To change a refresh rate in Windows 11, open Display Settings, then Advanced display. Plugable emphasizes choosing the intended monitor in the display menu before selecting a rate. This matters in a multi-monitor workspace because the available choices can differ from one screen to another.

If a desired option is missing, check the full connection: graphics hardware, dock or adapter, cable, monitor, and resolution. Some higher refresh rates require reducing resolution. The operating system can only offer combinations supported by the connection, so a monitor's advertised maximum does not guarantee that mode through every dock.
