Frequently asked questions on dead pixels and stuck pixels

Are you unsure of what dead pixels are, look like? Do you have any further question on our dead pixel fixer? You'll find your answers below.

What is a dead pixel?

First, to understand what a dead pixel is, you need to understand what a pixel. Your screen, whether it is a desktop, laptop, a TV, a smartphone, is made of tiny sub parts that are called pixels. Pixels light up and change color individually according to the image that your screen needs to display. Sometimes, it appears that some pixels can be malfunctioning. A dead pixel is a black dot on your screen: the pixel cannot turn on and change colors anymore. Check out our article on what a dead pixel is for more information.

What are bad pixels and stuck pixels?

Sometimes, the malfunctioning pixels will not appear as black dots but can be stuck on any color. This is what we call bad pixels or stuck pixels. They are malfunctioning but are still “working” and showing signs of life. Therefore, your chances of repairing them are higher than if you had dead pixels. In any doubt, check our article on the difference between dead pixels and stuck pixels.

The short answer is “it depends”. There is a slight confusion on the internet on what dead pixels really are. By dead pixel, we mean a pixel that remains black whatever is being displayed on your screen. It is unlikely that you'll be able to repair it because the electrode that makes it change color seems dead. A stuck pixel or a bad pixel is generally stuck on one single color. In that case, the pixel is malfunctioning: it still works but not properly. There are several things you can try, starting with our dead pixel fixer.

How long does it take to fix a dead pixel?

The short answer is also “it depends”. Some stuck pixels will reactivate withing a fraction of a second after using our dead or stuck pixel fixing app, others will take minutes, other hours… Some of your pixels might not even be fixable at all.

Fixing a dead pixel manually: is it possible?
