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. It is used in windows.
[advt]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).
