fix stuck pixel on lcd panel in stock

That annoying dead pixel on your TFT, OLED, or LCD screen might just be stuck and easy to fix. We"ll show you how to do it. You can still return your monitor if this doesn"t work; nothing we recommend here will void your warranty.

Yes, you should test any new monitor for bad pixels. You can simply run your screen through a palette of basic colors, as well as black and white in full-screen mode using a tool like EIZO Monitor Test.

EIZO Monitor Test is an online tool that lets you find and eventually fix stuck pixels. It packs many options into a single test window, but it"s easy to use once you have an overview.

To test your screen, check all the boxes you want to include in your test. We recommend the default setting of having all boxes checked. If you"re testing multiple monitors, you can open the test on an additional monitor. When you"re ready, click Start test to launch the full-screen test window.

Below you see the first test pattern. Each screen has an explainer in the bottom right detailing what you should look for. Next, you"ll see a menu that lets you go from one test to the next on the left. Move through the black and white screens and all the solid colors (green, blue, and red) and check our screen. To exit, press the ESC key or the exit symbol in the top right.

This is a very thorough test not only meant to identify bad pixels but also powerful enough to test the quality of your monitor. Unfortunately, with Flash no longer supported by most browsers, you"ll probably have to use the executable version to make it work.

Move the mouse to the top of the test window, and a menu will appear. There is an info window that you can turn off with a button in the top right corner of the menu. Then click on the Homogenuity test point and move through the three colors as well as black and white.

Fingers crossed, you won"t discover anything out of the ordinary. In the unfortunate case that you do, let"s see whether it"s a stuck or a dead pixel and what you can do about it.

A stuck pixel, sometimes wrongfully referred to as a hot pixel, is defective because it receives incomplete information. Hence, it appears in one of the colors that its three sub-pixels can form, i.e., red, green, or blue. Strictly speaking, hot pixels only appear in digital cameras when electrical charges leak into the camera"s sensor wells. Sometimes, stuck pixels fix themselves.

In a dead pixel, all sub-pixels are permanently off, which will make the pixel appear black. The cause could be a broken transistor. In rare cases, however, even a black pixel may just be stuck.

Unfortunately, you can"t fix a dead pixel. You can, however, fix a stuck pixel. As I explained above, it"s hard to tell the two apart. Either way, these are the methods you can try:

Finally, you can try a manual method that involves rubbing the stuck pixel with a damp cloth or a pointy but soft item, like the rubber/eraser at the end of a pencil.

The tool will load a black browser window with a square of flashing pixels. Press the green button in the bottom right to go full-screen. Drag the flashing square to where you found the stuck pixel and leave it there for at least 10 minutes.

UDPixel, also known as UndeadPixel, is a Windows tool. It can help you identify and fix pixels using a single tool. The program requires the Microsoft .NET Framework. If you"re not on Windows or don"t want to install any software, scroll down for the online tools below.

Should you spot a suspicious pixel, switch to the Undead pixel side of things, create sufficient amounts of flash windows (one per stuck pixel), and hit Start. You can drag the tiny flashing windows to where you found odd pixels.

The PixelHealer lets you flash a combination of black, white, all basic colors, and a custom color in a draggable window with customizable size. You can even change the flashing interval and set a timer to close the app automatically.

Let it run through all colors in Auto mode to spot whether you have any weird pixels on your screen. If you do, start the fix, which will rapidly flash your entire screen with black, white, and basic color pixels.

Should none of these tools resolve your stuck or dead pixel issue, here is one last chance. You can combine any of the tools detailed above and the magic power of your own hands. There is a very good description of all available techniques on wikiHow. Another great step-by-step guide can be found on Instructables.

This works because, in a stuck pixel, the liquid in one or more of its sub-pixels has not spread equally. When your screen"s backlight turns on, different amounts of liquid pass through the pixel to create different colors. When you apply pressure, you"re forcing the liquid out, and when you release the pressure, chances are the liquid will push in, spreading around evenly as it should.

When all attempts to revive your bad pixel fail, the next best thing you can do is to make peace with it. One ugly pixel won"t break your screen, and eventually, you"ll forget about it. If the defect affects more than a single pixel, however, or just bothers you a lot, you can always replace your monitor.

First, check the warranty. The manufacturer or the marketplace where you purchased the monitor might cover dead pixels. Note that most manufacturers define a maximum number of allowable bad pixels for specific resolutions, and the warranty won"t apply until your monitor crosses that threshold.

