Windows 10: My Surface tab freezes frequently when connected to a 4k display

I see the computer freeze frequently when connected to a 4k display, most often during any window resizing operation. This doesn't happen on Full HD devices though. It is not always, but it is easy to produce by doing a few resize operations.


Anything I am missing? I am connecting the display through the USB-C hub that supports HDMI.

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?

 

Does Miracast support 4K?

Hello,

We suggest that you check with the manufacturer of the 4k display device that you are using if it is certified to work with Miracast. If your display device is certified to work with Miracast, then check if your PC device supports Miracast. You may do so
by following the steps below:

• Click Start, then go to Settings >
  Projecting to this PC.
• Check if your device supports Miracast.

Regards.

 

Surface connection to external device

Hi Niveita,

The message that you received when connecting your Surface Pro to an external display may arise due to an incompatible display resolution. As an initial step to rule out any display rendering issues, we suggest that you change the
resolution on the Display settings. To do this, follow the steps below:

• Click on Start menu or the Windows logo.
• Click on Settings or the gear icon.
• Select System.
• Under the Display tab, click on the Advance display settings link.
• Set the resolution to 1366 x 768 or lower.
• Once you're done, check if the issue persist.

In the event that the issue persists, try changing the resolution under Control Panel >
Intel Graphics Settings and check if you encounter the same issue.

We'll appreciate if you can send us an update.
