VLC not working well --- Black screen for videos (and what I tried)

I use VLC since I installed Win10 last year; Never had any problems.

Suddenly all videos I ran in VLC doesn't contain image --- Only sound.

WMP (Windows Media Player) plays videos fine.

Thing I tried and didn't help:

• Reset all VLC prefrences.
• Updating VLC.
• Uninstalling and reinstalling VLC.