Bright or dark sub-pixels can occur during the production of the LCD Monitor panel but does not affect the LCD Monitor functionality. The customer may notice the bright or dark spots if the film of the liquid crystal does not perform as expected while customers uses the LCD monitor. However, this is not considered a defect unless the number of bright and dark subpixels exceeds the maximum allowable threshold (...)

On a monitor with over 12 million pixels (Wide QXGA+, 2560x1600 pixels), for example, LG"s pixel policy says that 12 bright or dark sub-pixels is the maximum you have to tolerate.

Should all of these approaches fail to fix your dead pixel warrior, at least you"ll now know it"s not simple to fix, and, you might actually have to replace the screen.

You may experience a stuck pixel on a new or used LCD screen. If your monitor’s warranty has expired, or the manufacturer won’t replace the monitor because it considers one or two stuck pixels as acceptable, there are a few things that you can do.

However, they should help out in most situations, and therefore you might want to give them a try before you spend your money calling a specialist or decide on getting your monitor replaced.

This is obviously the safest method, but it’s not always effective. If you recently discovered a stuck pixel, you can try to turn off the monitor and unplug it for a day or two. When the damage is caused by overuse, this could help.

There are many websites that offer a stuck pixel fixing service. They work more or less in the same way, by flashing pixels and hopefully un-stick the ones that are defective.

You’ll find that many of them run with Flash, which is no longer available – fortunately, here’s one that you can still rely on – JScreenFix. JScreenFix is a free online service that can solve your problem of stuck pixels. You don’t have to download anything, so it’s not invasive nor harmful.

Visit the website jscreenfix.com and scroll down to find the Launch JScreenFix button – click on it. It will open a black screen with a square full of flickering pixels. The instructions pop up right there – however, what you’re meant to do is drag this square to the area where the stuck pixel is. Then, leave it for at least ten minutes.

If it doesn’t fix your stuck pixel on the first try, you can do a few attempts leaving it for a little longer. Usually, this method gets the job done, but it’s not a 100% guarantee.

*Safety note: If you have epilepsy, you should avoid using any of these stuck pixel fixer websites or software as they work with flashing erratic lights.

Any technique that implies applying pressure to fix a stuck pixel can potentially make more damage than good. Here you’ll find some precautions you should take to minimize these chances.

However, if you decide to do this, it’s at your own risk. Turn on your computer screen or monitor as the pixel needs to be working for the pressure methods to stand a chance.

Determine if you have hot, stuck or dead pixels – if you don’t know the difference among these, read the next section first. Only if the pixel is stuck, you’ll have a chance at fixing it with a pressure method.

Open a black image as background in full-screen mode or use a black browser window such as this. Either way, don’t just leave a blank signal. This again has to do with the fact that you need the pixel to have the backlight on. Make sure the screen is clean to avoid confusing dust with bad pixels.

Get a Stylus or Touch pen to put pressure on the monitor without damaging it. Otherwise, you can try using your finger wrapped with a microfiber cloth.

Some people recommend a heat method where you use a hairdryer to warm the spot while you’re putting pressure on the monitor to fix a stuck pixel. Others suggest using a hot water damp cloth to apply the heat directly.

However, you could end up with something worse than a stuck pixel. The pressure method already represents a small risk of damaging your monitor – if you add heat, you’re increasing that risk.

To understand the possible pixel problems that you can face – and whether or not you can fix them – you need to know that an LCD screen is made by pixels. Three sub-pixels form each pixel – one is red, one is green, and one is blue (RGB).

When you have a pixel defect, it means that one or more of the subpixels aren’t working as they’re supposed to. Let’s see how these can present. Dead pixels

Dead pixels show no light, and what’s the absence of light? Dark. So, if you see a black pixel on your monitor, it’s a dead pixel. These are more noticeable when you’re working with a white background. Stuck pixels

The third option is that you see a white pixel – these are known as hot pixels. That means that all three colors (red, green and blue) are always on – this results in white light. These are more obvious on a dark background.

So, now you know what type of faulty pixels you can run into and how you can identify them. At this point, you might be wondering how do stuck pixels happen?

LCD stands for liquid crystal display. These monitors are made with multiple layers. In the far back, they have the light source that illuminates the screen with white even light.

