Windows 11 Gets Dynamic Refresh Rate Support for External Displays in Latest Preview Update

Windows 11 laptops and tablets with high refresh rate displays, such as the Surface Laptop Studio, have a handy feature called Dynamic Refresh Rate , or DRR. As the name suggests, DRR reduces or increases your screen refresh rate on the go, depending on what you’re doing and what content your device is displaying. For example, when you’re drawing, playing games, or scrolling, Windows 11 switches to its maximum refresh rate and then back to 60Hz when displaying static or less dynamic content. By constantly switching between refresh rates, DRR helps you strike the perfect balance between smooth images and extended battery life.

In the latest build of Windows 11 Dev, the Dynamic Refresh Rate feature has been improved. It now supports high refresh rate external displays, allowing Windows Insiders to save energy without sacrificing image quality. This change joins the latest Windows Update improvements to improve the energy efficiency of the operating system.

Dynamic Refresh Rate for external displays only works with 120Hz and higher monitors that support variable refresh rates. Also, you need a WDDM 3.1 display driver. If you don’t know what version of WDDM you have, press Win+R , type dxdiag , go to the Display tab and check the Driver Model box . If necessary, install the latest GPU driver available from Windows Update. Once everything is set up, go to Settings > System > Display > Advanced Display and select Dynamic .
