Faulty pixels in the display
At present, the manufacturing process of modern displays does not guarantee that all pixels
of the display will be perfect. A small number of faulty pixels in the display, is therefore
unavoidable. This does not present a functional problem as long as the faulty pixels are not
bunched in one location.
For additional information, refer to the specifications.
