Windows 11 can auto-adjust your monitor’s refresh rate to save power

Windows 11 supports the activation of a dynamic refresh rate (DRR) on monitors equipped with the relevant technology. When this feature is enabled, the operating system automatically adjusts the refresh rate to suit the user’s activity. For example, while the user is working with standard desktop applications, Windows maintains the refresh rate at 60Hz.

However, as soon as a game starts, Windows automatically increases the rate to 120Hz to ensure a smooth display. For Windows to offer this feature in its settings, the monitor must support a variable refresh rate (VRR) and be capable of a refresh rate of at least 120Hz.
