Can´t stream/record at 4k?

Hello dear Community.
I have a problem. I have a PC with an ASUS GTX1050 TI, 16 GB RAM, 4-Core-I7 2.7 GHz and a Sony FDR AX-700 Camcorder.
I want to record/stream the camera input on my PC, but the Problem is, when I select 4k output on the Camera, OBS only shows a black screen. It works on 1080p but is laggy. I use the elgato Camlink 4K, and a full size HDMI-out for it. The GTX1050 ti is capable of 4K
Anyone else have a solution for this?
I tried the camera in 4K on my other PC with I9-10900k, RTX3090 and 64gb RAM and it works just perfect!

If you have more questions, I here to answer them

Chances are good that you're using an incompatible color depth on the Camlink 4K. At 1080p it supports 4:2:2 color sampling, but IIRC at 4K it can only do 4:2:0, so will fail and only show a blackscreen (or nothing) if you have a 4:2:2 color sampling method chosen.

Thank you, I will try it
