Mouse Tester
Test buttons, scroll wheel, double-clicking, and sensor accuracy.
Button Check
Click any button on your mouse.
(Right click won't open menu here)
📊 Movement Stats
↕️ Scroll Wheel
Scroll up and down to test.
⚡ Double Click Check
*Chatter = Clicks faster than 80ms.
*Double Click = Within 500ms.
🎯 Drag & Drop Sensor Test
How to Test Your Mouse
- Buttons: Click every button (Left, Right, Middle, Side). The visual mouse should light up correspondingly.
- Scroll Wheel: Roll the wheel up and down. The bar should move smoothly without jumping erratically.
- Double Click: Click the "Click Me Rapidly" button. If the "Double Clicks Found" counter goes up when you definitely clicked only once, your mouse switch is failing.
- Sensor Test: Use the Drag & Drop test. If the box "drops" while you are still holding the button, your mouse may have connection interruptions.
Common Problems & Fixes
- Double Clicking Issues: This is usually caused by static buildup or switch oxidation. Try blowing warm humid breath into the gap under the button, or use contact cleaner.
- Scroll Wheel Jumping: If scrolling down sometimes jumps up, dust is likely trapping the encoder. Compressed air often fixes this.
- Cursor Lag: For wireless mice, move the receiver closer (use an extension cable). For wired mice, check if the sensor lens is clean from hair/dust.
Common Mouse Problems & Solutions
Why is my mouse double clicking on a single click?
This is known as key chattering. It occurs when the micro-switch inside your mouse (usually Omron or Huano switches) oxidizes or wears out, sending multiple electrical signals for a single physical press.
Fix: Try blowing warm, humid breath under the mouse button or use a small amount of Contact Cleaner (like WD-40 Specialist Contact Cleaner) inside the switch. If that fails, the switch may need to be soldered and replaced.
Why is my mouse wheel scrolling the wrong way?
If scrolling down sometimes causes the page to jump up, the scroll encoder is dirty. Dust and hair can get trapped in the wheel mechanism, confusing the sensor.
Fix: Use a can of compressed air to blow out debris from the sides of the scroll wheel.
Wireless Mouse Connection Issues
If your cursor feels sluggish or disconnects, it is often due to interference. USB 3.0 ports can actually generate interference that disrupts 2.4GHz wireless receivers.
- Move the USB receiver closer to the mouse (use an extension cable if available).
- Keep the receiver away from USB 3.0 ports and routers.
- Check your battery levels. Low power often causes sensor skips.
What is Mouse Polling Rate?
Polling rate (measured in Hz) is how often your mouse reports its position to the computer. A standard office mouse uses 125Hz (8ms delay), while gaming mice use 1000Hz (1ms delay) or higher for smoother movement.
