Solved: How To Fix Dead Pixels On Laptop

A dead or stuck pixel on your computer screen can be extremely inconvenient. Here are the most effective methods for testing your screen and for repairing dead pixels.

It’s possible to fix that pesky dead or stuck pixel on your TFT, OLED, or LCD panel with relative ease. Remove yourself from staring at your screen, wondering how much time you’ll waste while sending your monitor in for repair or replacement. You’ve already squandered enough time worrying about something as insignificant as a “dead” pixel, but which is nonetheless quite unpleasant.

Take matters into your own hands and attempt to repair the broken pixel on your own! Performing this procedure with care will not void your warranty and may even save you a significant amount of time and aggravation.

So, let’s have a look at how you may repair dead pixels on your computer screen.

How to Test New Screens for Stuck or Dead Pixels

Yes, you should thoroughly inspect each new LCD, OLED, or TFT screen for dead or stuck pixels as soon as it arrives. Using a tool such as EIZO Monitor Test, you can simply run your monitor through a palette of basic colors, as well as black and white, in full-screen mode.

1. EIZO Monitor Test

EIZO Monitor Test is an online tool that allows you to identify and, finally, resolve blocked pixels on your computer monitor. It crams a lot of options into a little test window, but it’s simple to use once you get a handle on what’s going on.

To put your screen through its paces, check all of the boxes you want to include in the test. We recommend that you leave all of the boxes checked as the default configuration. In the event that you’re testing on more than one monitor, you can open the test on a second monitor as well. When you’re ready, click Start test to bring up the full-screen test window on your computer.

The first test pattern is shown in the image below. Each screen contains an explainer in the lower right corner that explains what you should look for on that particular screen. On the left-hand side of the screen, you’ll notice a menu that allows you to move from one test to the next. Examine our screen after passing through all of the black and white screens as well as all of the solid colors (green, blue, and red). To exit, press the ESC key on your keyboard or the exit symbol in the top right corner.
Using a tool like UDPixel or JScreenFix to flash a stuck pixel is recommended if you detect one on your screen.

2. Online Monitor Test

While this is an in-depth test, it is also powerful enough to determine the quality of your monitor’s pixels, in addition to identifying faulty pixels. Unfortunately, because Flash is no longer supported by the majority of browsers, you’ll almost certainly have to use the executable version in order for it to run properly.

In order to test your screen, you can pick between three distinct modes. When you run the executable, the following is what you should see on your screen:

After moving the mouse pointer to the very top of the test window, a menu will appear. With a button in the top right corner of the menu, you can turn off the information window that appears on the screen. Select the Homo Genuity test point and navigate through the three hues as well as black and white to determine its homogeneity.

Keep your fingers crossed that you won’t come across anything out of the norm. In the sad event that this occurs, let’s examine whether the pixel is stuck or dead, and what you may do to resolve the situation.

Is It a Stuck or Dead Pixel?

What does it matter if you happen to notice an unusual pixel? Is what you’re seeing simply a stopped pixel, or is it a dead pixel in its truest sense?

A stuck pixel will appear in any of the three hues that can be formed by its three sub-pixels, namely, red, green, and blue. A dead pixel is one in which all of the sub-pixels are permanently turned off, resulting in the pixel appearing completely black.

It’s possible that a faulty transistor is to blame. Even a black pixel, on the other hand, may become stuck in rare instances.

Consequently, if you’re experiencing a colored or white pixel, you might be able to resolve the issue. And if you see a black pixel, the chances of success are slim, but there is still a slim chance.

Let’s have a look at some of the approaches for resolving a stuck pixel.

How to Fix Dead or Stuck Pixels

A dead pixel, on the other hand, cannot be repaired. A trapped pixel, on the other hand, can be repaired. As previously said, it is difficult to distinguish between the two. In any case, the following are the approaches you can take:

• First, detect any dead or stuck pixels on your monitor by switching between different color palettes.
• If a pixel appears to be stuck or dead, use a third-party program to flash the pixel with numerous colors in order to fix it. We recommend UD Pixel (Windows) or LCD as a display option (online).
• The manual approach, which involves rubbing the stuck pixel with a moist cloth or an object with a pointed but soft tip, such as the rubber/eraser tip on the end of a pencil, is the final option.

Let’s take a closer look at each of these strategies and tools.

1. JScreenFix (Web)

When it comes to stuck pixels, J Screen Fix will not assist you in finding them; however, they can be fixed with its assistance. At the bottom of the page, click the Launch J Screen Fix button to begin the process.

It will open a black browser window with a square of flashing pixels in the top right corner of the browser window. If you want to view the video in full-screen mode, click on the green button at the bottom right. Dragging the flashing square to the location where the stuck pixel was discovered and leaving it there for at least 10 minutes will yield the best results.

2. UDPixel (Windows)

UD Pixel, often known as Undead Pixel, is a software application for the Windows operating system. It can assist you in identifying and correcting pixels using a single tool. The Microsoft.NET Framework is required in order to run the software. If you don’t have Windows or don’t want to install any software, you can use the online tools listed further down the page.

When you use the Dead pixel locator on the left, you can quickly and simply detect any screen abnormality that may have eluded your notice up until now.

If you notice a suspicious pixel, switch to the Undead pixel side of things, generate an appropriate number of flash windows (one for each stalled pixel), and press the Start button. You can move the tiny flashing windows to the locations where you discovered the unusual pixels.

Allow them to run for a period of time before adjusting the Flash frequency.

3. PixelHealer (Windows)

To complement its Injured Pixels tool, Aurelitec developed this Windows application to identify dead, stuck, or overheating pixels.

The Pixel Healer allows you to flash a mix of black, white, all basic colors, and a custom color in a draggable window that can be customized in both size and shape. You may even customize the flashing interval and set a timer to automatically terminate the app.
To exit the app, click the Close Pixel Healer button located in the bottom right corner of the screen.

4. Dead Pixel Test and Fix (Android)

Using this Android utility, you can both test and repair dead or stuck pixels on your Android phone or tablet.

Allow it to cycle through all of the colors in Auto mode to determine whether or not you have any strange pixels on your screen. If you do, you should initiate the fix, which will rapidly flash your entire screen with black, white, and basic color pixels to demonstrate its effectiveness.

5. Manually Fix Stuck Pixels

If none of these tools are successful in resolving your stuck or dead pixel issue, there is one more option. You can use any of the tools mentioned above in conjunction with the magical power of your own hands. On wikiHow, you can find a thorough description of all of the possible strategies. On Instruct Ables, you may find another another excellent step-by-step tutorial.

Let’s take one method at a time and go through it:

• Turn off your computer’s monitor.
• To avoid scratching the screen, use a moist towel to wipe it down once you finish.
• Apply pressure to the place where the pixel has become stuck. Avoid applying pressure to any other part of the screen, as this may result in the production of more stuck pixels.
• Turn on your computer and screen while putting pressure to the keyboard.
• Remove the pressure from the area, and the trapped pixel should disappear.

This works because the liquid in one or more of the sub-pixels of a stuck pixel has not distributed evenly throughout the entire pixel. When the backlight of your screen is activated, varying amounts of liquid run through each pixel, resulting in the appearance of distinct colors. When you apply pressure, you are forcing the liquid out, and when you remove pressure, there is a good probability that the liquid will push back in, spreading evenly across the container.

All Pixels Report to the Screen

If none of these ways succeed in restoring life to your dead pixel warrior, at the very least you’ll have learned that it’s not an easy problem to fix and that you may have to replace the screen entirely.
