Dead Pixel Tester 2.50

Dead Pixel Tester helps you find and recover stuck or dead pixels on your LCD screen. The DPT tool might help, but it does not guarantee 100% recovery, so don’t get your hopes too high. TFT screens have thousands of pixels, on a 1024×768 monitor, there are three cells for each pixel – one each for red, green, and blue – which amounts to nearly 2.4 million cells (1024x768x 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). DPT was written to help checking multiple screens by cycling through the three primary colors used (red, green, blue) and all on (white) and all off (black). In most cases, a stuck or dead pixel is impossible to fix (some people rub them gently with a cloth etc. search the net for other ways), however most manufacturers have a policy which will specify that after X amount of dead/stuck pixels they will replace the screen free of charge (in warranty period). You can use DPT to help identify IF you have any pixels and how many in order to see if you qualify for a replacement screen/laptop… no guarantees though! There has been some talk on the web of a video that can cure stuck pixels on the PSP, which works by rapidly changing the colour of the pixels. That’s why DPT offers a similar way of tying to recover these pixels by its own pixel exerciser. This will bring up another moveable window, that you can put over the stuck pixel(s) which will randomly change the colour of the pixel. Different places say different things on the effectiveness of this, but most leave it running for several hours before they see a result. The speed of this and colours shown has been improved in version 2.50+ and you can now use [E] to start a new Exerciser.
