Are the two monitors different resolutions, the one being stretched lower than the other. So when it sleeps and wakes it assumes primary monitors resolution on both and over scans on the lower resolution one?
have you tried changing the display location settings?
like making the 4k #2 and moving it to the left position?
I’m sure it sounds dumb, but have you adjusted your display settings? ever? changing something will probably just recreate the config to a new version.
Yes, I’ve messed around with the settings trying to find a solution before, didn’t work
I might’ve tried this when I was messing around in the settings but I reverted it back to normal if I did because it would feel too weird to move my mouse to the left to get it on the right screen and the other way around to get it on the right screen. It would be something I wouldn’t get used to or enjoy doing
if you change or move the location of the monitor (#2 on the left in the display settings window) your mouse will move over to the correct monitor. if you set the 1440p monitor to the right location and have it as #1, the display manager will have your main desktop on the right monitor. while your secondary monitor will be the 4k on the left.
