If you have a monitor operating in high dynamic range mode, you can get a brighter and more vivid experience. So if your monitor supports HDR, you should turn it on as soon as Windows 11 starts to see OS visual design updates in the best light. It is easy to enable HDR if you upgrade to Windows 11 on an existing PC or download a Windows 11 ISO build for a clean install.
High Dynamic Range (HDR) makes your images or videos brighter, more prosperous and more detailed. If you have a more or less modern monitor, then we will explain how you can enable Auto HDR in Windows 11.
How to Enable HDR in Windows 11
1. Open the Settings app and then click on System> Display.
2. Click on the “HDR” column.

Can I Enable Windows 11 HDR on an Unsupported Display?
No, if HDR is not supported on your Windows 11 PC/Laptop, it is impossible to enable it as HDR is created by having a very high contrast ratio. Hence, it is impossible to enable HDR on a non-HDR monitor. If you turn on HDR by the registry or any other force allow trick, it will not work as hardware cannot provide the output and show the enhanced image.
Update December 2021: Microsoft has confirmed that some image editing programs might not render colours correctly on specific HDR displays if devices run Windows 11 21H2. Users are experiencing colour rendering issues due to a newly acknowledged Windows 11 bug. If your apps use Win32 APIs to render colours, it might not work as expected.
