Have a Dead Pixel on Your TV or Monitor? Here’s What That Means

One tiny pixel on your screen remains black. Unfortunately, that usually means it’s broken, but is it fixable?

So you’ve just noticed that your monitor has a little black dot on it even when it’s turned on. Someone says that it’s a dead pixel, but what exactly does that mean, and why has it happened? First, we’ll explain exactly what a dead pixel is, so you know how to avoid them in the future.

What Is a Dead Pixel?

A dead pixel is a name for a mechanical fault that can develop on TVs and monitors. For example, if you notice a small black dot on your TV or monitor screen, then you’ve found a dead pixel. This happens because power is no longer going to that pixel in question. As power is required for a pixel to show colors (even white), that pixel displays as black like it does when your display isn’t powered on at all.

What Causes Dead Pixels?

A dead pixel on a brand-new display is a sign of manufacturer fault most of the time. In most cases, you can avoid these kinds of dead pixels by ensuring you’re buying a screen from a trusted brand. Cheap, low-quality displays are much more likely to have a dead pixel problem from the factory.

If your screen develops a dead pixel well after you bought it, it’s likely because of physical damage to the screen. If a display is hit or knocked, it can cause something to break internally that stops power from getting to a certain part of your screen. A good way to avoid dead pixels is to ensure that you’re always careful around your electronics and don’t accidentally hit the screen.
