Have you ever encountered defects in the form of small dots on a camera/computer’s LCD monitor or screen smartphone/tablet? If your answer is “yes”, you probably know how irritating this problem is and reduce your productivity, especially when working with photos. Discover the proven methods to fix dead pixels and stuck pixels on your screens, enhancing clarity and productivity.

As practice shows, it is the stuck pixel vs dead pixel that often appear in gadgets. However, there is good news. You can fix these defects! But first, you need to learn to distinguish between two of these issues and find out the root of them to find the right solution. Let's talk about that in our article! 

What is a Stuck Pixel and How to Spot it?

Distinguish Between Stuck Pixel and Dead PixelFirst, let’s find out what is a pixel. This is a small object, usually rectangular, that contains three subpixels. They are painted in red, green, and blue colors. It’s pixels that make up full-fledged pictures, photos, and videos on smartphones, tablets, and laptop screens. But over time when actively using the gadget, there is a common occurrence, a stuck pixel. 

What does a stuck pixel look like? It appears as a dot in the same place and has one particular color: red, green, or blue. There can also be a combination of these colors. This dot typically doesn’t move, but can sometimes flicker. 

Why do they appear and how to fix stuck pixels on a phone or another gadget? The matter is that they always receive power. And when it receives incomplete information, it becomes defective, i.e., is displayed in only one of three colors. 


What is a Dead Pixel and How to Spot it? 

Fix Stuck Pixel on Monitor

A dead pixel is a pixel on a digital display that remains unlit, often appearing as a tiny black or white spot, due to a failure to receive power. Unlike stuck pixels which may display colors incorrectly, a dead pixel is completely inactive and does not display any color or light.

Difference Between Stuck and Dead Pixel: What Pay Attention to

Fix Dead Pixel on MonitorAt first glare, it may seem that stuck and dead pixels are almost the same thing. But, in fact, they are quite different. Below, we’ll explain why exactly:

  • Appearance and color. A stuck pixel appears as a single dot of a consistent color (green, red, or blue) or sometimes as a cluster of dots. In contrast, a dead pixel is either white or black and has a rectangular shape.
  • Rare or common phenomenon. The stuck pixel is a quite common problem that most often occurs among old monitors and those that you have not used for a long time. Can dead pixels spread regularly? They rarely appear on sensors and digital liquid crystal cameras. 
  • Possibility of fixing. The advantage of the stuck pixels is that they might disappear over time by themselves and are easily fixed. The dead are never fixed. But you can revive them. 

How to Test if there are Stuck vs Dead Pixels on New Screens with Special Checker Tools?

Stuck Pixel ColorSometimes it’s very difficult to detect the presence of dead or stuck pixels on new screens. But there are several ways, that will help you with this. If you suspect that your camera has defected with pixels, you can carry out testing right here. There are two effective methods: 

  • Test on camera LCD. Set Program/Auto or Aperture Priority mode, then turn on Live View. After these settings, point the camera lens at something bright. It could be the sky or green grass. Move the camera to the right, left, up, or down. If you’ll notice a small dot in the same place, the defective pixel is in front of you. You already know what colors are dead pixels. So, it wouldn't be difficult for you to determine exactly what the problem is in front of you. 
  • Test the camera sensor. First, set ISO 100 or 200, then take several photos with different colors and patterns. Carefully view them on your computer at 100% view size. Do you see how one pixel that stands out from the others appears in the same place? This is a defect we speak about. 

You also can test your screen for defective pixels more carefully using special programs or tools. Below we consider some of them.

    Main Reasons Appearing These Pixels Defects 

    Stuck Pixel ToolYou’ve found out what do dead pixels look like and what is the difference between them. So, let’s consider, why these defects appear. There are many reasons. But we will tell about the most common among them:

    • Overheating or overcooling. When you use your gadget near a hot battery or vice versa in a cold room or even on the street when frosty, it leads to the solidification of pixels and their immobility in the middle of liquid crystals. 

    • Transistor failure. As practice shows, this occurs after voltage drops, resulting in a particular pixel doesn’t receive energy and becoming dead. Also, the transistor becomes damaged and thereby leads to defects due to static showing the same picture for a long time by the monitor.

