Windows 10 will add Auto HDR to over 1,000 PC games

High Dynamic Range (HDR) is on its way to over 1,000 PC games, courtesy of a new feature that Microsoft is testing out. Auto HDR is already available on the Xbox Series X and Xbox Series S, and now it's on its way to Windows 10. The Auto HDR feature is now available on Windows 10 build 21337 or above, which is available to Windows Insiders in the Dev channel.

Microsoft outlines the new feature in a DirectX Developer Blog post:

While some game studios develop for HDR gaming PCs by mastering their game natively for HDR, Auto HDR for PC will take DirectX 11 or DirectX 12 SDR-only games and intelligently expand the color/brightness range up to HDR. It's a seamless platform feature that will give you an amazing new gaming experience that takes full advantage of your HDR monitor's capabilities. The Auto in the title implies how easy it is for you to enable the feature; a simple settings toggle flip will let you turn the feature on and off.

Auto HDR will work with over 1,000 DirectX 11 and DirectX 12 games, greatly expanding the library of PC games with a form of HDR.

Microsoft shares an image as in example comparing Gears 5 with SDR, Auto HDR, and native HDR.

Gears 5 has a native HDR experience, so as you'd expect, it is the best of the bunch. That being said, the Auto HDR experience looks much better than the SDR one.

To appreciate this Auto HDR, you'll need a monitor that supports it. Luckily, many of the best computer monitors support HDR.

If you aren't a Windows Insider, you can easily join the program. Just be aware that you'll be using prerelease software, so you may not want to run it on your main PC.
