Taking Surface Laptop Studio as an example, Windows 11 laptops and tablet devices equipped with high refresh screens can now get a practical feature - Dynamic Refresh Rate (DRR). DRR can increase or decrease the screen refresh rate according to the needs of the actual scenario, thereby achieving better battery life.
For example, when you are writing, playing, or scrolling, the Windows 11 system will switch to the maximum refresh rate, and when you are watching photos or low dynamic content, the system will drop to 60Hz. By constantly switching between refresh rates, DRR helps you achieve the perfect balance between smooth images and longer battery life.
The latest Windows 11 development version improves the dynamic refresh rate feature. It now supports external high refresh rate displays, allowing Windows Insider members to save energy without sacrificing image quality. This change will include the latest Windows update improvements, with the focus on making the operating system more energy-efficient.
For external monitors, the DRR function is only suitable for monitors that support variable refresh rates and refresh rates above 120Hz. Additionally, you need a WDDM 3.1 display driver.
If you don't know the version of WDDM you have, press Win + R, type dxdiag, go to the Display tab and check the Driver Model field. If necessary, install the latest GPU drivers provided by Windows Update. After setting up everything, go to Settings System Display Advanced Display and select Dynamic.
