FAQs
How do I test a mouse sensor online? +
Move the mouse in slow straight lines and quick swipes while watching for skips, stalls, or unexpected jumps. Then compare another surface.
What causes mouse sensor skips? +
Dirty lenses, reflective surfaces, poor pads, USB hubs, wireless interference, and failing sensors can all cause skips. Change one variable at a time.
Should I buy a new mouse when the sensor skips? +
Only when skips follow the mouse across clean surfaces, ports, and receiver positions. Surface and connection fixes are cheaper first checks.
