HDR support for windows 11

Hi Nadeem. I'm Greg, 10 years awarded Windows MVP, here to help you.

I would contact LG Support which is included with the monitor purchase for at least the first year, during which they must get it working properly or repair or replace it under warranty.

Windows 11 HDR issue

Hi all,

Having an issue when i turn HDR on through my new machine running Windows 11 which is causing the screen to look like the image below.

The monitor is a Dell G3223Q 4k HDR, which ive hooked up to my old rig (Windows 10) and the HDR worked fine. GPU is 7900XTX Phantom.

Has anyone encoutered this before in windows 11? I'm out of ideas.

I've tried:

Eliminating monitor issue by running it with another machine

Installing windows 10 monitor drivers and updating firmware

Different cables (DP & HDMI)

Different Color Profiles in windows

Different monitor OSD settings



Please help, thanks.

 

Windows 11 is changing my screen brightness while I am actively using Apps

Could you confirm if HDR is enabled on your system? If not, To enable HDR and Auto HDR in Windows 11, please follow these steps:

1. Enable HDR in Windows 11:
   
   • Navigate to Settings > System > Display.
     
   • Toggle on "Use HDR" under the "HDR" section.
     
2. Enable Auto HDR:
   
   • Within the same Display settings, toggle on "Use Auto HDR".
     

Once HDR and Auto HDR are enabled, you'll notice the "SDR content brightness" slider under the HDR settings. Now, proceed to adjust the SDR content brightness slider:

1. Adjust the SDR Content Brightness Slider:
   
   • The SDR content brightness slider regulates the brightness of non-HDR content, such as the desktop and file explorer, when HDR is enabled. This adjustment may potentially resolve the issue you're facing.
     

If the issue persists after these adjustments, you may consider the following troubleshooting steps:

• Connect a different monitor to your PC to determine if the issue lies with your monitor or your PC.
  
• Alternatively, if you're experiencing significant difficulties, reverting to Windows 10 could be an option to explore.
  

Please let me know if you require any further assistance or clarification.
