In this pixel-perfect journey, we’re unraveling the secrets behind those stubborn screen glitches, from what causes them to how you can kick them to the curb.

It is common for gadgets to have stuck or dead pixels, but the good news is that these defects are fixable. However, it is important to first distinguish between the two issues and determine the root cause in order to implement the correct solution. So, let’s discuss how to differentiate between stuck and dead pixels and how to resolve these problems.

Let’s crack the code!

An Overview of Dead Pixels

Before we dive in, let’s understand what a pixel is!

A pixel is a tiny, typically rectangular object consisting of three subpixels – red, green, and blue. These pixels are responsible for creating complete images, photos, and videos on various devices such as smartphones, tablets, and laptop screens.

Modern display devices such as computer monitors, televisions, smartphone screens, and human-machine interface (HMI) screens are made up of numerous individual pixels. Indeed, depending on the display device type, hundreds of thousands or even millions of pixels may be present. These pixels function by changing color in response to the image being displayed.

However, with prolonged use of electronic gadgets, stuck pixels can often occur, causing inconvenience to the users. Yes, there are instances when a pixel can stop functioning, resulting in a dead pixel.

Understanding of Dead Pixels

A dead pixel is when a pixel on a screen doesn’t do what it’s supposed to – change color. Typically, pixels are meant to show different colors to create the images you see on your screen. But a dead pixel just stays black all the time, no matter what’s on the screen. So, you can easily notice them by showing a white or bright picture on your screen – the dead pixel will stand out because it stays black while the rest of the pixels change colors.

Dead vs. Stuck Pixel: The Difference!

It’s essential to differentiate between stuck pixels and dead pixels, as they require different approaches to fix.

Stuck Pixels: A stuck pixel is like a pixel that’s stuck in one color mode – it could be red, green, blue, or a combination of these colors. Stuck pixels usually appear as a tiny dot that remains in one place, although occasionally they may flicker. The key point here is that stuck pixels still receive power and can often be revived.

Dead Pixels: On the other hand, dead pixels are essentially pixels that don’t receive any power at all. They are permanently off and typically appear as a small black or white rectangle on your screen. Dead pixels cannot be revived.

Now You’re in the Know About Dead Pixels, let’s know…

What Causes Dead Pixels?

Dead pixels are those annoying little spots on your screen that refuse to display any color, appearing as dead, black dots.

-Understanding why they occur can help you prevent and address this issue. Often, dead pixels that seem right out of the box are due to manufacturing defects.

-Choosing reputable brands when buying a screen can reduce the risk of encountering such issues, as cheaper, low-quality displays are more prone to these problems.

-However, if a dead pixel surfaces long after your purchase, it’s usually the result of physical damage to the screen, such as accidental impacts.

But what exactly causes these pixels to go “dead”? The culprit is often a disrupted power connection. Pixels need power to change color, and when this connection is severed, they become unresponsive and appear as black dots.

Several Factors Can Lead To These Power Disruptions:

Temperature Extremes: Using your device in extremely hot or cold conditions can cause the liquid crystals in the screen to solidify, trapping pixels in a fixed state.

Transistor Issues: Voltage fluctuations and prolonged display of static images can damage the transistors responsible for pixel control.

Overclocking: Pushing your monitor’s performance beyond its limits can generate excess heat, potentially harming pixels.

High Humidity: LCD monitors don’t fare well in high humidity, as it can lead to screen matrix deterioration and the emergence of white dots on the display.

To avoid dead pixels, handle your electronics carefully, protect your screen from physical damage, and be mindful of environmental factors like temperature and humidity.

Testing for Dead Pixels

Before attempting any fixes, it’s crucial to confirm if you indeed have dead pixels. Here are some methods to test for dead pixels:

Dead Pixels Test Websites

There are online websites that can help you identify dead pixels. These websites often display a single-colored screen, allowing you to spot any irregularities. If you see small black or white dots, those are likely dead pixels. The reliable websites you can use are;

Eizo Monitor Test:

This tool not only checks for dead pixels but also evaluates other aspects of your monitor’s performance. It provides a comprehensive assessment of your screen and can even attempt to fix stuck pixels.

Online Monitor Test:

This tool offers different modes to thoroughly test your screen, including red, blue, green, white, and black screens. If you observe anything other than the expected solid color, you might have dead pixels.

What Does A Dead Pixel Look Like On a Monitor?

Have you ever wondered what a dead pixel looks like on a monitor? Dead pixels appear as black and flat areas on your screen. However, before trying any fix, make sure your monitor screen is clean. Avoid rubbing your screen too hard, as it may worsen the problem and cause damage. So be careful while cleaning your screen to ensure it stays in good condition.

Methods to Fix Dead Pixels

Now that you’ve confirmed the presence of dead pixels on your screen, let’s explore some ways to address this issue:

1.    Give it a Rest

If you suspect your screen has stuck pixels, turning it off and unplugging it for 24 hours can sometimes help. Occasionally, stuck pixels may fix themselves over time.

Sometimes, overusing these devices can cause problems like stuck pixels. To address this issue safely, turn off the screen and disconnect it from power. Let it rest for a day. It may take some time, perhaps a week, a month, or even a few years, but this break could help the problem resolve itself naturally.

2. Use Dead Pixel-Fixing Software

Thanks to programmers, they have developed specialized software to fix annoying screen defects like stuck or dead pixels. These tools all work on the same principle, attempting to revive the problematic pixel by cycling through chaotic combinations of red, green, and blue colors at 60 flashes per second.

Important note:

It’s crucial to note that these rapid, erratic light flashes can trigger epileptic seizures, so it’s not recommended for individuals with such conditions.

Here are Three Standard Pixel-Fixing Tools:

  • JScreenFix Online Tool: This free application is suitable for phones, laptops, tablets, and TVs. It involves displaying flashing pixels on a black screen for 10 minutes to 1 hour to potentially revive stuck pixels.
  • UndeadPixel: A Windows program that locates dead pixels and provides a blinking dot to place over them. You need to leave it for 2 hours for the program to work its magic.
  • PixelHealer: This free app is compatible with various devices. It employs a “shock therapy” approach by rapidly flashing black, white, and RGB colors over the affected area.

Be cautious! Do not stare at the screen for too long to avoid dizziness. These methods may not eliminate stuck or dead pixels, but they are worth a try.

3. Manual Intervention

This method involves applying gentle pressure to the dead pixel using a soft cloth-covered finger or a blunt object like a pen cap. While this technique can sometimes work, it carries the risk of damaging the screen further, so proceed with caution and handle it with care!

And what if none of the fixes work?

In all honesty, sometimes none of the methods may prove effective, and the dead pixel remains stubbornly persistent. If this happens and your device is still under warranty, consider reaching out to the manufacturer or taking it to a service center for a screen replacement. Keep in mind that warranty policies vary, and they usually cover a specific number of dead or bright pixels.

The Verdict

Well, now you know how to fix Dead Pixels. Glee! Dead pixels may be a nuisance, but they are not invincible. Whether it’s through software solutions, manual intervention, or simply giving your device a break, there’s a good chance you can bid those bothersome dead pixels farewell. So, fear not, pixel predicaments can be resolved, and your screen can shine brightly once more!
