I had a run of dead pixel screens from laptopscreen.com too, but they did send out replacements and pay for return shipping. They seemed to be the only large place in the u.s. that had a no dead pixel gurantee and backed it up without issue. Lately all the screens from them have been fine.
I asked them if they check them for no dead pixels before shipping, they said no. They also said I could ask to have the screen checked before shipping, but that wasnt an every order deal, just after recieving a screen with one stuck pixel.
We use them when we can, I just think dead pixel policies are a joke. No ones gonna buy an 60 tv and accept 1 to 3 dead pixels, laptop screens should be no different.

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.

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.
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.

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.
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.

A defective pixel is a pixel on a liquid crystal display (LCD) that is not functioning properly. The ISO standard ISO 13406-2 distinguishes between three different types of defective pixels,
Similar defects can also occur in charge-coupled device (CCD) and CMOS image sensors in digital cameras. In these devices, defective pixels fail to sense light levels correctly, whereas defective pixels in LCDs fail to reproduce light levels correctly.
A bright dot defect or hot pixel is a group of three sub-pixels (one pixel) all of whose transistors are "off" for TN panels or stuck "on" for MVA and PVA panels.
A tape automated bonding fault (TAB fault) is caused by a connection failure from the TAB that connects the transparent electrode layers to the video driver board of an LCD.
TAB is one of several methods employed in the LCD-manufacturing process to electrically connect hundreds of signal paths going to the rows and columns of electrodes in layer 6 (the transparent electrode layer) in the LCD to the video integrated circuits (ICs) on the driver board that drives these electrodes.
If an LCD is subjected to physical shock, this could cause one or more TAB connections to fail inside the display. This failure is often caused by horizontally flexing the chassis (e.g., while wall-mounting or transporting a display face up/down) or simple failure of the adhesive holding the TAB against the glass. TAB faults require the replacement of the LCD module itself. If these connections were to fail, the effect would be that an entire row or column of pixels would fail to activate. This causes a horizontal or vertical black line to appear on the display while the rest of the display would appear normal. The horizontal failure runs from edge to edge; the vertical failure runs from top-to-bottom.
A stuck sub-pixel is a pixel that is always "on".RGB layer. Any given pixel will stay red, blue, or green and will not change when attempting to display an image. These pixels may only show up using certain applications
In LCD manufacture, it is common for a display to be manufactured with several sub-pixel defects (each pixel is composed of three primary-colored sub-pixels). The number of faulty pixels tolerated before a screen is rejected, is dependent on the class that the manufacturer has given the display (although officially described by the ISO 13406-2 standard, not all manufacturers interpret this standard the same way, or follow it at all).
Some manufacturers have a zero-tolerance policy with regard to LCD screens, rejecting all units found to have any number of (sub-)pixel defects. Displays meeting this standard are deemed Class I. Other manufacturers reject displays according to the number of total defects, the number of defects in a given group (e.g., one dead pixel or three stuck sub-pixels in a five-by-five pixel area), or other criteria.
In some cases, a manufacturer sends all screens to sale then replaces the screen if the customer reports the unit as faulty and the defective pixels meet their minimum requirements for return.

Dell offers a Premium Panel Exchange that ensures zero bright pixel defects on Dell Consumer, Professional, UltraSharp, and Gaming including Alienware monitors.
Defective pixels do not necessarily impair the performance of the monitor. However,they can be distracting, especially if the pixels are in positions where viewing quality is reduced.
Unyielding commitment to quality and customer satisfaction has driven Dell to offer a Premium Panel Exchange as part of the standard limited hardware warranty. Even if one bright pixel is found, a free monitor exchange is supported during the limited hardware warranty period.