The reason why we don’t see a fully white screen all the time is that there’s also a layer with color filters. This layer has a red, green and blue filter per pixel (RGB) – each of those would be a sub-pixel.

Two of these ‘blocking’ layers are polarizing filters – the first one filters the light waves in one orientation and the second one in the opposite direction.

Anyway, all this explanation is to tell you that stuck or dead pixels often happen because there is a broken transistor that fails to supply voltage to a certain pixel or sub-pixel. Keep in mind that there are two types of LCD monitors: TN (Twisted Nematic) and IPS (In-Plane Switching). On TN monitors, the default without voltage is on. So, if the transistor is not supplying power, the pixel won’t be dead (black) but hot (white). On IPS monitors, it works the other way around.

Most of the times, the damage in the transistor is a manufacturing defect. However, it can also happen because the monitor falls or it suffers physical damage.

So, you can use a dead pixel test. There are some free ones online such as the one from LCD Tech. You simply need to click on the Start Test button, and it will automatically enter full-screen mode in complete white.

Make sure your monitor is clean to identify dead pixels better. Because the screen will be completely white, you can also use this to find stuck pixels. On the other hand, a hot pixel won’t be visible – for these, you would need a dark screen.

Sometimes you can have bad luck and receive your new computer or monitor with an original pixel fault. In most cases, these are dead pixels, and therefore, there’s nothing you can do except try and exchange your monitor with the manufacturer.

Keep in mind that these are just good practices that can extend the life of your LCD screen. Unfortunately, there isn’t a full-proof method to avoid getting stuck pixels.

Stuck pixels are the most fixable problems you can have with your pixels. A stuck pixel can disappear on its own, or you can use other methods to try to fix it – in this article, you’ll find some of them.

It depends on the class of monitor that you have – only class I monitors shouldn’t have any dead pixels. For other classes, most manufacturers will consider one dead pixel as acceptable. This means that they probably won’t replace your new monitor because of it.

Of course, if this acceptable to you, it’s a different matter. It often depends on the location of the dead pixel and the size of the monitor. If you find it unacceptable, you should still give it a shot at the guarantee and see if you can have it exchanged. Check the ISO 13406-2 to see the ‘acceptable’ standards according to the type of monitor.

No, dead pixels won’t go away on their own – most of the times, they’re not even fixable. Before you give up, though, make sure the pixel is really dead and not stuck – because stuck pixels can go away.

Dead pixels are more noticeable in light areas because they are black. Also, it depends on the size of the pixel, the size of the display and the resolution. Keep in mind that once you know it’s there, you’ll keep noticing it.

If your warranty is valid and you can get your device exchanged, that’s the best way to do it. Otherwise, determine what type of pixel problem you have.

There are a few different methods to try to fix stuck pixels – although none of them is certain. On the other hand, hot and dead pixels can’t be fixed.

I hope you found this guide helpful. If you have any questions or want to share some tips on preventing, detecting, and fixing faulty pixels, please leave a comment.

A dead pixel can be a huge pain, whether it"s on your smartphone, desktop monitor, or laptop. Fortunately, even though a dead pixel isn"t a great sign of monitor health, there are ways you can sometimes bring that pixel back to life.

If your device is no longer under warranty or you don’t want to take it to a professional, don’t despair. Here"s how to fix a dead pixel in just a few steps.

Step 3: Let the JScreenFix app run for at least 30 minutes. Drag the white noise window to where your stuck or dead pixel is located, and then let it run for half an hour. JScreenFix claims it can repair most stuck pixels in under 10 minutes, but giving it plenty of time to work never hurts. Try using it several times if the first run wasn’t successful.

Keep in mind that this method uses both HTML5 and JavaScript and may work with LCD or OLED screens. If it doesn’t work, though, you could always try one of the platform-specific tools below.

PixelHealer is an entirely free application from Aurelitec that fixes pixel problems. It’s compatible with Windows 7, 8, 10, and 11. Once downloaded, PixelHealer will present you with a colored box window and a settings menu. It is important to note, though, that users who are sensitive to flashing images should not look directly at the box/app window, because as the app runs, the window will then flash multiple colors in quick succession.

PixelHealer is more likely to work on a stuck pixel that shows signs of life than a dead pixel, which may stay unresponsive, but there’s a chance it can fix both, so give this dead pixel fix a try regardless of how your wounded pixel is behaving.

