Dead Pixel
A permanently failed pixel showing as a fixed dot on screen. Usually cosmetic — but spreading clusters after a drop signal a cracking panel that needs replacement.
A dead pixel is a pixel that has permanently stopped working. It appears as a fixed dot — usually black, white, red, green, or blue — that remains the same colour regardless of what’s on screen.
A single failed pixel is nearly invisible in normal use. Most people don’t notice one unless they’re specifically looking for it.
| Type | Appearance | Fixable? |
|---|---|---|
| Dead pixel | Always black | No — panel replacement only |
| Stuck pixel | Fixed colour (red/green/blue) | Sometimes — pixel-fixing tools |
| Hot pixel | Always white/bright | Rarely |
Single isolated pixel: Almost always cosmetic. Normal wear or a manufacturing defect.
Cluster after a drop: Red flag. Pixel clusters after impact indicate internal LCD cracking — the crack will spread. Get the panel replaced before it worsens.
Growing cluster over time: The panel is failing. Replace it before the entire display becomes unusable.
Can dead pixels be fixed without replacing the screen?
True dead pixels (always black) cannot be fixed without panel replacement. Stuck pixels (fixed colour) can sometimes be resolved with pixel-exercising software.
Do dead pixels spread?
A single manufacturing-defect dead pixel is stable. Dead pixels after physical impact indicate internal LCD cracking, which will spread.
Is one dead pixel a reason to replace the screen?
For a single isolated stable pixel, most users don’t bother. If it appeared after impact and is growing, replacement makes more sense.
