A Stuck Pixel on Your Screen 5 Solutions


It might be irritating to have a dead or stuck pixel on your screen. Here are the top techniques for checking your screen and repairing dead pixels.

Your TFT, OLED, or LCD screen’s bothersome dead pixel may just be stuck and simple to fix. You’ll see how to accomplish it from us. If this doesn’t work, you may still return your monitor because nothing we suggest here will void your warranty.

Let’s look at several fixes for heated, dead, or stuck pixels on screens.

How to Check for Stuck or Dead Pixels on New Screens
Yes, you should check for defective pixels on any new display. Using a program like EIZO Monitor Test, you can quickly test your screen in full-screen mode with a range of primary colors and black and white.

 Part 1 EIZO Monitor Test,

You may locate blocked pixels using the web application EIZO Monitor Test and finally resolve them. It crams a lot of options into a little test window, but once you get a handle on everything, it’s simple to use.

Check all the boxes you wish to test on your screen before you start. The default configuration, with all items ticked, is what we advise. Open the test on a different monitor if you’re testing several displays. Click Start test to open the full-screen test window when you’re ready.

See the first test pattern down below. In the lower right corner of each screen is a description of what to look for. Next, you’ll notice a menu on the left that allows you to move from one exam to the next. Check our screen after moving through the screens in all the solid hues (green, blue, and red) and black and white. Press the ESC key or the exit icon in the upper right to leave.

This is a highly complete test that is strong enough to evaluate the caliber of your display in addition to identifying faulty pixels. Unfortunately, you will probably need to use the executable version to make Flash operate as most browsers no longer support it.

To test your screen, you may select one of three modes. What you should see when you execute the executable is as follows:

A menu will display when the mouse is moved to the top of the test window. A button in the upper right corner of the menu allows you to close the info window. Click the Homogenuity test point after that, and then toggle between the three hues and black and white.

I’m crossing my fingers that you won’t find anything unusual. Let’s examine if it’s a stuck or a dead pixel and what you can do to fix it in the sad event that you do.

Is the pixel active or inactive?

What if you see a strange pixel? Is what you observe indeed a dead pixel or just a trapped pixel?

Because it gets insufficient information, a stuck pixel, sometimes incorrectly called a hot pixel, is flawed. As a result, it shows up in one of the three colors—red, green, or blue—that can be created by its three sub-pixels. Hot pixels in digital cameras only really show when electrical charges get into the camera’s sensor wells. The trapped pixels can sometimes self-correct.

All of the sub-pixels of a dead pixel are always off, giving the pixel a black appearance. A faulty transistor may be the root of the problem. But sometimes, even a dark pixel could just be trapped.

Therefore, if you spot a colored or white pixel, you might be able to correct it. And while there is a little possibility if you see a dark pixel, there is yet hope.

Now let’s discuss how to unstick a pixel.

How to Resolve Stuck or Dead Pixels

A dead pixel can’t be fixed, regrettably. A trapped pixel can, however, be fixed. It’s challenging to distinguish between the two, as I said above. In any case, you might attempt the following techniques:

First, check your display in various color palettes to find any dead or stuck pixels.
Use a third-party tool to flash the pixel with a variety of colors to correct any stuck or dead-looking pixels. We advise LCD or UDPixel (Windows) (online).
As a last resort, you may attempt the manual approach, which entails rubbing the trapped pixel with a wet cloth or a sharp but gentle object like the eraser on the end of a pencil.
Let’s take a closer look at these techniques and resources.

JScreenFix 1. (Web)

You can use JScreenFix to repair stuck pixels even though it won’t help you discover them. Simply select Launch JScreenFix from the page’s bottom menu.

Overview and start buttons are available in JScreen Fix.
A square of flashing pixels will appear in a black browser window when the utility loads. To go full-screen, click the green button at the bottom right. Place the flashing square there for as least 10 minutes once you’ve located the trapped pixel.

Windows software called UDPixel is also referred to as UndeadPixel. Using a single tool may assist you in locating and repairing pixels. The Microsoft.NET Framework is necessary for the software. The web tools are below if you don’t use Windows or don’t want to install any software.

The Dead pixel detector on the left makes it simple to find any screen anomaly that may have escaped your attention up until this point.

If you see a suspicious pixel, move to the Undead pixel section, make enough flash windows (one for each stalled pixel), and then press Start. You can move the little flashing windows to the odd pixel locations.

After letting them run for a bit, adjust the Flash interval.

PixelHealer 3. (Windows)

This Windows application was created by Aurelitec as a complement to their InjuredPixels program to find heated, stuck, or dead pixels.

In a draggable window with adjustable size, the PixelHealer enables you to flash a mix of black, white, all primary colors, and custom colors. You may also set a timer to automatically end the app and modify the flashing interval.

Fix Stuck Pixels by Hand

If none of these tools can fix your stuck or dead pixel problem, there is still time. You can combine any of the tools mentioned above with your magical power. On wikiHow, every technique that is accessible is described in great detail. On Instructables, you may find another excellent step-by-step tutorial.

Let’s quickly go through one technique:

OFFSET your display.

  1. To prevent scratching the screen, get a wet towel.
  2. Press down on the spot where the trapped pixel is located. Avoid applying pressure elsewhere to prevent the formation of further stuck pixels.
  3. Your computer and screen should be turned on while exerting pressure.
  4. Once pressure is released, the trapped pixel should go.
  5. This operates because the liquid in one or more of the sub-pixels of a stuck pixel has not been distributed evenly.
  6. When the backlight of your screen comes on, various volumes of liquid travel through the pixel to produce various colors. Applying pressure forces the liquid out, and releasing pressure likely causes the liquid to push back in and distribute evenly as it should.

What Should You Do If Your Pixel Is Stuck or Dead?

The next best thing to do after doing everything to resuscitate your lousy pixel is to accept it. One undesirable pixel won’t ruin your screen, and you’ll soon stop thinking about it. However, if the flaw impacts many pixels or merely annoys you a lot, you can always get a new monitor.

Check the warranty first. Dead pixels may be covered by the manufacturer or the store where you bought the monitor. The warranty won’t kick in until your monitor exceeds the maximum number of permitted defective pixels for the particular resolution specified by the majority of manufacturers.

The operation of the LCD Monitor is unaffected by bright or dark sub-pixels that may appear during the manufacture of the LCD Monitor panel. If the film of the liquid crystal does not function as intended while the client uses the LCD, the customer may observe bright or dark patches. However, until the number of bright and dark subpixels exceeds the maximum permitted level, this is not regarded as a fault (…)

According to LG’s pixel policy, the most you should put up with on a monitor with more than 12 million pixels (Wide QXGA+, 2560×1600 pixels), for instance, is 12 bright or dark sub-pixels.
