NOT FIXED - Black Screen HDR After Adjusting Volume 1803, 1903, 1909, 2004

Same here...HDR now working with full screen and new nividia drivers.

I was just writing to say I was having the same issue but it seems to have stopped at least for me.

The only recent change was there was a Nvidia driver release yesterday (Driver Version 451.48) which I installed this morning.

I've tested it in Shadow of the Tomb Raider and in Command and Conquer Remastered with HDR on via windows and in the case of Tomb Raider enabled in game. The volume overlay appears but no black screen.

I hope this is a resolution to the problem for everyone and I'll post back if the problem recurs.

The original post I was writing is below which contains my relevant specs and the problem I was having.

Just wanted to add that I have the same issue.

With HDR enabled in a game, changing the volume causes a 2sec approx black screen before returning to the game.

Disabling HDR prevents this from happening.

Does not occur on windows desktop if HDR is enabled there and volume is changed but only in games.

When HDR is enabled in windows it seems to occur even if the game itself does not utilise HDR for example Command and Conquer Remake.

I've tried 3rd party apps to remove the volume overlay but the problem still occurs.

I have tried varying refresh rate from 144Hz down but HDR seems to be the only trigger.

What's happening with this? Has Microsoft replied? What was the point of buying a HDR display if Windows can't handle the pressure of 10 bits of color?

I should add that for UWP games, it's really bad, because not only does the volume do it, but also moving the mouse to the top of the bottom of the screen also causes it, because UWP games have TitleBar and TaskBar overlays that pop-up, they can't be disabled. 

I have suggested to the WinUI team that there needs to be an API to disable these popups. But that's a separate issue. It's just a feature that would help UWP games.

So I can't play Minecraft or No Man's Sky for example in HDR because this is happening constantly.

Unfortunately the mouse trail doesn't work for me. My guess is, for games that use a custom pointer, it doesn't work.

So after a few hours I've found a very easy fix that works 100% of the time for this issue.  I should have realized it sooner but oh well. All I did was go into Game bar (Windows+G) and enable the overlay for Performance. That's it. It also seemed to work with the party chat overlay, too. It seems like any Windows 10 overlay with the "modern" design or UWP APIs (volume, music, game bar, etc) will do the trick, so I kept it simple with the performance overlay and now I've got 100% HDR in full screen on PUBG.

Thank you SO much! Only fix that works so far!! Only issue is that I noticed odd FPS stuttering issues when it is pinned :/ and no it is not because my system cannot handle HDR, because it happens even on very light games.

I noticed that on mine, too, but it seems to be intermittent and sometimes just goes away completely. I'm considering it a small price to pay since I can use HDR now. I noticed the stutter is a lot better if I use the smaller option of the overlay that doesn't show the graph, so maybe try that. If you think the constant updating of the Performance overlay is causing your stutter, join an Xbox party and turn on the overlay for party chat because that also fixed it for me.

I assume this will also fix people who are having problems with HDR turning OFF when they use the volume overlay, although maybe this will just kill their HDR completely since their symptoms seem to be the reverse of mine. Either way, it seems like Windows HDR doesn't play nicely when modern UI elements go on and off the screen.
