Dead Pixel Locator is a handy and reliable utility designed to help you check the LCD monitor or plasma display for dead pixels.

Still, every manufacturer has a dead pixel policy, which you should read carefully. If you find any defective pixels on your new LCD monitor or plasma display during the warranty period, it may qualify for a replacement.

There are 3.9 million sub-pixels (red, green and blue) on a standard 1280×1024 resolution LCD monitor, and each of these is a microscopic transistor.

While the defective rate of pixels on LCD panels and plasma displays is very low, due to the large number of sub-pixels, manufacturers cannot guarantee 100% error-free panels at an affordable price.
