SDR content brightness revert to 0 after monitor HDR status change

I'm currently running windows 11 OS build 22000.282, using Odyssey G9 monitor from Samsung showing as LC49G95T in 'Settings-System-Display-HDR'.

After use HDR option turned on, my monitor blacked for a few seconds, then at the top left corner it shows 'DisplayPort1 (HDR)', then my screen slowly getting dimmer and dimmer (while I'm at desktop and only Settings opened). Changing SDR content brightness slider is indeed working, and I can make SDR content looks as bright as before HDR turned on. But if I try to launch a game doesn't support HDR or Auto HDR, for example Rainbow Six: Siege, my screen blacked few seconds and top left corner says 'DisplayPort1', my game looks normal as in SDR mode.

Then when I close the game, my screen blacked and it goes back to 'DisplayPort1 (HDR)', and slowly getting dimmer and dimmer, the brightness at this point is the same as the SDR content brightness slider in HDR settings moves all the way to 0.

When I check in the settings, the slider keeps at the spot last time I configured, but if I move it a little, the brightness changes to set value. This option is currently broken for me, as every time my monitor goes from non-HDR to HDR, I need to move the SDR content brightness slider again to make it work.

 

Windows 10 HDR problems in full screen.

Hello moderator

1. Its all the games I own that don't support HDR10. Basically when I full screen on a non-HDR game, the screen goes black for a few seconds and HDR gets disabled and all the colors looked washed out (Like its in SDR)

I took 2 screenshots, One is in window mode, the other is in full screen

Windowed mode (HDR on) : imgur.com

Full screen mode (HDR off) : imgur.com

2. Yes SDR looks washed out. I want to play my games in full screen and in HDR. Playing in windowed mode is a nightmare

3. I know because the monitor goes black for a few seconds and all the colors look washed out (As shown in the screenshots)

Sadly the fixes did not work

I updated the GPU drivers via GeForce Experience app.

My Monitor does support 4k HDR10

I tried lower the resolution and the refresh rate but that did not work.

Here is a video of my problem

YouTube Link :

Time Stamps :

0:00 HDR mode is on everything looks fine (In the video, when it looks high contrast, that means HDR is on)

0:35 I full screen the game. If you notice the high contrast is no longer there, the colors are washed out

0:46 I disable full screen and HDR mode is back on

*HDR looks high contrast, Ignore that, that's just the video itself.

Im also using windows 10 64bit 1809

 

HDR and black lines on desktop

Hi DeadlyMercury,



Welcome to Microsoft Community.



I would like to confirm some information with you.

• Does the problem only occur when HDR is enabled?
  
• Can you provide specific system version information and test games? Type winver in the Search Box to get detailed system information.
  
• When you play in full-screen mode, do you still have the issue?
  
• What is the specific hardware information for your device?
  
• What is a dedicated desktop? Can you elaborate?
  

Maybe you can try to reinstall drivers first.

For HDR content, please refer to the official link for details.
