To set up a high-refresh-rate monitor on Linux, select it in your desktop’s display settings, choose a supported refresh rate, and apply the change. Menus vary by desktop; available modes depend on the monitor, GPU, resolution, and cable or dock.
Check the monitor manual or on-screen display for rates supported at your chosen resolution and input. Some high rates work only through a particular port. If the mode is missing, connect directly to the GPU when possible and check the cable, adapter, and dock.
Use the monitor’s native resolution. With multiple screens, select the high-refresh monitor and configure it separately; mirroring can restrict available combinations. The examples below use 2560 × 1440 at 144 Hz.
If the menu path differs, search the application menu for Displays, Display, or Monitor. Select the screen, choose a rate, and apply it.
Open Activities, search for Displays, and select your monitor. Choose a value under Refresh Rate and click Apply. Confirm with Keep Changes if the picture is stable; otherwise, GNOME restores the previous mode after about 20 seconds.
Open System Settings > Hardware > Display and Monitor > Display Configuration. Select the monitor, choose a rate, and apply it. Confirm the change only if the screen remains readable. Wording can vary by Plasma release.
Open Settings > Display from the applications menu. Select the target monitor, choose a value from Refresh rate, and press Apply.
Open Control Center > Displays. Select the monitor, choose its refresh rate, and apply the change. Some distributions place the launcher in a differently named settings menu.
Open Preferences > LXQt Settings > Monitor Settings, select the screen, choose a rate, and click Apply. The utility is lxqt-config-monitor. LXQt says it is not currently supported under wlroots-based Wayland compositors; use that compositor’s display settings instead.
Open Budgie’s settings app and search for Displays. Select the monitor, choose a listed rate, and apply it. The display panel name varies by Budgie release and distribution; confirm the change if prompted.
Keep a new mode only if the image is stable and readable. If the screen goes blank or distorted, wait for the countdown or choose Revert. Then check that the intended monitor still shows the selected resolution and rate.
A 144 Hz setting does not force an app to render 144 frames per second; frame rate depends on the app, GPU, and its settings.
G-SYNC or VRR is separate from the fixed refresh rate. Set the monitor’s mode first. If the monitor, GPU, driver, and compositor support VRR, enable it through the control your desktop or driver provides. NVIDIA’s current setting is named AllowVRR; the older AllowGSYNC name is deprecated. NVIDIA notes that nvidia-settings has limited functionality on Wayland, so its older OpenGL Settings checkbox is not a universal Linux step. If no VRR control appears, check your compositor and driver documentation.
