Windows 10: I have a 4K monitor that supports HDR, how do i avoid the screen from becoming gray when...

I have tried the Windows HDR setting and i must say i am impressed when it works, which happens rarely. My intentions with HDR is to enjoy movies in brighter and more amazing colors, but there is a weird problem that ruins that fun.The problem is as following: my 4K screen when viewing a HDR video on VLC player or Kodi will only stay in HDR mode if i play the video in windowed mode or hover my button over a clickable link in Google while the movie is in fullscreen. Why do i not use the included media players? They don't work with my videos which are MKV. I know for sure that the problem isn't

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?

 

HDR Streaming grayed out in windows 10

Hi Mohammed AlJasim,

We determined the issue and found out that your computer specs and graphics card are highly capable of enabling HDR and running a 4K video.

Since you've already tested this on Sony TV and its perfectly working fine, we suggest that you
contact your other TV manufacturer’s support team (which is
BenQ) directly for confirmation if this TV is really capable for
streaming HDR videos in Netflix or not.

To know how to contact them, you can visit this link:
BenQ Support.

Netflix has a feature to auto-detect the capability monitors or TVs if they can stream HDR videos or not.

Please respond to this thread to let me know how the issue progresses. Similarly, if you have more questions, please inform me by replying to this post.

 

how do i get 4k uhd hdr to work in windows 10 ver 1803 windows will not recognize 4k uhd hdr 2160p monitors or 4k uhd hdr nvidia geforce gpu

That's not a feature of Windows. It's a feature of your graphics card and your monitor.

Does your graphics card support 4K UHD HDR on Windows 10?