With such a straightforward name, you know that Dead Pixels Test and Fix (DPTF) is a quick and easy dead pixel fix for locating and potentially repairing dead or stuck pixels. It’s a free app and features an interface that is both self-explanatory and easy to navigate. DPTF assumes the same process as its competitor apps, using a series of solid color blank-outs on your screen to reveal damaged pixels.

The developers recommend that you let DPTF run for at least 10 minutes to fix all of the pixels, but we had better results when we left it running for a couple of hours so it had time to fix all of the dead pixels. You’re going to need to have a full battery or your device connected to a power source while you execute this tool.

DPT 2.20 – A Windows application to help locate and identify dead/stuck pixels. It also has a pixel exerciser built in to possibly get lazy pixels working again.

Apply pressure through the folded washcloth with the instrument to exactly where the stuck pixel is. Try not to put pressure anywhere else, as this may make more stuck pixels.

Remove pressure and the stuck pixel should be gone. This works as the liquid in the liquid crystal has not spread into each little pixel. This liquid is used with the backlight on your monitor, allowing different amounts of light through, which creates the different colors.

Display a black image, which will show the stuck pixel very clearly against the background. (It is very important that you are showing a black image and not just a blank signal, as you need the backlighting of the LCD to be illuminating the back of the panel).

Use the rounded end of the pen to gently tap where the stuck pixel is - not too hard to start with, just enough to see a quick white glow under the point of contact. If you didn"t see a white glow, then you didn"t tap hard enough, so use just slightly more pressure this time.

Display a white image (an empty text document, or sending your browser to about:blank and going to fullscreen with F11 is good for this) to verify that you haven"t accidentally caused more damage than you fixed.

This method is useful if large areas are discolored or even black. It works best with laptops, but it may work with separate monitors, too. By using this method, you are exposing your computer to the risk of damaging the processor and/or other components by overheating. If you do this, you should be willing to accept the loss of your computer (for laptops), or monitor (for stand-alone screens). You should backup your data before trying this method. In particularly bad cases of damage, the effect may not work completely, or the fix may not be permanent.

Close the laptop lid almost completely, but don"t let it close fully - This will keep the laptop screen turned on indefinitely. You may take a small paper pamphlet or something soft and place it on the keyboard to prevent gravity from closing the lid.

Let the computer sit for several hours or even days in this condition. You may check on it as frequently as you like. The heat generated will cause the liquid crystal to flow more easily into the areas that were not formerly filled.

If the pressure and tapping don"t work directly on the stuck pixel, start moving outward around the stuck pixel. If you see the pixel flicker while doing this then you know where you can focus the pressure and tapping techniques rather than directly on the pixel.

Many people report success with this technique, but these instructions won"t work in every case. It may take a few attempts to make sure you are pressing exactly on the stuck pixel. These instructions will fix "stuck" pixels, not "dead" ones. Dead pixels appear black while stuck pixels can be one

constant color like red, blue or green. An alternative, but similar technique involves gently massaging the stuck pixel with a warm damp (not wet) soft cloth.

If these instructions don"t work, you can hopefully get the monitor replaced through your manufacturer. If your monitor falls under the specifications of replacement, get in contact with the manufacturer to set up replacement plans.

LCD displays are composed of multiple layers. Each layer is separated by very small glass spacers. These spacers and the individual layers are very delicate. Rubbing an LCD panel with a finger or even a cloth can cause the spacers to break and cause further issues beyond the original pixel fault. As such, most repair technicians with service certifications are trained not to use the rub or tap methods - use them at your own risk.

Most LCD manufacturer warranties for LCD displays will cover replacement of the panel when the display reaches a certain number of pixel anomalies. These warranties, however, generally will not cover damage caused by rubbing the screen so use extreme caution and contact the manufacturer before proceeding to see if you qualify for repair or replacement.

Your monitor is made up of millions of pixels. Each pixel is a group of red, green and blue subpixels that combine to create the images you see on your computer screen. When a few are dead or stuck, it can be super distracting.

If you’re having trouble identifying them, though, we’ll show you some tools to use, then tips for ridding your monitor of these tiny little eyesores.

A dead pixel occurs when an entire pixel or a group of subpixels remain dark even when they’re supposed to be on. Since this implies that the pixel or group of subpixels are no longer powering on, they’re harder to fix than stuck pixels. In most cases, dead pixels are lost forever.

