Dead Pixels are a common problem that LCD screens face. When a pixel goes dead, the LCD monitor does not display the correct color output.
Pixel Doctor is a handy utility that will enable you to easily repair the dead pixels on your LCD screen.
To fix a dead pixel, select a color and the Start Single Test. If you see any dead pixel/ss on your LCD screen, run the Start Therapy tests, either through Full Screen Method or Location Method.

InjuredPixels is another such tool which performs basically the same function. InjuredPixels allows you to easily check for dead or defective pixels on LCD monitors. InjuredPixels can be used to test a new LCD monitor before purchasing, or an already purchased monitor during the warranty period.
