A dead pixel is a point on a monitor that has failed completely and stays permanently black. This differs from a stuck pixel, which stays fixed on one color but still receives power, and can sometimes be fixed, while true dead pixels generally cannot.
- A dead pixel stays permanently black; a stuck pixel shows a fixed color.
- Stuck pixels can sometimes be fixed with gentle pressure or pixel-cycling software.
- True dead pixels are generally permanent and not fixable through software.
- Most manufacturers have a dead pixel policy determining warranty replacement eligibility.
Dead Pixel vs Stuck Pixel
A dead pixel has completely failed and shows no color at all, appearing as a persistent black dot. A stuck pixel is still receiving power but stuck displaying one specific color, commonly red, green, or blue, rather than the base black recommended state. This distinction matters because stuck pixels are sometimes fixable, while dead pixels generally are not.
How to Identify Which You Have
- Display a solid black background across the full screen; a dead pixel remains black (invisible against black), while a stuck pixel shows its fixed color even against black.
- Display solid white, red, green, and blue backgrounds in sequence; a stuck pixel will show its fixed color against most backgrounds, while a dead pixel remains black against all of them.
Fixing a Stuck Pixel
- Gently massage the specific pixel area with a soft cloth while the screen is off, then check if it resolved
- Use pixel-fixing software that rapidly cycles colors at that specific location, sometimes unsticking the pixel over several minutes
- Try gently tapping (not pressing hard) directly on the stuck pixel location while the monitor displays a black screen
Can Dead Pixels Be Fixed?
Generally no. A true dead pixel has failed at the hardware level and doesn’t respond to the pressure or software techniques that sometimes help stuck pixels, since there’s no remaining electrical function to manipulate.
Checking Your Manufacturer’s Dead Pixel Policy
Most monitor manufacturers have a specific dead pixel policy defining how many dead or stuck pixels, and in which screen zones, qualify for a warranty replacement. Check your specific manufacturer’s policy before assuming a single dead pixel automatically qualifies for replacement, since policies vary considerably.
Should You Return a Monitor With a Dead Pixel?
If discovered shortly after purchase and within your manufacturer’s or retailer’s return window, returning or exchanging the monitor is generally the most straightforward solution, rather than attempting fixes on a device you could simply replace.
Preventing Future Dead Pixels
Dead pixels are largely a manufacturing defect or random hardware failure rather than something caused by normal use, so there’s limited practical prevention beyond choosing monitors from manufacturers with generous dead pixel warranty policies.
Practical tip: thoroughly check a new monitor for dead or stuck pixels within the first few days of ownership, using the black/white/color background test, while you’re still within your return window.

Frequently Asked Questions
What’s the difference between a dead pixel and a stuck pixel?
A dead pixel stays permanently black with no power; a stuck pixel shows a fixed color while still technically receiving power.
Can I fix a dead pixel myself?
Generally no, true dead pixels are permanent. Stuck pixels, however, can sometimes be fixed with gentle pressure or pixel-cycling software.
Will my monitor’s warranty cover a dead pixel?
Depends on the manufacturer’s specific dead pixel policy, which defines how many affected pixels and in which zones qualify for replacement.
Should I return a monitor for one dead pixel?
If within your return window, yes, since returning or exchanging is generally more practical than attempting an unreliable fix.