A stuck pixel occurs when one or two of the color subpixels remain activated even when they’re supposed to be off. For example, the blue subpixel might get stuck, so the entire pixel will display a different color than what is intended.

To see what’s going on, you can enlist software to help. Try a third-party download like InjuredPixels for Windows. If you’re on a Mac or don’t want to download anything, go with a browser-based solution like LCD DeadPixel Test.

Most monitor manufacturers have a return policy for dead and stuck pixels. They’ll usually replace a monitor if it has more than several pixels stuck in a single color or brightness setting. Since dead pixels are difficult to fix, replacing your monitor via the manufacturer’s warranty is your best route.

You can go the web browser application route with a site called JScreenFix. The free service claims to fix most stuck pixels within 10 minutes by using an HTML5 “PixelFixer” tool.

And since it’s HTML5 and JavaScript-based, there’s nothing to install. All you have to do is bring up the website, drag the PixelFixer window over the stuck pixel area then leave it on for at least 10 minutes.

After detecting your monitor’s stuck or dead pixels, use PixelHealer’s flashing color box on the affected areas to try and jolt the pixels back into shape. The site claims that the tool uses the already proven method of using flashing RGB colors to restore a stuck pixel or even revive a dead one.

If your monitor is out of warranty and none of the pixel fixing software methods are working for you, you have two choices. Either you learn to live with a few stuck or dead pixels here and there, or, if you’re brave enough, there’s a last-ditch method you can attempt.

First, take note of the location of the stuck or dead pixel. Then turn off your monitor and try applying gentle pressure on the affected area to “massage” it back to life. Use something with a narrow but flat edge like a pencil eraser or a pen cap. To avoid damaging your screen, wrap it with a soft, damp microfiber cloth.

The idea is that by applying gentle force, you might coax the pixel back into its proper alignment. If not done correctly, this method can actually create more dead pixels, and extreme caution is required.

Knowing how to fix dead pixels is a good skill to know. If you’ve noticed unusual spots on your display, you might be dealing with stuck or dead pixels. Fortunately, these pixels are usually harmless and can be detected using special pixel tests.

Dead and stuck pixels can appear on LCD screens of all kinds. This includes monitors, phones, and camera displays. It’s easier to spot them on larger displays, though.

If you’re using a camera, carefully look at your LCD display as you take photos. Are there any spots that stay in the same place no matter how much you move your camera? Those spots are dead or stuck pixels.

There’s a distinct difference between stuck and dead pixels. If you’re completely sure that the pixels on your screen aren’t dust, you need to identify them.

Stuck pixels are usually red, green, blue, or yellow. Dead pixels are black. No matter how much your screen changes, those pixels will remain fixed in one spot and won’t change their color.

Keep in mind that stuck pixels can also be black or very dark in color. You might accidentally mistake them for dead pixels. To make sure that they’re not dead, you need to use a dead pixel test. More on this later.

Stuck pixels are much easier to remove than dead pixels. If you’re sure that there’s a dead pixel on your screen, you’ll probably have to hire a specialist or replace your display.

Here are a few simple websites that let you check for dead pixels using solid colors. They basically do the same thing, but one of them might be more compatible with your device/browser than the other.

You need to be in full-screen mode. Make sure you wipe your screen beforehand so that you don’t accidentally mistake a speck of dust for a dead pixel!

Click on each color. If you don’t notice any unusual spots (black or any other color) on your screen, it’s likely that you don’t have an issue with dead or stuck pixels.

Some users recommend rubbing a dead pixel using a cloth to get rid of it. This might work temporarily, but it will damage your display in the long run.

Too much rubbing can damage even more pixels on your screen and lead to serious problems. If none of the solutions work, the best way out is to contact a specialist.

As mentioned previously, dead pixels are usually impossible to remove without professional help. However, you need to make sure that those dead pixels aren’t secretly stuck pixels or simply dust particles.

This is a very simple and seemingly straightforward method. But it might be the best solution to your problem. If your screen appears glitchy, it might simply need to be refreshed.

Use a screen-cleaning spray and a cloth to wipe your display. Make sure you don’t apply too much pressure or else you might damage your screen. A few gentle swipes might get rid of the problem.

If the options above don’t work, JScreenFix might be your best solution. This is a website that anyone can use for free. You don’t need to download any programs or extensions to use it. Best of all, it promises to remove stuck pixels in less than 10 minutes.

