Bad Crystal - a utility for the identification and treatment of broken pixels, as well as to eliminate dark areas on the monitor, left after static objects. It must be said that the dead pixels can’be’completely restored without professional repairs. Bad Crystal, like other programs of this kind, can restore, so to speak, "sticky pixels", that is, those that glow constantly only one color (green, red, etc.). The essence of the method of treatment of broken pixels is the forced change of colors at high speed in the area of the monitor where the broken pixel is located. With this load, a pixel can come alive.
If you select the corresponding option, a window will appear, inside which the colors will change in a chaotic order. It's a window to point at the pixel that hangs in the air, waiting for it to come to life. However, it's hard to say exactly how long you'll have to wait. This procedure can last from a few minutes to several hours and even a day. And there's no guarantee that the pixels will come alive at all.
Bad Crystal software's main benefit is that it potentially repairs broken pixels and reduces dark monitor areas, enhancing display clarity and quality.
Important note: during the pixel recovery operation, the window with the changing colors is always at the top of other windows, which allows you to continue your work unhindered.
