UHD 4K video playback on PC: I have audio but no video!

[LP0779]

I recorded videos recently (in UHD 4K) and transferred them to my PC. When I attempt to play them back I can hear the audio but I get no video! Do I need a codec for this?

Maybe, try VLC, that application normally has most of not all codecs needed.

+1 for VLC player.

Maybe your graphic card won't handle 4k?
