Describe the bug

Been a user for about a year

My setup is an M1 MBA with TB4 Dock and INNOCN LED external monitor connected on the HDMI of the dock.

For a year I have been having issues where half the time my external would not wake up after deep sleep. I needed to turn off/on the dock in order to wake it back up.

For the last few weeks I was having a new issue appearing: while in use the external monitor would go GREEN. Completely green... at first it was once in a while then every hour.

I replaced all cables but no fix. Then I removed Monitor Control and now everything works fine..

The only thing I could not replace is my dock because I do not have a USB to HDMI adaptor.

I am 100% sure that Monitor control was the root cause.

For the moment I am not using it anymore. Not sure if I can / how help debug. Let me know if you want to investigate. happy to reinstall it if needed.

Steps to reproduce

Use Monitor control with a setup similar to mine ?

Expected behavior

no GREEN screen; perfect wake up from deep sleep.

Anything else?
