My Macbook pro with M1 Max changes resolution on connected Monitors each time after waking up from sleep. External monitors are connected via USB C cables
Any solution?

Hello M1Mac_user,
Thanks for posting this in the Apple Support Community. We understand that you’re having issues with the resolution of your external displays after your Mac wakes from sleep. We can help!
A good place to start is to check for any macOS updates: Update macOS on Mac
Check to see if this is something that's isolated to just your user on your Mac, or if it's system-wide. Please use the steps from the section “Add a user” to create a new user on your Mac: Set up users, guests, and groups on Mac
Also, try starting up in safe mode and then restart the MacBook Pro: How to use safe mode on your Mac
"Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.
Safe mode is particularly useful when you're trying to resolve an issue that doesn't seem to be associated with using any particular app. As always, keeping your software up to date is the first step toward resolving any software issue."
Have a great rest of your day!
