Monitor Refresh Rate Test
All tools
Free
Measure your display's real refresh rate in Hz with live min, max and average frame timing and a smoothness demo. Free and runs in your browser.
Your refresh rate is estimated from the browser's animation frame timing. Keep this tab focused and in the foreground for the most accurate reading.

The bar below moves one screen width per second — it should glide smoothly at your display's refresh rate.
Browsers may cap animation frames in background tabs or on battery saver, which lowers the reading.
