Windows 10: HDR and fullscreen games on Windows 10 = Issues with notifications !

Hello everyone,


If someone from Microsoft could answer me, it would be super nice...


I found a lot of topics with the same issue on the xbox and windows forums with no answer.

Recently, I bought a brand new monitor with HDR. Everything is perfect except something: when I play a game from the xbox app or from other launchers, HDR works fine but when I have a notification or when I change the volume with my keyboard, my screen turns black during the notifs for 2 or 3 seconds...

I think the problem comes from the notifications: they are certainly not in HDR and that creates a conflict with HDR.


It's not a problem with the Xbox app only but with Windows10 because this issue also appears with notifications from others launchers and my volume button while in fullscreen.


I don't have this problem anymore when I disable HDR but I want to use HDR!


All my drivers are updated. My graphic card as well.

Please help me.


Have a good day, wherever you are and long live Microsoft.

:)

 

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.

 

Turning HDR makes color washed out and dull. Fullscreen in games ignores color settings.

I just bought a vesa certified hdr400 monitor and when I turn on windows HDR it looks more like the gamma just got cranked up. I can go turn the contrast up in nvidia control panel and it sort of balances out, but when I go fullscreen in games it lookes
pale and washed out as if I never made adjustments. The games work well with HDR in windowed, but not windowed borderless or fullscreen. Games I've tried this with include Doom eternal and Sea of Theives.

I'm running a 2070 super on the most recent graphics driver. Windows is up to date.

 

Notifications while fullscreen playing a game.

Chrome recently changed their notification settings to windows action center.

I now get notifications while fullscreen playing a game.

Is there a way to change that where I still get notifications but doesn't interfere while I'm playing a game?
