Dead pixels are not the same as stuck pixels.
These pixels look almost the same, but there’s an important distinction.
A dead pixel won’t turn on, whereas a stuck pixel is permanently on.
If a problematic pixel is dead, it should look like a small black rectangle.
It may go away on its own, but there’s no telling how long it will take.
This free web app fixes many stuck pixels in less than 10 minutes.
There’s no software to download or install, and it’s suitable for LCD and OLED screens.
The most reliable way to fix a dead pixel is to replace the screen.
Most display manufacturers require a minimum number of dead pixels before the screen can be replaced.
For a display the size of acomputer monitor, the minimum is typically four to eight dead pixels.
Smaller displays have lower minimum requirements.
We do not recommend trying these methods as they can make the problem much worse if not done properly!
The most common cause of dead pixels is a manufacturing defect.
Undetectably small errors in assembly can result in a handful of dead pixels among the millions of functional ones.
But generally speaking, anywhere from one to five inactive pixels is considered okay according to industry standards.
