Glad I could help. Hopefully it lasts for all of us. I have not updated to 11.2.1 yet so hoping that doesn't revert it back but if it does, I guess I could do the process again.
The real question is how many hours did you spend with Apple Support?

It wasn't too painful. Almost two hours total. It was via chat so I could send them pictures of my screen as it was difficult to explain. I was able to message him this very post to prove it's not just me and my specific monitor as multiple incidents would justify involvement of Apple engineering. He appreciated that and got a new bulletin from engineering to do this plist process and if it didn't work, to reset monitor settings in the monitor OSD. The 1st suggestion worked so no need to reset in the monitor OSD. Apple engineering called back this morning to see if it worked and I told them it did, so there was no need to send them my system log files for further investigation either.

Newbie here. I stumbled across this post when trying to find a solution for the same issue on my M1 Air connected to my LG 32" Ergo 4k monitor. Even after 11.2 update. Scaling is not saved and desktop frame shrinks to about 2/3rd size after waking from sleep over USB-C. Spoke to Apple and one of their suggestions has worked for me;

Go to: /Library/Preferences/
Delete files: com.apple.windowserver.plist and com.apple.windowserver.displays.plist


Go to: ~/Library/Preferences/ByHost/
Delete files: com.apple.windowserver.XXXXXXXX.plist and com.apple.windowserver.displays.XXXXXXXXXX.plist

Empty trash. Restart.

So far, I can't replicate the issue again. Fingers crossed this holds, otherwise, back on the phone with Apple engineering team.
Well, this is a whole heck of a lot easier than rebuilding an M1 Mac from scratch.

Update: My problem seems to be fixed. Wake from sleep screen resolution has behaved impeccably since trashing the prefs. It’s been 24 hours now.

Thank you! Fixed the random resizing problem for my BenQ PD2720U connected over Thunderbolt....

With my old 1080p monitor, it used to have yellow tint - but only when the macbook was also open. When I closed it, the external monitor's yellow tint went away
Yeah my issue that I had originally with yellow tint is back after clearing those settings. However the resolution is staying fixed on what I set it at. I'm trying a different color profile to test if it's the monitor's built in color profile causing an issue when waking from sleep or after the monitor was off.

Did 11.2.2 fix the yellow tint when waking up screen?

Did it fix the resolution issues of resizing the external display scaling when waking?

I can't comment as I haven't experienced this issue.



This issue was fixed for me by trashing some prefs as described earlier in this thread. The fix has persisted in 11.2.2.
Yeah I had done the same but it eventually reverted back in my setup to blowing the resolution out of proportion. Currently my fix is to set it to prevent sleeping and engage a screensaver instead after 5 minutes.

Well, I have the screensaver at 10 min, and the display at 20 min. I have "Prevent Sleep" on too, because I keep Mail running 24/7 to apply all the rules I have stored.

I will try running without "Prevent Sleep" for a while and report back.

I’ll try again with 11.2.2 and see. I had turned off the option for turning the screen off so the screensaver runs 24/7.

I had no wake-from-sleep resolution issues while running without "Prevent Sleep" for a day.

I did have one instance of a green screen followed by an automatic reboot, though. I've not seen that before.

Post boot, I was promoted to file a report:

SOCD report detected: (AP watchdog expired)

Looking around online, that seems to be associated with an external drive. I have a Crucial X8 connected via USB C.

I have now returned to running my chosen config with "Prevent Sleep" back on.

Dear Community, dear ZiBart,
I had the same issues with the LG UltraFine 32UN880-B Ergo Monitor, in addition to the steps provided by ZiBart I had to disable the HDR option as well to make it work.

I'm on 11.5.1 and still having this issue. In fact it's worse now than a few updates ago. Tried deleting the window server plst files and this did not make any difference unfortunately.
Really hoping that Montrery will finally fix this bs.

I have a really annoying issue.... I plugged in my LG monitor via hdmi and an adapter. Worked fine. I then switched to usb c on the same monitor plug into usb-c port on the mac which worked fine. Then when going back to hdmi it no longer works. If I delete to colour profile i see it come back when i plug in the monitor. It also has a speaker and I can see in sys prefs sound the monitor there just nothing displays. If I boot into system restore mode the monitor works. I've tried deleting the plist file and rebooting but that doesn't work. Reinstalling fixes the issue also. There must be a file somewhere that is retaining the settings because if I plug back via usbc it remembers it's position and the fact i set it to rotate 90 degrees. This software https://fsmonitor.com/ shows you what files are being edited when doing things in the gui hence why i found the plist file and googled that and came across this thread, but I've deleted most plist i can see being changed but it still remembers to rotate 90 degree option and it's position in arrangement.

I had my Mac Book Air Display replaced under AppleCare! The old one was starting to fail and it only took them less then a week tom repair it! I give it to Apple for very quick service!
