What this test checks
How to use this test
Move inside the test area, press every button, scroll both ways, double-click, and drag across the pad.
What the results mean
Events show what the browser receives. A lower rate can be caused by rendering, power saving, or throttling.
Troubleshooting
Try another surface, port, connection mode, browser, or operating-system pointer setting.
Browser limitation
Browser event rate is an estimate and is not the mouse’s exact USB polling rate or DPI/CPI.
