Mouse Test

How to Use This Test

1. Move your mouse over the test area to verify movement tracking and cursor responsiveness.
2. Click each mouse button (left, right, middle, side buttons) to confirm they register properly.
3. Scroll up and down with the scroll wheel to test smooth scrolling and click detection on the middle button.

What This Test Checks

This mouse tester provides a comprehensive check of all your mouse functions, helping you identify hardware issues or confirm a new mouse is working correctly.

• Left, right, and middle button click detection
• Side button (forward/back) functionality
• Scroll wheel direction and smoothness
• Mouse movement tracking and cursor position
• Double-click speed and registration

Troubleshooting

If you're having issues:

• Try unplugging and reconnecting your mouse, or replacing the batteries for wireless models.
• Update your mouse drivers through Device Manager (Windows) or System Preferences (Mac).
• Clean the mouse sensor on the bottom and ensure you are using it on a suitable surface.
• If side buttons are not detected, check your mouse software for button mapping configuration.

Diagnosing Common Mouse Problems by OS

Double-click issues (single click registers twice)

This is the most common mouse failure — the microswitch inside the button has worn out and bounces. The test above will show two click events for a single press.

• Windows: increase debounce via the mouse manufacturer's software (Logitech G HUB, Razer Synapse, Corsair iCUE) if available.
• macOS: System Settings → Mouse → Double-click speed (slowing it down is a temporary workaround, not a fix).
• Long-term fix: replace the microswitch (Omron D2F-01F is the standard part for most gaming mice) or use the warranty — most gaming mice ship with 2-year coverage.

Cursor jumping or stuttering

• Clean the sensor lens on the underside of the mouse with a dry cotton swab.
• Change the surface — optical sensors struggle on glass, glossy, or highly reflective surfaces. Use a fabric or hard plastic mousepad.
• Windows: disable Enhance pointer precision in Settings → Bluetooth & devices → Mouse → Additional mouse settings. This mouse acceleration causes perceived stuttering in games.
• Wireless mice: move the USB receiver closer or use a USB extension cable to reduce 2.4 GHz interference with Wi-Fi.

Scroll wheel skipping or scrolling the wrong direction

• Check your OS scroll direction setting. macOS inverts the default (Natural scrolling) vs Windows.
• Wheel encoders accumulate dust over years — compressed air through the wheel slot often restores smooth scrolling.
• Windows: Settings → Bluetooth & devices → Mouse → Scroll inactive windows when hovering over them — toggle off if scroll feels laggy.

Related Input Checks

Cursor stutter and input lag often aren't the mouse alone. If your keyboard also feels laggy, the problem is likely at the USB/driver level. On laptops with a touchpad and touchscreen, run the touchscreen test to rule out interference between input devices.

How to Measure Mouse DPI and Polling Rate

This browser test cannot measure DPI or polling rate directly — the browser only sees cursor deltas, not raw sensor input. Use these tools instead:

• Manufacturer software: Logitech G HUB, Razer Synapse, SteelSeries GG, Corsair iCUE all display and let you change DPI and polling rate (usually 125 / 500 / 1000 / 2000 / 4000 / 8000 Hz).
• MouseTester (open-source, Windows): plots polling rate stability and interval graphs.
• Polling rate checker sites: move your mouse in a circle as fast as possible — peak Hz equals your polling rate.
• Online DPI analyzer: move the mouse a measured distance (e.g., 10 cm with a ruler) and calculate pixels traveled divided by centimeters moved × 2.54.
