Dead Pixel tester

Dead Pixel Tester

Dead Pixel Checker Ver 2, shows different colours accross multiple monitors to allow you to check for dead and stuck pixels (manually!)

TFT 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 (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 me check my own screens (Couldn't find one that worked across multiple desktops so had to write my own!) by cycling through the three primary colours used (red,green,blue) and all on (white) and all off (black). Simply select a colour then closely inspect your monitor in each of the primary colours checking for pixels that are not operating as expected. Stuck pixels (always on) are easier to notice than pixels that are not on due to their size (normally under .5mm). This application is freely distributable for non commercial gain, for any other usage please contact us.




A utility to simplify the transfer to pictures from your digital camera/card reader to your pc.

Transferer is a small application that tries to help simplify the transfer of photos/images from your digital camera (or card reader) to your PC. I wrote this for my own usage as I became irritated at the same procedure to move photos from my digital camera to my PC.
