4 Things to Know About White Mousepads and Optical Sensors

Older optical sensors struggle with white mousepads in bright light These sensors track by taking micro-photos of the surface, and a white pad reflects ambient light back into the sensor, causing confusion.

Bright overhead light or a desk lamp turns a white pad into a strobe light This results in cursor jitter, random jumps, or the pointer stopping entirely.

Newer sensors handle white pads much better Most gaming mice after 2015 use infrared or have better light rejection, so they avoid these issues.

The fix is a dark or black cloth mousepad A black pad reflects less light, giving the sensor a cleaner image. Avoid cheap white pads if your mouse uses a red LED.
