Online Mouse & Touchpad Diagnostics — Buttons & Scroll Testing

This web utility offers comprehensive diagnostics for mice and laptop touchpads, helping you detect faulty microswitches, wheel encoders, and tracking issues.

What the Tool Checks

Double-Click Bug Detector: detects erratic microswitch double-clicks on single keypresses (intervals under 80 ms).
Side & Auxiliary Buttons: validates Mouse4 and Mouse5 navigation buttons.
Scroll Wheel Encoder: checks smooth scrolling in both directions without frame skips or reverse bouncing.
Cursor Tracking: tests smooth pointer movement across an interactive canvas.

When to Use This Test

Use this test if file selection drops unexpectedly, windows close accidentally, scrolling stutters on web pages, or when verifying a new gaming mouse.

Technical Details

Web browsers cannot directly query physical hardware DPI (Dots Per Inch) or USB polling rates (Polling Rate Hz). Specialized desktop software is required for hardware DPI measurement.
