Fix a Stuck Pixel: All the Methods to Revive Bad Pixels

Stuck pixels are a common annoyance, displaying a single color like red, green, or blue instead of changing with the rest of the screen. This guide will explain what causes stuck pixels, provide methods to attempt fixes, and offer tips to prevent future pixel issues.

What is a Stuck Pixel?

A stuck pixel is a single point on a display screen that continuously displays one color due to a sub-pixel malfunction. Unlike dead pixels, which appear as black or unlit spots, stuck pixels remain brightly lit in one color. This defect can occur due to minor electrical issues or manufacturing flaws, and it’s most common on LCD, OLED, and LED screens.

Stuck Pixels vs. Dead Pixels

Differentiating stuck pixels from dead pixels is fairly easy:

How to Identify a Stuck Pixel

If you suspect a stuck pixel, run a Dead Pixel Test on DeadPixelTest.org. Display solid colors like red, green, blue, and white to spot any pixels that remain unchanged across different backgrounds.

Is it Possible to Fix a Stuck Pixel?

While stuck pixels can be frustrating, the good news is that they are often fixable, especially compared to dead pixels, which are typically permanent. Stuck pixels are caused by sub-pixels getting stuck in the "on" position, and they often respond well to various techniques such as pixel-fixing software or gentle physical manipulation. Methods like flashing colors rapidly across the pixel or applying gentle pressure aim to stimulate the malfunctioning sub-pixels back into working order. However, success is not guaranteed, and sometimes multiple attempts are needed to see results. If a stuck pixel remains unresponsive, it may be time to consult professional repair services or consider a screen replacement, especially if the pixel is in a noticeable area. Generally, stuck pixels have a higher chance of recovery than dead pixels, making these methods worth trying before opting for replacement options.

Methods to Fix a Stuck Pixel

Fortunately, stuck pixels are often fixable using software tools, manual techniques, or a combination of both. Here are the most effective methods.

1. Pixel Fixer Software

Pixel-fixing software works by rapidly flashing colors on the screen, attempting to stimulate the stuck pixel back to normal:

  1. Visit Dead Pixel Fixer on DeadPixelTest.org.
  2. Play the pixel fixer video or use the web-based tool, which cycles through colors at high speeds to stimulate the pixel.
  3. Let the software run for 10–30 minutes and check the screen to see if the stuck pixel has returned to normal.

This method is especially effective on screens where the issue is caused by a minor sub-pixel malfunction.

2. Gentle Pressure Method

The gentle pressure technique is a hands-on way to potentially reset a stuck pixel. Here’s how to perform it safely:

  1. Turn off your screen and prepare a soft cloth, such as a microfiber cloth.
  2. Locate the stuck pixel, place the cloth over it, and apply gentle pressure using a blunt, rounded object (e.g., the eraser end of a pencil).
  3. Hold the pressure for 5–10 seconds, then remove it and turn on your screen to check the pixel.

Note: Excessive pressure can damage your screen, so apply very light pressure only. This technique can sometimes help unstick the malfunctioning sub-pixel.

3. Warm Cloth and Gentle Massage

For a slightly different approach, a warm cloth and gentle massaging motion can help stimulate the pixel.

  1. Turn off your device and heat a microfiber cloth until it’s slightly warm (do not use a very hot cloth, as this could damage the screen).
  2. Place the warm cloth on the stuck pixel and use light, circular motions to massage the area for 5–10 seconds.
  3. Turn on the screen and see if the stuck pixel has been restored.

This technique combines warmth and gentle motion, which may help reset minor electrical issues causing the stuck pixel.

4. Cycle Screen Brightness

Another approach involves repeatedly adjusting the brightness to stimulate the pixel. Follow these steps:

  1. Dim your screen brightness to the lowest setting and then gradually increase it to the highest setting.
  2. Repeat this cycle several times.
  3. Inspect the screen to see if the stuck pixel has reset.

This method is safe for all screens and might work on pixels that respond to slight electrical changes.

5. Use a Third-Party App

There are many apps available for mobile and desktop devices that flash colors to stimulate stuck pixels. Some of the most popular include:

Run the app near the location of the stuck pixel, allowing it to run for 10–20 minutes. Apps like JScreenFix can provide an easy, no-download solution.

When to Seek Professional Help

If none of these methods revive the stuck pixel, it might be time to consider professional repair:

Keep in mind that some screens, especially OLED displays, may be more susceptible to permanent pixel issues, so consider these methods carefully.

Tips to Prevent Stuck Pixels

While not all stuck pixels are preventable, these best practices can help reduce the likelihood of encountering them:
