Either way:
- Run sfc /scannow in elevated command prompt.
- Use ddu (display driver uninstaller) to remove GPU driver and reinstall. Trust, DDU can and has fixed obscure display errors for me.
- Try this registry edit or the ninth answer from this link
- Reset windows. It’s possible to do a soft reinstall and keep files.
It would be worth eliminating the cable first imo. Also reinstalls sound harder than they are. Even with a bunch of setting it usually only take me an hour or two these days and all it takes is shit starting to clutter or low space and I’ll nuke everything. Shit like ninite/Chris TTs winutils speeds it up a lot.
This bug (if I’m understanding your post correctly) has existed for 10+ years?
