Once the color is displayed you simply look over your monitor and determine if there are any parts of the screen that show a differing color. You then chose the color you want and it displays that color full screen. Just launch it and it will give you a choice of colors to display on the screen. If you think something about your monitor is off and you want to diagnose it yourself saving time and money from bringing your equipment into a shop this is the tool for you!
Run through the red, green and blue colours in turn and check for pixels that do not match.Dead Pixel Buddy is a great little program for determining if you have any dead pixels on a plasma or LCD screen. It simply paints your entire screen with one of the colours that make up a pixel to make the dead pixel more conspicuous to the naked eye. If you need to absolutely make sure whether you have purchased a defective display, you can use this program. Because of the complexity of the design, it is generally regarded dead pixels appearing in some products are inevitable. If you´ve scoured every inch of your screen but can´t find a single dead pixel, you are in luck. Or a slight bump during shipping can break one of the highly sensitive pixels. Even a tiny dust particle on one of the pixels during the manufacturing process can create a dead pixel. A typical 17 inch monitor contains up to 4 million pixels. It may look like a tiny black spot on your screen, or any other colour that does not correspond to what the actual image should look like. A dead pixel refers to a pixel with a defect in its ability to display the correct colour output. A typical monitor has millions of pixels. Pixels consisting of these valves are what make up the image that is ultimately displayed on the screen.
By manipulating the amount of light passed through, each pixel displays a distinctive colour on screen. The valves in each colour either block or pass the light source. Each pixel is made up of red, blue and green valves. An LCD display is essentially made up of pixels. Before trying to grasp the meaning of a dead pixel, first you need to understand the technology behind LCD displays. This is a program for testing LCD screens for dead pixels.
