Mouse tests
Checks for the ways a mouse usually fails — a dead button, a switch that double clicks, a polling rate or DPI below its setting, a wheel that jumps — plus a click speed test and a troubleshooter for a mouse that is not working at all. Everything runs in the browser.
Mouse Test
Check every button, the scroll wheel, tilt and side buttons — with a pass or fail.
TestDouble Click Test
Find out if your mouse is double clicking — and whether drags drop while you hold.
TestMouse Polling Rate Test
Measure your mouse polling rate in Hz — 125 to 8000 Hz — and check it matches the setting.
TestScroll Wheel Test
Catch a jumping scroll wheel, count every tick, and measure scroll speed.
TestMouse DPI Test
Measure your real mouse DPI against a ruler or bank card — and check it matches the setting.
TestCPS Test
Click speed test in clicks per second — 1 to 60 seconds, with a check for a double-firing switch.
TestMouse Not Working
Cursor frozen, clicks dead, scroll jumping or wireless dropping — pick the symptom and fix it.
Which mouse test do I need?
| What you notice | Most likely cause | Test |
|---|---|---|
| One click opens things twice | Worn switch — its contacts bounce and send two clicks | Double Click Test |
| Drag-and-drop lets go by itself | The same worn switch dropping for a split second while held | Double Click Test |
| A side button does nothing, or the wrong thing | Remapped in the mouse software more often than broken | Mouse Test |
| The page jerks back while you scroll | Dust in, or wear on, the wheel encoder | Scroll Wheel Test |
| A gaming mouse feels less responsive than it should | Polling rate running below its setting | Mouse Polling Rate Test |
| The cursor is faster or slower than the DPI you set | A different DPI stage or profile is active | Mouse DPI Test |
| The cursor does not move, or the mouse keeps dropping out | Port, battery, receiver or driver | Mouse Not Working |
| You want to know how fast you click | — | CPS Test |
Before you blame the mouse
- Try another USB port, and another computer if you can. A fault that follows the mouse is the mouse.
- Reset buttons to their defaults in the mouse software — remaps and macros look exactly like a broken button.
- Check the operating system’s double-click speed and single-click-to-open settings before suspecting the switch.
- For polling rate, use Chrome or Edge: they expose raw pointer events, while other browsers may report your monitor’s refresh rate.
Using a result for a warranty claim
Double clicking and a jumping wheel are wear faults that usually get worse. A failed result shows the exact timing of each bad press or tick — screenshot it and include it with the claim. A clean result after cleaning is just as useful: it means the fix worked and nothing needs replacing yet.
