Can't play 4K video on 4K TV

Bought a new TV yesterday that supports 4K, but every time I try to change the display resolution to anything over 1920x1080 it just goes back to 1920x1080. If I try to play a 4K film it displays a blank screen.

In the logs I see this:

Have you configured the GUI as 1080p60 and set “Adjust Refresh Rate” to “Start/Stop”?

Yes, that is how it is configured.

Than please upload debug enabled logs so that we can check why it might not work

Try setting Force 422 colour subsampling in Settings->System->Display.

What is the make/model of the TV?

It’s a Panasonic TV, but I have fixed it by changing the HDMI cable between Vero and amp.
