Sometimes, a stuck pixel becomes unstuck on its own. This is a reversible process and can be fixed by several methods. There is a difference between a stuck pixel and a dead pixel.Ī stuck pixel, as mentioned earlier is stuck in a single color. Difference between a Stuck pixel and a Dead pixel When the pixel does not change color as it should, you will see it as an annoying spot on the screen.
It is usually caused when the transistor does not get enough power to change colors.Ī stuck pixel will then be stuck in red, blue or green and will not change color when you change the display. What is a stuck pixel and how does it get stuck?Ī pixel gets stuck when there is a faulty sub-pixel that is always on. We have outlined a few methods of solving the stuck pixel problem on your LCD screen. These colors combine to give you the final color on the screen. Each pixel on your monitor is made up of three separate sub-pixels in three colors of red, green and blue.
