Hi Ernest,
Here are some options How to find Troubleshoot Display Issues in Windows 11
Use the Built-in Troubleshooters
Press Windows + I to open Settings.
Go to System > Troubleshoot > Other troubleshooters.
Scroll down and look for:
Video Playback – helpful for screen flickering or playback issues.
Hardware and Devices – useful for detecting problems with display adapters or external monitors.
Click Run next to either one to start the process.
Check Display Settings Directly
Go to Settings > System > Display.
Here, you can:
Adjust Display resolution and scale.
Detect or rearrange multiple displays.
Change refresh rate under Advanced display settings.
This is often the fastest way to fix common issues like blurry text, incorrect resolution, or missing monitors.
Let me know how it goes, Happy to help!
