Stuck Pixel vs Dead Pixel: How to Tell

Understanding Pixel Defects

If you notice a tiny dot on your screen, it's likely a pixel defect. But not all defects are the same. Knowing the difference helps you decide what to do next. Here's a clear breakdown of stuck, dead, hot, and subpixel issues.

What Is a Stuck Pixel?

A stuck pixel is a pixel that remains lit in one color—red, green, or blue—because it's receiving a constant electrical charge. It appears as a bright, colored dot that doesn't change. Stuck pixels are often temporary and can sometimes be fixed with software or gentle pressure.

What Is a Dead Pixel?

A dead pixel is a pixel that receives no power at all. It appears as a black dot and is usually permanent. Dead pixels are caused by a manufacturing defect or physical damage. They cannot be fixed by software.

Hot and Subpixel Defects

How to Identify the Type

Use a fullscreen solid color screen to test. Display red, green, blue, white, and black screens. Observe the dot:

  1. If the dot stays the same color on all screens, it's likely stuck.
  2. If the dot is black on all screens, it's dead.
  3. If the dot changes color, it may be a subpixel issue.

Can You Fix Them?

Stuck pixels sometimes respond to software tools that rapidly cycle colors. You can also try gentle pressure with a soft cloth, but be careful—too much pressure can cause more damage. Dead pixels are permanent and may be covered by warranty if there are enough of them. Remember, a browser tool like White Screen (whitescreen.lol) is purely visual—it cannot repair hardware. It only helps you identify the issue.

When to Seek Professional Help

If the defect is under warranty, contact the manufacturer. If not, a professional repair may be costly. In many cases, a single dead pixel is not noticeable during normal use.