    • Overclocking. If you overclock your monitor, be prepared for such a phenomenon as excess heat, which leads to the appearance of shuck pixels. 

    • High Humidity. LCD monitors don’t like such conditions, because the matrix suffers and white dots appear. 

    So, how to fix stuck and dead pixels on phones or other gadgets on their own? After all, you don’t want to take your tool for repair and spend a lot of money on it. Let’s find out!

    How to Fix Dead Pixels on Android Phones and Other Gadgets Solely?

    Dead Pixel ToolIt is easy to fix stuck pixels because it’s a temporary problem. But you’ll have to tinker a bit with dead pixels. We suggest you familiarize yourself with several methods of fixing the defects that have already proven their effectiveness in the practice.

    1. Give your laptop, smartphone, or tablet a rest for 24 hours

    Sometimes, the issue appears, when you excessively use the gadget. In this case, you can try the safest option, which is suitable if you noticed stuck pixels. Just turn off the monitor and unplug it. Leave it in this condition for 24 hours. There is the possibility that after some rest, the issue will disappear by itself. But it could be later. It’s not really known how long it will take: a week, a month, or even a few years. 

    2. Use dead vs stuck pixel-fixing software

    Programmers, realizing how annoying such defects are, have developed special software that can effectively solve them. All variants of such tools work on the same principle. The software aims to return the pixel to its usual state by reproducing a chaotic combination of red, green, and blue colors. It happens cyclically at a rate of 60 flashes per second. But kip in mind one important thing. If you suffer from epileptic seizures, this method isn’t for you because of the rapidly flashing lights in an erratic pattern. 

    Here are three of the most common pixel-fixing software: 

    1. JScreenFix Online Tool

    Dead Pixel Color

    This free app helps you to solve the problem of stuck or dead pixels on a phone, laptop, tablet, or TV screen in 10 minutes.

    2. Locate the Defective Pixel. By switching to full-screen mode by pressing the green button, carefully look at the dark background and find the dead pixel vs stuck pixel.

    3. Position the Flashing Square. Drag the square of flashing pixels over the defective pixel.

    4. Wait for Result. Leave the flashing square on the problematic pixel for a duration ranging from 10 minutes to 1 hour. If the first attempt doesn’t resolve the issue, give your gadget a day’s rest and try again.

    Note: This app works only if the pixel is stuck. Do stuck pixels go away completely and forever? Not to the fullest extent. But it’s worth a try.

    2. UndeadPixel

    Pixel Test

    3. PixelHealer

    Pixel Repair Software

    1. Install & Launch. Download and open the PixelHealer app.

    2. Cover the Defect. The program provides a small colored window. Move this window to cover the defective pixel area.

    3. Start Flashing. Click the "Start Flashing" button. The program will begin flashing a series of colors (black, white, and main RGB colors) rapidly.

    4. Adjust Settings (Optional). Before starting the flashing, you have the option to set your preferred flashing interval and a timer to auto-close the application.

    Caution: Using this app, don’t look at the screen for a long time, because prolonged eye contact with blinking can lead to dizziness.

      3. Fixing Problem Manually 

      If you’ve tried all of the above methods and the problem remained unchanged, use one last chance to fix pixels by yourselves. This is a direct impact on them with your hand. In some cases, this method of “treatment” really works. Just follow the next steps:

      1. First, find out where is the defective pixel and turn off the monitor. 

      2. Press on the pixel. Wrap your index finger with a piece of microfiber and press where the stuck or dead pixel is located, while turning on the monitor. But do it very delicately so as not to damage your screen. Don’t press on other places, as this may lead to even more issue dots. Hold the pixel with your finger for 10 minutes and then put it away. You also can use a pen cap, marker, the tip of a makeup brush, or another blunt narrow object instead of the finger. Warm is one more way to solve the defect. Put a hot washcloth in a hermetical bag and don’t press too hard to it on the defective area, but not more than a few seconds at a time.

      3. Look at the result. Do dead pixels go away? Yes! Congratulation! You have coped with the issue. 

        You can combine this option with any of the tools which we talked about.  But keep in mind that it’s somewhat risky. But why? The matter is that this method may cause permanent damage to the screen and void your warranty if it’s still valid.
