Do you still need assistance?

[Huddeij]

Yes, still not solved. I don’t know what to do

Is the PC’s graphics card 4K compatible? Can you set this resolution?
Is the TV full 4K or just 4K compatible?
Are you using a 4K compatible HDMI connection?

sorry guys, I’ve got nothing.

Any updates?

GOT IT!
It was the TV. Sony forces one to change the HDMI mode setting for each input individually from standard (default) to extended mode. Just found it and now it works fine.
If anyone else comes into this situation, you go to “Home” screen, then click on the gear in the top right. There you go to “watching TV” and then “external inputs”. There you’ll find the HDMI Input where you can change your inputs individually to extended. BANG, it works like a charm
