HDR issue, can't enable despite support

Hi ConnorBaldczus,

Thank you for posting here in Community.

That sounds incredibly frustrating HDR issues can be tricky to pin down, especially when a game forces settings that Windows won’t even acknowledge. It’s baffling that your display is stuck in a pseudo-HDR state despite Windows showing it as off. I totally get why you're stumped, but let's go through some solid troubleshooting steps to try and get your display back to normal.

Troubleshooting Steps 1. Restart & Power Cycle

• Fully shut down your PC, then unplug it for a few minutes.
• If your TV has a power cord, unplug it too to ensure a full reset.
• Turn everything back on and check if the issue persists.

2. Reconnect HDMI Properly

• Since HDR is finicky with HDMI ports, double-check you’re using a high-speed HDMI 2.0 or better cable.
• If your TV has multiple HDMI ports, try switching to another one to see if it makes a difference.
• Ensure the HDMI cable is securely connected—loose connections can cause signal drops.

3. Override HDR in Nvidia Control Panel

• Open Nvidia Control Panel → Go to "Change Resolution".
• Select your TV and ensure the resolution is set to 3840x2160.
• Below resolution settings, see if the option “Use default color settings” is selected. If HDR is messing up colors, try using Nvidia’s “Use Nvidia color settings”.
• Set Output Color Format to RGB and Output Dynamic Range to Full.
• Apply changes and see if this resets your display back to normal.

4. Force Disable HDR in Windows Registry (Advanced Step) If Windows isn't reflecting HDR as enabled but the game forced it, you can manually disable HDR via the Registry.

• Press Win + R, type regedit, and hit Enter.
• Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
• Look for a key related to HDR settings. You may see something like DxgKrnl, HDR, or ScRGB.
• If you find an HDR-related key, try setting its value to "0" (which disables it).
• Restart your PC afterward.

5. Check Windows HDR Settings

• Go to Settings → System → Display.
• Find the "Use HDR" toggle. If it won't turn on, try changing your refresh rate under Advanced Display settings to see if it lets you enable it.
• Try toggling HDR in Windows again.

6. Check TV Settings (Limited Options but Worth Trying) Your TV might not have a direct HDR toggle, but it may have picture modes interfering with how HDR is processed.

• Look for Picture Mode and set it to Standard or Game Mode.
• If your TV has Local Dimming or Backlight settings, try adjusting them.

7. Force HDR Off in the Game Settings

• If the game keeps forcing HDR, you could force-disable it via config files (some games allow manual tweaking).
• Check for any third-party fixes related to HDR in that particular game.

Final Thoughts

If none of these work, it might be worth completely reinstalling your graphics drivers. Sometimes display quirks persist due to driver corruption. You can use DDU (Display Driver Uninstaller) to do a full GPU driver cleanup and fresh install.
