Dead Pixel Tester - 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 off (resulting in a "dark" defect). DPT was written to help me check my own screens 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 noticed then pixels that are not on due to their size (normally under .5mm).

Usage:
Left mouse click : Quick colour selector
Middle mouse click : Moves to next colour (Cycle is White/Black/Red/Blue/Green)
Right mouse click : Closes application

This is a nifty little (only 163 Kb) program. Just download using the link at the top of this post. There is no installation required. After downloading the file, just double-click on it to run it. Then click the middle mouse button to cycle through the primary colors used by the pixels of your LCD monitor.

This is an awfully OLD thread!

But the program seems to still work.

When I bought this new LCD monitor a couple of months ago, it had several stuck pixels. I massaged them with a finger tip and they seem to have gone away.

The pixel tester found nothing.

thanks,
