What this test checks
Test mouse buttons, pointer movement, vertical and horizontal scroll and additional button events directly in your browser.
InputAnalyzer processes test events locally and does not upload your raw inputs or result values.
How to run the test
Enter the test area
Start the test and move the pointer inside the panel so interactions are separated from normal page controls.
Check buttons and movement
Click the main, secondary, middle and available side buttons, then move in several directions.
Check the wheel
Scroll up and down and, if supported, test horizontal scrolling while watching the event log.
How to read the result
Observed signals, not artificial certainty.
Expected response
Each action produces the corresponding event once and released buttons do not remain active.
Irregular response
Missing buttons, repeated presses or wheel activity in the wrong direction should be confirmed in another application.
What this test cannot prove
What the browser cannot see
- Browser button numbers for extra controls vary, and drivers can intercept or remap them before they reach the page.
- This test cannot measure physical DPI, USB latency or guaranteed hardware polling rate.
- Results are browser-based estimates, not a physical hardware diagnosis.

Frequently asked questions
Short answers before you test again
Why is a side button not shown?
The browser may use it for navigation or the mouse software may remap it. Try the test area in another browser after checking the driver settings.
Can this test measure mouse DPI?
No. Browser movement is affected by operating-system scaling and acceleration, so it cannot reveal the mouse's physical DPI reliably.
