Quote:With Dead Pixel Tester (DPT) you can test your LCD screen for dead pixels.
Portable, no installation required.
LCD screens have thousands of pixels, on a 1024x768 monitor, there are three cells for each pixel - one each for red, green, and blue - which amounts to nearly 2.4 million cells (1024x768 x 3 = 2'359'296). There's only a slim chance that all of these will be perfect; more likely, some will be stuck on (creating a "bright" defect) or dead (resulting in a "dark" defect). Dead Pixel Tester was written to help you check your screens by cycling through the three primary colors used (red, green, blue) and all on (white) and all off (black).
