Mouse Test

Click and move your mouse inside the tester. The visualizer highlights each button—Left, Right, Middle scroll click, and Side Buttons (MB4 and MB5)—in real time while tracking click counts, double-click faults, polling rate (Hz), and DPI without installing any software.

Polling rate is how many times per second your mouse reports its position to your computer. Standard office mice poll at 125Hz (8ms), while gaming mice commonly poll at 500Hz (2ms), 1000Hz (1ms), and up to 4000Hz or 8000Hz for lower input delay and smoother cursor movement.

Unwanted double-clicking happens when the mechanical switch inside your mouse wears out or collects dust. The internal metal contact bounces when pressed or released, registering a second click in a fraction of a second (usually under 80ms). Our tester logs the exact millisecond delay between clicks and highlights unintended double-clicks in red.

DPI (Dots Per Inch, or Counts Per Inch) measures sensor sensitivity—how many pixels your cursor moves across the screen for every inch of physical mouse movement. To test your DPI, choose a test distance, line your mouse up against a ruler, and move it across that distance. The analyzer divides raw hardware sensor counts by your physical measurement to calculate your actual DPI.

To measure DPI accurately, your mouse movement cannot stop at the edge of your screen. Cursor locking (Pointer Lock API) keeps the sensor tracking continuously and disables operating system acceleration (like Enhance pointer precision), ensuring only pure, raw sensor counts are measured.

Most modern browsers natively recognize Button 4 (Back) and Button 5 (Forward). If they do not register, check your mouse configuration software (such as Logitech G HUB, Razer Synapse, or Corsair iCUE) to ensure those buttons are set to default mouse clicks rather than custom keyboard shortcuts or macros.
