Windows 10: 4k tv as monitor in Windows 10 resolution greyed out

I am trying to use a 4K TV with my surface pro 7. my problem is that when I change it to be the main display all options are greyed out so I cannot see what resolution it is set to, and it is not 4k.


When I change the settings so that the TV is used as an extended monitor the resolution is 4K, so I believe It is not a hardware problem.

Sony Bravia TV as HDMI Monitor -resolutions missing

Ah ha, Is your TV a 720 TV or a 1080 TV.

If you have a 720p TV, then it might not be capable of processing above 1080. That is why when you buy a TV, you buy a 720, 1080 or new 4K. Check your tv video settings on TV. But since it is a monitor, maybe it can.

I know a 720p TV can not display a signal from cable box of 1080, so you have to set cable box output to 720.

I also suggest to change the refresh rates. This might give you higher resolution settings.

 

Windows wont display 4k and HDR simultaneously.

I recently got a 4k HDR tv (Samsung UE43NU7100). I connect my PC with a normal HD monitor and the 4k HDR tv. When turning on HDR on my tv the resolution of the 4k tv (3840x2160) gets set back to normal HD (1920x1080) in windows settings. Windows is completely
updated, my AMD Radeon R9 390 8gb graphics card is up to date and supports and displays in 4k when HDR is off. My Xbox one X displays both 4k and HDR perfectly simultaneously. I use a high speed HDMI 2.0 cable. I have no idea why my pc does this and cant find
anything about windows not being able to do 4k and HDR at the same time. It also doesn't work if I only connect the tv instead of the monitor and tv. Any suggestion?
