What does a bad pixel look like?

Since the pixel is permanently on, a stuck pixel will typically appear as a very bright, persistent dot on the screen, and is either red, green, blue, or white. If your problematic pixel is dead, it will look like a small black rectangle.

Similarly, you may ask, what does a stuck pixel look like?

A stuck pixel is a single color – red, green, or blue – all of the time. A dead pixel is black instead. While a dead pixel may simply be stuck at black, it's possible that the pixel isn't receiving power at all. A faulty pixel displaying the color white all of the time is known as a “hot pixel.”

Subsequently, question is, how do you know if a pixel is stuck or dead? If you're completely sure that the pixels on your screen aren't dust, you need to identify them. 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.
