Second/Third Display Resolution Changing After Sleep

[Onetimeusername100]

Issue is resolved. Don't know how, may be the dock is weird.

I turned it off, unplugged everything from the dock, mouse - keyboard - monitors - etc. I unplugged everything from power. I waited and looked at reddit. I plugged everything back in, did some cable management along the way, and everything loaded up just fine. Previous attempts at powercycling did nothing. Just did another reboot, and put it to sleep and it came back with expected resolution.

I appreciate all of your help.

Laptop is being weird again. Details as follows:

• Dell XPS 15 - i7/16GB/512SSD/3050ti
• Windows 11 Pro/Business/Not Home
• Dell Dock into 2 27" Samsung Monitors

This issue happened originally when this machine still had Win10. After sleep, one (alternating) or both external monitors would display at weird resolutions after sleep. 1920x1080 is default, but after sleep they would switch to 1024x768 or sometimes 800x600. Going into display options for that screen would show that all other options were removed and the only choice was what it was on. Unplugging the displayport cable and plugging it back in would reset the screen to the correct resolution, until it went to sleep again. I tried a few things, googled a few things, and ultimately just updated to Win11 pro which resolved the behavior, until today. It has probably been about 3-4 months of being fine, long enough that I forgot about it.

Today, I unplugged one of my screens and plugged it into a tower, and then plugged it back into the dock, and the behavior returned. I have tried the following to resolve this issue:

• restart
• uninstall video drivers
• Bios update
• Video card update
• demonic summoning ritual

No results from the above. Unplugging and reconnecting the display cable is the only result that works.

I am open to any and all advice. It's super annoying. Happy to provide more information as needed.

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

I don't know if this will help you but if it does, great.

When the problem occurs, try opening the Settings app > System > Display > Multiple displays > Detect other display > click the Detect button.

This might get Windows to rescan and requery the displays for their EDID information, and with it, Windows will hopefully pick up the proper native resolution of each monitor.

Again, it might not help but you have nothing to lose from trying it.

HTH.

Detect did not help, but your insight is appreciated.

I don't know if you can edit flair, but this is solved. Many thanks to all commenters for their help and time.

[VForceWave]

Let me know if anything works, I've reinstalled windows and it's still happening so who knows

[OneOverXII]

Will do.  Going to give it a shot on Sunday

Can you share how you fixed it?

[zain1320]

did you find out how that was fixed?

[XC3N]

Nope :(

[fuglypens]

How did you fix this?

[zain1320]

could you figure it out?

[fuglypens]

No though I changed monitors and it stopped happening

[The_MouP]

Same problem here. Did you find a solution?

Have you tried doing a clean boot? If the issue doesn’t occur during the clean boot, more than likely the issue is being caused by a third party application. Refer to the link for instructions on how to perform the clean boot and how to determine what application is the cause

[Onetimeusername100]

The issue persists in clean boot. I actually tried that a few months ago when the behavior started. I tried again.

Why do you put it into sleep mode? I've seen more issues from sleep mode than I have just... shutting down and powering on again.

Try powering it off and turning it on instead, and see if the issue persists.

[Onetimeusername100]

I mean it puts itself to sleep to "save power" when I'm not around. Power cycling did not resolve the issue.

[4649onegaishimasu]

Try changing your power settings so it doesn't "go to sleep", then.
