DeadPix Portable is a lightweight application designed to identify and quickly fix dead pixels on your screen by cycling through multiple colours. There are two main components that make up DeadPix Portable: the pixel locator and the fixer. You can choose the colour that will cover the entire screen in order to spot the dead pixels. The typical options include red, green, blue and black, but you can look for a custom colour in the options provided by the program as well as use a random mode to toggle multiple colours.
