Fix Stuck & Dead Pixels

Diagnosis and repair methods for display defects.

Stuck vs. Dead Pixels: What’s the Difference?

Before attempting a fix, it's crucial to identify the type of defect you're dealing with.

  • Stuck Pixel: A pixel that is permanently "on," displaying a specific color (usually red, green, or blue). These are often fixable because the liquid crystal is just stuck in one position.
  • Dead Pixel: A pixel that is permanently "off," appearing as a tiny black dot. This indicates the transistor powering the pixel has failed. Dead pixels are rarely fixable.

Use our Monitor Test Tool to cycle through solid colors (Red, Green, Blue, White, Black). This makes it easy to spot any anomalies.

Method 1: JScreenFix (Pixel Flashing)

The most common software fix involves rapidly flashing colors over the stuck pixel. This rapid change in voltage can sometimes unstick the liquid crystal.

  • JScreenFix is a popular web-based tool for this.
  • Alternatively, use a flashing video on YouTube.
  • Note: You may need to run this for anywhere from 10 minutes to several hours.

Method 2: The Pressure Method

If software fails, you can try physically massaging the pixel back to life. Use extreme caution to avoid damaging the screen further.

  1. Turn off your monitor.
  2. Get a damp cloth (so you don't scratch the screen).
  3. Apply gentle pressure directly on the stuck pixel with a blunt object (like a pen cap wrapped in the cloth) or your fingertip.
  4. While holding the pressure, turn the monitor back on.
  5. Release the pressure. The pixel might start working again.

Method 3: Heat Method (Risky)

Some users report success using heat. Soak a cloth in hot water (not boiling), wring it out, and place it (inside a protective plastic bag) against the stuck pixel for a few minutes. The heat can sometimes help the liquid crystal flow better.

When to Return Your Monitor

Manufacturers have specific policies regarding dead pixels (ISO 13406-2). Most "Class II" monitors allow for a small number of dead pixels before they are considered defective. Check your warranty policy—sometimes even 3-5 dead pixels are considered "within spec."
