UDPixel

UDPixel (also known as UndeadPixel) is a free utility that helps to locate and restore "stuck" pixels on an LCD monitor. It should be said that these are not completely "dead" pixels - such pixels cannot be restored without professional repair. UDPixel, like other programs of this kind, can recover, so to speak, "stuck" pixels, that is, those that constantly glow in only one color (green, red, etc.). The essence of the program is that it makes stuck pixels perform rapid color changes. In this way, pixels can come alive, but there is no guarantee of success. You need to start the program and, by clicking on the buttons with different colors (red, lime, blue, white, black, yellow or a custom color), fill the screen and identify all the stuck pixels. Then you need to choose the interval at which the colors will change (i.e. the rate of flickering colors), the number of flashing windows and the size of the square in which the colors will change (two options are available: 1x1 and 5x5 pixels) and click Start. A box will appear on the screen that you need to move onto a stuck pixel. It may take several hours to revive the pixel, but this procedure does not interfere with further work on the computer, which is an undoubted advantage of UDPixel. The program was written by Samuel Larché and requires the .NET Framework 2.0; its latest version, 2.2, was released in 2007.

UDPixel efficiently aids in the restoration of "stuck" pixels on LCD monitors without hindering computer usage.
