:hap2: for people interested in lcd's, handy utility.
This software is extremely easy to use. It displays homogeneous colors (black, white, the primary colors etc.) on the entire screen, so you can easily recognize any faulty pixels. Step through the colors with the arrow keys and check every part of the LCD screen carefully. The color of dead or faulty pixels will be different. It is a good practice to run this software before buying an LCD monitor, or during the pixel warranty period.
There is no setup, no dependencies, it can even be run directly from a floppy disk or pendrive. No spyware, no malware.
