Hi Ethan. I'm Greg, 10 years awarded Windows MVP, specializing in Installation, Performance, Troubleshooting and Activation, here to help you.

2) The Display driver is so important here that merely updating it is sometimes not enough. So let's try everything possible to get it working correctly:
First make sure you have updated the Display driver from the PC or Display adapter maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC.
While there check also for newer chipset, BIOS/UEFI firmware (very important), network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu.
Remove the old driver using DDU
https://www.wagnardsoft.com/content/ddu-guide-t... if necessary installing in Safe Mode with Networking (so you have internet), or Safe Mode, accessed by one of these methods:

If this doesn't give you the latest or ideal driver for what you need, compare it to the driver offered by the Intel driver update Utility here:

or the Nvidia GeForce scanner here:

or the AMD autodect utility here:

For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver. You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.
Then you will know you've tried everything in addition to Windows Update drivers.
Adjust the screen resolution until it fits and looks best at Settings > System > Display.
3) Establish a Clean Boot to get rid of Startup freeloaders that can hog resources and cause issues by conflicting:

4) Run System File Checker/DISM in WIndows 11:

5) If that doesn't fix it then you can do a Windows 11 Repair Upgrade which reinstalls Windows while saving your files and apps in place, brings it up to the latest version by the most stable method, takes about an hour and resolves most problems:
