Washed out external monitor on M1 Mac mini on usb c

Any info about fix in 11.4?

Don't expect a fix soon, this is still an issue even with the latest macOS 12 beta. Apple does not seem to have much inclination fixing this issue apparently. :(

I have an HDMI to USB-C cable - same issue. Hope Apple gets a fix for this.

On my 4K LG monitor, I went into the monitor settings > picture > game adjust > decrease the Black Stabilizer slider to 0. I now have deep blacks.

True. Apple would rather be a TV company. :-))

As mentioned, I have tried all the motheds (including disabling HDR) without any progress. Only thing works is to use thunderbolt cable.

For me only this script worked.

It changes not only /Library/Preferences/com.apple.windowserver.displays.plist file but also one more which has external display UUID in name.

See my post on this. I had to enable HDR to solve the issue.

Unchecking the HDS tick box worked for me!!. Thank you!

Unchecking the HDR worked for me!! Thank you!!
