Once part of the Insider Program (Dev Channel), if your PC monitor is already configured to use HDR, you will automatically receive the Auto HDR PC gaming experience. Otherwise, to explicitly enable/disable Auto HDR, look no further than the Windows HD Color Settings page.
Enabling
- Open Settings then go to System->Display
- Click the Windows HD Color Settings link
- Scroll down and make sure that the Use HDR toggle is On
- Keep scrolling and you will find the Auto HDR toggle. Flip this to On as well and that’s it. It’s that simple.
Disabling
- Open Settings then go to System->Display
- Click the Windows HD Color Settings link
- Scroll down and you will find the Auto HDR toggle. Flip this to Off.
Splitscreen mode!
Want to see how awesome your 1000 nit HDR monitor looks when displaying Auto HDR content? Well, we have a cool little “only for development and evaluation” secret feature for you! You can enable a splitscreen mode where the left side shows the original SDR content and the right side shows the Auto HDR upgraded content.
This is only for advanced users but if you want to give it a go, here’s how:
- Open an admin command prompt
- To enable splitscreen, run the following command:
reg add HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers /v AutoHDR.ScreenSplit /t REG_DWORD /d 1
- To disable splitscreen, run the following command:
reg delete HKLM\SYSTEM\CurrentControlSet\Control\GraphicsDrivers /v AutoHDR.ScreenSplit /f