What JScreenFix does is fix stuck pixels. If you think you have a dead pixel, you can try this method as well. For this to work effectively, you need to know where exactly your stuck pixels are located.

Your job is to find the stuck pixel and drag the box to it. Leave it there for a few minutes. This should get rid of any unusual pixels on your display.

If you’re sure that the pixel is dead (and not stuck), then you’ll need to see a specialist. There are a few methods for fixing dead pixels, but most of them don’t seem to work effectively.

No. More often than not, stuck pixels are temporary. You might have to try a few methods to remove them. There are a couple of programs that promise to remove stuck pixels quite easily.

Dead pixels usually don’t spread. They’re usually a small fault in a display. If they do spread, you might need to hire a specialist or replace your screen.

Make sure you clean your display, take a dead pixel test, and use JScreenFix to get rid of the pixels. It’s likely that this will fix the problem and prevent you from consulting a specialist.

If you suspect you have one, but you aren"t sure, investigate more closely with tools like the Dead Pixels Test or CheckPixels.com. These programs often display solid colors on the entire screen, allowing your eyes to more easily pick out pixels that aren"t functioning properly.

Dead pixels can"t be fixed in most cases, but you can sometimes revive those pixels. We have a few solutions for you to try before you send your device out for repairs.

Dead pixels are not the same as stuck pixels. These pixels look almost the same, but there"s an important distinction. A dead pixel won"t turn on, whereas a stuck pixel is permanently on. Since it"s permanently on, it typically appears as a bright, persistent dot on the screen, and is either red, green, blue, or white. If a problematic pixel is dead, it should look like a small black rectangle.

The most common cause of dead pixels is a manufacturing defect. Undetectably small errors in assembly can result in a handful of dead pixels among the millions of functional ones.

It may go away on its own, but there"s no telling how long it will take. You might have the dead pixel for the remainder of the device"s life, or it might go away in a week.

Many manufacturers have warranties that cover dead pixels, so check your device"s warranty to see if this situation applies to you. Most display manufacturers require a minimum number of dead pixels before the screen can be replaced.

You can examine the dead pixel policies of Acer, Apple, Dell, LG, and Samsung, but the best source is always the device"s specific warranty documents.

You may come across other methods of fixing this problem yourself, including "pressure" and "heat" methods. We do not recommend trying these methods as they can make the problem much worse if not done properly!

There isn"t a lot you can do to fix dead pixels; most people tend to buy a new tablet, computer, or TV when pixels start going bad. If you"re not comfortable with replacing the screen yourself (most people aren"t), then the next step is to find a local repair shop if your device is no longer under warranty or break out the wallet.

By and large, dead pixels are considered to be fairly normal when it comes to LCD displays—for example, Dell says dead pixels are not uncommon. And the larger the screen, the less likely we are to notice a few dead pixels among thousands of active ones.

Everyone has their own opinion on what they consider "acceptable" when it comes to dead pixels, but generally it depends on whether or not you even notice them in the first place. But generally speaking, anywhere from one to five inactive pixels is considered okay according to industry standards.

On plasma screen TVs and LCD computer monitors, a pixel is a tiny square that can flash red, green, and blue light at varying intensities. The combination and intensity of the red, green, and blue lights determines the final color shown on the screen. Occasionally, the liquid in an LCD monitor can redistribute itself in such a way that one of the pixels gets stuck on a certain color. You may notice a dot of white, bright red, lime green, or deep blue that never seems to go away; this is a stuck pixel. Luckily, stuck pixels are easy to fix at home with nothing more than your pinky finger and special image or video.

One trick for fixing a broken pixel is to gently massage it with your finger. Even though technicians advise against rubbing the screen of an LCD monitor, many people find that gentle pressure will return a stuck pixel back to normal.

Sometimes you can correct a pixel by making it flash on and off, or making it flash different colors. If you shrink the browser screen around this image and move the image across the broken pixel for a minute, it may coax the pixel back to normal. Simply drag the image around so that the pixel is on the colored part, then on the black part, then back and forth, back and forth.

For a more stubborn pixel, you may need to play rapidly flashing colors over the pixel using a video or animated image. If you gently rub the stuck pixel while the video plays, your pixel should right itself in no time. Try this animated GIF:

Or this video on YouTube. Any other bright and fast video will work too. Warning! This video may give you a headache, so close your eyes while it plays!

