor's OSD.

Anything else?
