Pixel Check

A dead pixel, or Dead Pixel/Defective Pixel, are pixels on a liquid crystal display that are not working as expected. The ISO 13406-2 standard distinguishes between three different types of defective pixels, while hardware companies tend to have other types of distinctions.

The function of Pixel Check is only to help in the search for dead pixels on the screen. When displaying the RGB primary colors, it is possible to check whether any deformity occurs between the pixels that make up the screen.
