Windows 10: HDR Issue - Playing games or fullscreen Youtube videos

I recently got an LG HDR compatible monitor. I run with HDR on and for the most part have no issues.


I have played 2 games since I got the monitor - Nier : Automata works fine, I also play an older game called Outland. Playing Outland is fine until I exit the game - the game seems to flip out of HDR and then re-enable it when I close out. The issue is that when the HDR is re-enabled the white point is not set correctly. White seems to be slightly pink/grey and the image has a slightly washed out look.


I am also seeing the same thing occasionally when I go fullscreen with a YouTube video. Randomly the display seems to lose connection and I will see a black screen with random blocks of colour and again the image being washed out when it sorts itself out.


Solving it is easy, I just go to Display Settings and switch off/on the HDR setting and then all is back to normal but that gets annoying quick.

HDR fullscreen problems

Version: Windows 10 17134

GPU: NVIDIA 1080 Ti (Driver 397.31)

Display: LG OLED 55" B6P

Problem: Windows HDR implementation barely works properly. Here's a list of issues I've seen so far:

1: SDR applications that are not exclusive fullscreen start in HDR mode, distorting the colors. If an OS overlay [such as the volume overlay] come up, the display will go blank until the overlay dissapears.

2: SDR applications that are exclusive fullscreen go blank. From what I can see, my display is in SDR mode, so I'm guessing there's a mismatch between Windows trying to output HDR content and the display receiving it. [And no, the problem is on Windows
end; the display can handle HDR just fine on other systems]

3: I've had a case where an SDR application, on exit, somehow resulted in the system HDR setting being disabled. I've also had another case where on exit the system is reporting its in HDR mode, but outputting SDR even on the desktop.

So in short: Windows is not managing HDR properly.

Hi Lin,



Thank you for writing to Microsoft Community Forums.



In order to get clarity on this issue and assist you with appropriate troubleshooting steps, please reply with the answers to the questions below.

1. What is the make and model of your computer?
   
2. What is the make and model of your both monitors?
   
3. As you have given multiple versions of Windows 10, is this issue occurring on multiple computers?
   

Not all displays are optimized for HDR. If you have two displays and move the HDR video onto a display that’s not optimized for HDR, you’ll get the appropriate standard dynamic range (SDR) as soon as new content starts to play.



To play streaming high dynamic range (HDR) video in Windows 10, your external display and Windows 10 PC needs to support HDR. To find the specifications for a specific PC or external display, visit the device manufacturer’s website.



It might be that one of your monitors doesn’t' support HDR, so I suggest you to refer
Display requirements for HDR video in Windows 10 and check
if your monitors support HDR.



You may also refer Stream HDR video on Windows 10 and
HDR and WCG color settings in Windows 10 and check if this helps.



We're looking forward to your response.

 

Youtube fullscreen shows taskbar (Chrome)

That doesn't work either. Its not just Youtube that does this on. I play World of Warcraft and many other fullscreen games, and the toolbar is showing up over all of them. Its a huge pain!*Confused
