Dead Pixel Symptoms

What Is Your Screen Telling You? Dead Pixel Symptoms and Diagnosis Guide

When you buy a new device or use your current screen, you may notice some peculiarities. Those small dots, often mistaken for dust, may actually be a hardware distress call from your screen. Here are the clearest signs that there is a problem with your screen:

1. Stubborn Dots That Don't Change Color

• Stuck Pixel Symptom: If you see a constant red, green, or blue dot on your screen, this is a "stuck pixel".
• Dead Pixel Symptom: If the dot is completely black or bright white and frozen, that pixel is no longer receiving power.

2. Permanent Spots That Look Like "Dust"

This is where users are most often mistaken. Small black dots the size of a pinhead that do not go away despite cleaning the screen are the harbinger of a dead pixel.

3. Brightness Loss in Mobile Devices (Dead Pixel Phone Symptoms)

This symptom, which you can notice while doing a Dead Pixel Test Phone on your phone, is that the pixels in a certain area of the screen remain dimmer than others.

4. Horizontal or Vertical Line Formations

If you see thin colored lines running all the way across your screen, this is a sign of a serious panel failure.
