Defective pixels are pixels on an LCD screen not performing as expected. The pixel is failing to reproduce light levels correctly.
There are three different types of defective pixels:
- Hot pixels (always on)
- Dead pixels (always off)
- Stuck pixels (one or more sub-pixels are always on or always off)
Defpix - Defective (dead) pixels tester is a free program that can help you with checking for defective pixels on your LCD screen. The program simply shows these colors - red, green, blue, white and black - over the whole surface of the screen. Defpix requires no installation and supports multiple monitor systems.
