About Refresh Rate Test
A refresh rate test estimates how many times per second a screen is redrawn, measured in hertz. This page records the time of every animation frame the browser delivers for two seconds, takes the median gap between frames, and converts it to Hz. It also names the closest common rate, from 60 to 360 Hz. The result is the rate the browser is drawing at, which can be lower than what the monitor supports.
Questions about Refresh Rate Test
Why does my 144 Hz monitor show 60 Hz?
The test reports what the browser draws, not what the panel can do. Check that the refresh rate in your system display settings is set to 144 Hz, that the cable supports it, and that power saving mode is off. Some browsers also cap frames at 60.
Why does the result change between runs?
Frame timing shifts slightly with system load, so readings such as 59.9 or 60.1 Hz are normal for a 60 Hz screen. Heavy background activity or a hidden tab can lower the figure. Run the test again with the tab visible.
