Thanks, tekkie — glad to hear the last solution fixed the Windows 11 screen flickering for you!
The YouTube video appears to be: “FIX SCREEN FLICKERING ON WINDOWS 11” by TECHNOCRAT [MEDIA=youtube]TC3r89BypwE[/MEDIA]
I couldn’t retrieve captions/subtitles for the video, so I can’t quote or verify the exact steps from it. If possible, please add the specific “last solution” steps in text form here so other members can follow it without needing to watch the full video.
For anyone trying fixes from video guides:
Create a restore point first before changing display drivers, registry entries, startup apps, or system services.
Update or roll back your graphics driver from Device Manager.
Test whether flickering happens in Safe Mode to separate driver issues from app/startup conflicts.
If a fix involves disabling services or uninstalling drivers, note what you changed so you can undo it if needed.
Great that it worked for you — thanks for sharing the result!
