A dead pixel is a picture element that stops lighting up, causing a persistent black dot on the screen. Since it’s permanently on, it typically appears as a bright, persistent dot on the screen, and is either red, green, blue, or white. If a problematic pixel is dead, it should look like a small black rectangle.
How can you tell if you have a dead pixel?
The Difference Between Stuck and Dead Pixels Stuck pixels are usually red, green, blue, or yellow. Dead pixels are black. No matter how much your screen changes, those pixels will remain fixed in one spot and won’t change their colour. Keep in mind that stuck pixels can also be black or very dark in colour.

Apply pressure to the area where the stuck pixel is. Try not to put pressure anywhere else, as this may trigger the creation of more stuck pixels. While applying pressure, turn on your computer and screen. Remove pressure and the stuck pixel should be gone.
Are dead pixels white or black?
Stuck pixels are different from dead pixels. A stuck pixel is a single color – red, green, or blue – all of the time. A dead pixel is black instead. While it’s often possible to “unstick” a stuck pixel, it’s much less likely that a dead pixel will be fixed.

It is possible to get more, and if you have one the likelihood of more coming increases, but the dead pixel itself isn’t contagious so to speak. There are some temporary fixes that may work, such as flashing colors or rubbing the pixel.

How do dead pixels happen?
Dead pixels are usually the result of a manufacturing defect. If a defect prevents a pixel from receiving power, the pixel will remain black at all times. Bumping into or knocking over a display device, for example, may damage the power connection to one or more of its pixels, in which case a dead pixel can occur.
How many dead pixels are acceptable?
HP will accept up to five total subpixel defects, but zero full-pixel defects. Dell’s fancier monitors can’t have any bright sub-pixels but up to six dark subpixels are acceptable, while their lower-end displays can have between three and six bright subpixel defects.
Is one dead pixel a big deal?
One dead pixel on a new machine or display is one too many. Get it replaced with one that isn’t defective. If they give you any crap ask someone at an Apple store to show you a desktop, display, or notebook on display with a dead pixel. They won’t find one.
