144Hz Test
Verify your monitor is actually running at 144Hz. Test if your refresh rate is correctly set and your display is using its full speed.
This test uses requestAnimationFrame timing to estimate your display's refresh rate. Close other tabs and apps for the most accurate result. Browser throttling or V-Sync may affect the reading.
How does this test work?
A 144Hz test uses requestAnimationFrame timing to estimate your display refresh rate. If it shows ~144 FPS, your monitor is running at 144Hz. Lower values mean your refresh rate setting may be wrong.
How to use the 144Hz Test

Camera, microphone, keyboard, mouse, and controller inputs are processed locally and never leave your device. DeviceKit does not use analytics cookies or tracking scripts.
Browser note: Some hardware values are estimated because browsers limit direct access to device hardware for security and privacy reasons. Results may vary slightly between browsers and operating systems. For the most reliable measurements, use an up-to-date version of Chrome or Edge on a desktop computer.
Frequently Asked Questions
Why does my 144Hz monitor show 60Hz?+
Check your display settings in Windows/macOS — the refresh rate may default to 60Hz. Also verify you are using DisplayPort or HDMI 2.0+ cable, as older cables cap at 60Hz.
Does my GPU affect refresh rate?+
Yes. Your GPU must support the resolution and refresh rate combination. Integrated graphics may not support 144Hz at high resolutions.
