Look at the spacing of incoming keyboard events. This gives you a view of browser input cadence, with a clear distinction from hardware polling rate.
Explore the spacing between physical key presses.
Tap different keys repeatedly to build an interval histogram. Held-key auto-repeat is excluded.
These are intervals between browser keydown events, determined largely by your typing rhythm. They are not USB/Bluetooth polling intervals and cannot reveal your keyboard’s hardware polling rate or Hz. Charts and statistics retain the latest 300 samples.
Focus the test and tap keys repeatedly. Inspect the average interval, median and histogram across multiple samples. The tool shows milliseconds between separate browser keydown events and excludes held-key autorepeat.
Hardware polling describes how often a device is queried. Browser keyboard events are generated only when input changes or software repeat occurs. Human tapping, macOS scheduling and browser processing affect the observed intervals.
Check the manufacturer’s documentation and connection mode. Reliable verification needs tools that can inspect the relevant device or transport reports. A short browser event interval does not establish a 1,000 Hz or higher hardware specification.
About the test, your keyboard, and that one key that won’t light up.
More answersNo. A browser does not expose the USB report schedule through ordinary keyboard events. This page presents event interval estimates, not a hardware polling certification.
That is usually the operating system’s autorepeat behavior. It should not be interpreted as the keyboard’s USB or Bluetooth polling rate.
