The refresh rate is the number of frames per second your monitor can display. Hertz frequency is used as the measurement at which the screen is redrawn.
Dynamic refresh rate is a new feature that can be found in Windows 11 on supported devices. Like the name suggests, DRR lets your device set the refresh rate dynamically. This means that Windows 11 will seamlessly switch between a lower refresh rate and a higher refresh rate based on what you’re doing on your PC. This helps to balance performance and power consumption. For example, with a Dynamic (60 Hz or 120 Hz) mode, your display will refresh at 60 Hz for everyday productivity tasks, such as email, writing a document, and so forth to conserve battery life. It will then seamlessly switch to 120 Hz for tasks such as inking and scrolling, to provide a smoother and more responsive experience.
To use DRR, you’ll need a laptop with a display that supports Variable refresh rate (VRR) and a refresh rate of at least 120 Hz.
Additionally, DRR requires a graphics driver (WDDM 3.0) that supports it (available through Windows Update). Microsoft is working with their graphics display partners to bring updated graphics drivers that support DRR to the Windows Insiders Program. Therefore, some people might need to wait a little longer to use DRR.
This tutorial will show you how to enable or disable Dynamic Refresh Rate (DRR) for a display for all users in Windows 11.
