Compare another source and another application before changing the account. If the player offers a documented hardware-decoding setting, make one reversible comparison and then restore it if it does not help.

Why this happens
A black video surface with continuing sound can involve the rendering or decoding path. The same symptom can also be source-specific, so one setting is not a universal fix.
Work through the steps
- Test a second known working programme.
- Check player updates and the supported Windows graphics update route.
- Compare the player's documented decoding option if available.
- Repeat the original source in the same window and display.
What to avoid
Avoid random codec packs and unofficial driver utilities. Do not claim every player exposes a hardware-decoding switch.
Know what changed
The comparison should show whether the picture changes with one rendering option or fails only on one source. Record app, graphics and display details if it persists.
