Just Audio and a Black Screen for 240fps videos

When I play a 240fps Video there's just Audio... No Video at all... I'm running Windows 10 x64... And...

Please help...

Could you give me a link to such a video?

If you play such a file on a 60Hz screen, then 75% of the decoded frames will get dropped. But it should display video.

Try with a different video renderer:
MPC-HC options > Playback > Output > EVR-CP
