Check your Windows 11 refresh rate, select the correct display, and see whether Dynamic Refresh Rate is available for your hardware.
Open the correct display panel
Go to Settings > System > Display > Advanced display. If several screens are connected, select the one you want to adjust. Read the displayed resolution and refresh rate before changing anything.
Choose an available refresh rate
Use Choose a refresh rate to select a supported option. The list depends on the display and hardware. An asterisk beside a rate means selecting it will also change the resolution, so check both values afterward.
Understand Dynamic Refresh Rate
DRR adjusts the refresh rate to balance smoothness and battery use. Its toggle is in Advanced display when supported. Microsoft states that DRR needs a display supporting variable refresh rate and at least 120 Hz. A missing option is not, by itself, evidence that Windows is broken.
Compare in a normal task
Our suggestion is to test the same activity before and after: scroll a long page, move a window and work in your usual document editor. Keep the resolution unchanged where possible so you are comparing refresh rate rather than several changes together.
If you use a laptop away from power, consider whether the smoother motion is worth any difference in battery runtime for your routine. A setting that suits a desk-based gaming session may not be the setting you prefer while reading on a trip.
Record a working setup
Write down the display name, resolution and selected rate once you find a combination you like. This is useful when reconnecting through a dock or moving between workspaces. If an expected option is absent, check the specifications for the display and the connection equipment before buying a replacement cable or changing unrelated settings.
