In HDR video games, the increased color range and brightness compared to SDR games gives you a more detailed and immersive gaming experience on your Windows PC. When you’re playing HDR games, you’ll see all the details in them—ranging from everything in the dark shadows in dimly-lit rooms to amazing brightness and reflections on things in those bright sunny scenes.
Though many newer games are developed for HDR, some older games are SDR only, such as games that use DirectX 11 or DirectX 12. But with Auto HDR, that changes. When you turn on Auto HDR, the color range and brightness is automatically increased to HDR. It’s a feature that lets you play and see your older games in a new light with HDR on your HDR-capable display. All you need to do is turn on Auto HDR.
To turn on Auto HDR
Select the Start button, then enter settings. Select Settings > System > Display.
If you have multiple displays, select your HDR-capable display at the top.
Turn on Use HDR, then select More options (>).
Turn on Auto HDR.
