Stuck Pixel vs Dead Pixel: How to Tell

Understanding Pixel Defects

Modern displays are made of millions of tiny pixels, each with red, green, and blue subpixels. Sometimes a pixel doesn’t behave correctly, leading to a visible dot on your screen. Knowing the type of defect helps you decide whether it’s a temporary issue or a permanent one.

What Is a Stuck Pixel?

A stuck pixel is one that remains lit in a single color—red, green, blue, or a combination—regardless of what’s on the screen. It happens when the transistor controlling that pixel gets stuck, so it always receives power. Stuck pixels are often bright and can be distracting, but they are not always permanent. Some users report that gently massaging the area or using rapid color changes can help, but results vary.

What Is a Dead Pixel?

A dead pixel is one that appears black because it receives no power at all. This is usually caused by a broken connection or a manufacturing defect. Dead pixels are permanent and cannot be fixed with software or visual tools. They are most noticeable on white or light backgrounds.

Hot Pixels and Subpixel Defects

A hot pixel is similar to a stuck pixel but appears white or very bright because all three subpixels are stuck on. Subpixel defects occur when only one of the three color channels fails, causing a tiny dot that may be red, green, or blue. These are all variations of the same underlying issue: a pixel that doesn’t respond correctly.

How to Identify Pixel Defects

To spot defects, display solid colors that contrast with the pixel. For example, a fullscreen black screen will make stuck pixels (which are lit) stand out, while a fullscreen white screen will reveal dead pixels (which are black). You can also use red, green, and blue screens to isolate subpixel issues.

  1. Open a fullscreen black screen and look for any colored dots.
  2. Switch to a fullscreen white screen and look for black dots.
  3. Test red, green, and blue screens to see if the dot changes color.
  4. Note the location and color of each defect.

Can You Fix a Stuck or Dead Pixel?

There is no guaranteed software fix. Some people try pixel-flashing videos or gentle pressure, but these are not reliable and can sometimes make things worse. Dead pixels are permanent. Stuck pixels may occasionally resolve on their own. If your display is under warranty, contact the manufacturer for a replacement. Remember, using a browser-based tool like Black Screen cannot repair hardware—it only helps you identify the issue visually.
