playing 4k, black screen

[butterflies]

Hi,
I want to play, maybe also edit, 4K on my older PC.
-CPU i7 4820K CPU 3,70 GHz
-MB ASUS P9X79 Deluxe
-GPU Nvidia Geforce 210
-RAM 16 GB HyperX

I have replaced the GPU with a MSI Geforce GTX 1060, hoping that that would be enough. If I watch specs on the internet, it should be OK, but I get a black screen (with sound!) when I play 10bit or 8bit, 3840*2160 or 4096*2160, 29.97 fps MOV files, total bitrate 150Mb,from my Panasonic GH5. It does this in several video players, such as 5Kplayer, quicktime and also within videoeditors. Video plays with sound but black screen. Also thumbnails in Windows Explorer don't show preview. I am running Windows 10. Is there anything that I could do or check before I invest in more hardware?

Thanks,
Rob

You most lilkely need a certain codec to play whatever you are playing.

So, you think the hardware is fine?
Can you help me to start searching in a direction? What sort of codec?

PotPlayer is my go to video player (above VLC). Can play anything and had success with 4K content thru that where it gave issues in others.

Have you tried downloading and trying VLC media player? Perhaps Divx player?

Also what connection are you using between video card and monitor? Hdmi or display port?
