The visible result is afixed pixel that appears as an extremely tiny dark or bright discolored spot. When the pixel remains permanently lit, it is known as a "bright dot". Wh en thepixel remains black, it is known as a "dark dot".In almost every case, these fixed pixels are hard to see and do not detract from display quality or usability. A display with 1 to 5 fixed pixels is considerednormal and within competitive standards. For more information, see Dell Support site at: support.dell.com.