If you have a mobile device with internet access and an LCD screen, these tricks can also cure stuck pixels on the touch screen. One thing you should never do is poke the pixel with pointed object such as a pen or pencil tip. This is more likely to damage pixels than to fix them. If you cause more damage, it may void your warranty.

Also keep in mind that these tips won"t revive a truly dead pixel. A dead pixel is always black, since neither the green, blue, nor red lights can illuminate.

I am going to show you how to fix a stuck pixel on your LCD monitor. Stuck pixels are really annoying and just plain look bad. Over the past few years I have had to fix SO many stuck pixels. It"s not that hard to do and usually only takes a couple of minutes. Enjoy!

This will only work on LCD monitors, but this includes computer LCD monitors, laptop screens, cameras (the screen might have a hard protective shield over it that you will have to take off), and hand-held systems (will most likely have a hard protective shield). Does anybody know if this will work with an OLED screen? I think that it will, but I"m not positive.

Note: This will only fix stuck pixels. Not dead pixels or hot pixels. A dead pixel is when the pixel is always off. It is easiest to spot a dead pixel against a white background. The pixel will appear to be non existent. It will look darker than the stuck pixel in the image below. A hot pixel is when the pixel is always on. It is easiest to see against a dark background. The pixel will be bright white. A stuck pixel will usually the red, green, blue or yellow, but can also be a light black color (pictured below). A stuck pixel is caused by a manufacturing defect in which it leaves one or more sub-pixels permanently turned on or off.

By the way, the picture that I took is a bad example of a stuck pixel. Because it is black, one might think that it is actually a dead pixel but it is not. It just so happened that all of the sub-pixels in that pixel were permanently turned off. The next time I see a dead pixel on a computer that isn"t black, I will update the picture because the current one is a bad example.

This is the most traditional method. It fixes the stuck pixel by rapidly flashing different colors to try to get it to change. This method works very well, but if you do it for to long, it can actually create more stuck pixels. Get it here or download it below. The site claims that it can also reduce burn in on plasma displays but I have not tested it yet.

Open the java applet and resize it so that the window is very small. Now move the window over to where your stuck pixel is. Leave it be for five minutes than close the window and see if it"s fixed. If its not than repeat again for another five minutes. The site says that it may take up to 20 minutes but I have found that it usually works within the first 10.

This method is done by placing a damp (not wet!) paper towel over you monitor. Place your stylus or blunt pencil tip on the paper towel over where the stuck pixel is. You have to place it exactly on the stuck pixel. Now turn of your monitor and apply a small amount of pressure to the stylus / pencil. Wait two seconds and then turn your monitor back on. Your stuck pixel should be fixed! If it is not, try repeating but this time, apply a little more pressure.

This method works because a stuck pixel is a pixel in which the liquid in the liquid crystal has not or not completely spread to this pixel. The backlight uses this liquid and lets different amounts of light through. This affects the color of the pixel. The pressure helps the liquid in the liquid crystal move around.

This final method works but can easily create more stuck pixels or even do some real damage so be careful. First you need to display a dark color / image over your stuck pixel. (Make sure it"s really showing a dark color / image and not just a blank signal) Take the back of your stylus, or another small, blunt object, and lightly tap on the stuck pixel. You should briefly see a white spot where you tapped. If not, then tap a little harder. Keep tapping, each time tapping a little harder. This should only take about 5-10 taps. This should correct the stuck pixel. Be careful thought, because doing it too many times may cause damage to your monitor.

I have a new ASUS XG49VQ monitor, and I have had to return the first one due to over 20 stuck pixels. This one (monitor #2) had only one. So, I decided to live with it; that is untill this morning. I started to tap, then smack the side bezel of my screen. This seemed to move my stuck pixel. Then I smacked around more. This created more. I then started to flick my screen at each point. They started to subside. I then came across this instructible, and now I just have to press lightly on one that pops up and it fades back into submission. I suppose I found out why this ultrawide, entry level HDR monitor was only 799.99 brand new. LOL. Thank you for the advice, saved me from returning and getting a 3rd unit, or breaking down and just buy another monitor.

Hi, i have a question: can stuck pixels be fixed if they are all in a straight line that comes down across the screen? I m trying all these methods on my IMAC but its not working. Can you help me out?

Can you describe it more? Is it a vertical or horizontal line, or is it a diagonal line? Is it a solid line, or is it a bunch of stuck pixels that just happen to be in a line-like shape? If it is a solid vertical, or horizontal line, then it is a faulty lcd, and there is nothing you can do. Also, is your iMac the newer one that is aluminum and black? If it is, than the display has a glass/plastic plate over the lcd making method 2 & 3 useless.0

They can get some image retention in very odd situations... but it takes months and months of a static image for it to happen... while a plasma screen will have image retention in a matter of minutes.

99.99% of regular pc users would never notice image retention unless they never turned their monitors off and always left the exact image on the screens all day long 24/7 for years.

Plasma and even the newer OLED screens have it bad. Its why OLED"s high cost, and its poor pixel lifespan make it a fairly useless tech since for much less money you can get a mainstream LCD/LED display and with new tech like HDR, the contrast ratio is on footing with OLED but has the pixel life and almost zero chance of image retention, makes OLED very unwelcome unless it became cheaper than LCD screens.0

As others have mentioned this is either a video card issue or bad/dying LCD column driver. The latter are not fixable (to the best of my knowledge.) while according to the poster above the former are a silent recall issue for the iMac.0

This actually worked. I just noticed 4 dark/dead pixels on my screen (noticeable on a while image). I used that UDPixel program for around 30 minutes and it didn"t work by just using it by itself.

But i kept it running while also using a damp paper towl and used my finger and just rotated it around a bit on the pixel for a few seconds and it fixed all 4 dead pixels.

If it doesn"t work for you, keep trying and let your screen warm up a lot and run that pixel program to really work it up and use some massage action on the area with a bit of gentle pressure with your soft finger and see how it goes. I wouldn"t use a solid object. Your finger and paper towel is better because its nice and soft.

As some mentioned in other comments, if it happens again just keep doing it and it should go away again and is this is a very nice trick... My current monitor is a 2560x1080p LG ultrawide (34UM67). But i"ve got a really old 15 year old lcd monitor with a dead pixel i want to try this out and see if it works on it.0

I really had my doubts that this"d work, it"s a hardware problem, and a software generally cannot fix hardware-hence I tried the pressure methods first.

Tried the third method using a smooth metal pen button (the click-click one!), and it worked after a few taps! Thanks! Finally my 4-year black pixel went away! Bye bye!0

StuckPixelTool is easy to use app which is able to find and repair many kinds of display problems, such as stuck, defective or broken pixels (variations: stuck sub-pixels, dark dot defects, bright dot defects, partial sub-pixel defects, etc.), backlight bleed and screen burn-in (screen burnout, bad screen glow, image burnin or ghost image (screen ghosting), colloquially known as screen burn.

A stuck, defective, broken or even "dead" pixel is a point that does not display its color correctly, most stuck pixels are visible when the rest of the screen is black StuckPixelTool is able to analyze and fix most of them in less than 10 minutes.

NOTE: If your problem is not resolved and your pixels are still not cured within a several hours please try to turn off your device for a few minutes, and after a while try to start the fixer again.

There is also available Full version of the application, that contains no ads, has new features and offers access to the desktop versions, more information can be found here: https://blueburn.itch.io/stuckpixeltool

Bought a new smartphone or want to check on the old smartphone matrix display? In this program you can test your LCD screen for the presence of dead / broken pixels and repair it. You can detect any stuck or dead pixel on your LCD screen.

If you detect any stuck or dead pixels you will be able to try to cure them. Provide easy way to fix the stuck pixel. The program will try to use different means for the treatment of stuck pixels. Also works for screen burn-in. Start and wait on the smartphone or tablet this app until the dead pixel or stuck pixel has been repaired or unstuck.

Dead pixel is stuck point or several points of the matrix screen, which does not properly reflect the color. Sometimes they are almost invisible, and you can be the owner of them without even noticing it. There are several treatments for dead pixels screen. Mechanical - physical impact directly on the affected area and a soft-that and it has me. We strongly recommend not to use the first method is for advanced users, as it is dangerous for the screen matrix.

The program can repair: Partial sub-pixel defects, Stuck sub-pixels, Dead or Broken (bad) pixels, Stuck versus dead pixels, Dark dot defects, Bright dot defects, phantoms (matrix burnup).

If within a few hours of program works the pixels is not revived, so they can not be brought back to life in this way - contact the service center. Fix your screen with this programm.