The first thing you do when you purchase a new smartphone, laptop or LCD TV monitor is to check for dead pixels. More often than not, if you purchase a branded product such as Dell Monitor or Asus Laptop or Samsung Smartphone, you are guaranteed a 1 for 1 exchange during the warranty period. This cannot be said if the said item is of generic brand. Without further ado, here are 6 free tools to detect and fix dead or stuck pixels.
A stuck pixel is a bright dot of colour that fails to update when neighbouring pixels change. Stuck pixels are most noticeable when the rest of the screen is black. Stuck pixels are different from dead pixels. A stuck pixel is a single color – red, green, or blue – all of the time. A dead pixel is black instead. While it’s often possible to “unstick” a stuck pixel, it’s much less likely that a dead pixel will be fixed. While a dead pixel may simply be stuck at black, it’s possible that the pixel isn’t receiving power at all. A faulty pixel displaying the color white all of the time is known as a “hot pixel.”
DeadPix is an application that can help you fix pixels that are stuck on your screen. You can download the installer or download the portable version below. It’s also completely free! It can fix stuck pixels by rapidly cycling the color value of the stuck pixel. Please note that this tool does not provide a 100% success rate.
InjuredPixels allows you to easily check for defective (hot, dead or stuck) pixels on LCD monitors. InjuredPixels can be used to test a new LCD monitor before purchasing, or an already purchased monitor during the warranty period (as you may get a replacement according to the manufacturer’s dead pixel policy). InjuredPixels fills the entire screen with a primary or custom color, helping you to easily spot pixels that do not match the selected color.
You can easily cycle through colors, and clean or gently rub any area while testing. InjuredPixels is completely free, open source, doesn’t show ads, and requires no Internet and no extra permissions whatsoever. The program is easy to use: click or use the arrow keys to cycle through colors or right-click to get the menu with the main commands. InjuredPixels can be run directly without having to install it on your computer: just download the portable version and run.
Try to fix dead, stuck or hot pixels by yourself, before running back to the store! PixelHealer can help you try to fix dead pixels by yourself, before running back to the store! You can use it to fix dead, stuck or hot pixels on LCD or TFT screens, on desktop monitors, laptops or tablets.
PixelHealer uses the already tested concept that flashing RGB colors over a dead or stuck pixel will revive it. So let the repair window run for a while, then check to see if the dead pixel has been fixed or revived. And repeat the process if necessary.
The JScreenFix pixel fixing algorithm has been applied to over four million screens and is the most effective software solution available for repairing defective pixels. JScreenFix is a web app that’s very similar to PixelHealer, except that you don’t need to download anything to use it. That makes it suitable for a wide variety of platforms, and it’s notably the best solution for iOS and Mac devices at the moment. Works great on Microsoft’s Windows 10 and Apple’s macOS.Fixes most screens – Suitable for LCD and OLED. >60% success rate.
This is a simple test designed to make it easier to detect LCD “dead pixels” (pixels that are either stuck-ON or stuck-OFF) by displaying a series of solid background color pages for contrast.
Have dead or stuck pixels on your laptop screen or retina display? Keep replaying this video until the dead pixel or stuck pixel has been repaired/unstuck. This video fixed the stuck pixels on my Macbook Pro’s Retina display (UHD 4K), Though be warned it can take hours depending on the pixel.
If this method doesn’t work for you, Google the pen tip pixel method or contact the manufacturer of your display. This video should also work on smartphones, iPhone, iPad and tablets! Seizure warning – Do not watch the screen! Turn the screen away from you if possible and allow the video to run to the end, repeat the video if necessary.
Pixel combines two words, ‘ pix’ (picture) and ‘el’ (elements). Pixels can be referred to as ‘dots’ or squares, and these are the basic building blocks of a digital image. When lots of these tiny dots/squares are put together, they form a digital image. Every single pixel has three sub-pixels in red, green, and blue color. Transistors carry electric current to the sub-pixels; this current is why the change of color changes in pixels.
Pixels compose the images displayed on the computer screen, television, laptop, video games, smartphones, and the list goes on. A pixel is the smallest controllable element of an image or display that a computer can print or display.
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.
Click anywhere on screen to change the background color (red, green, blue, black and white) in order to identify the precise location of the pixel asleep, then drag the square from the center of the screen towards the area of the defective pixel and press it to start the flashing that will attempt to awake the pixel: it needs no more than 20 minutes to recover dead pixels, otherwise hardly be able to fix it.
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. You can fix the stuck pixels by calling them to do rapid changes. You need to run this program for a couple of hours. There is no warranty on the result, but you don’t really have anything to lose trying it out. Good luck.
The way the app works is quite simple: it basically fills the screen with the color selected by you, thus making any dead or stuck pixel clearly visible. It is recommended to experiment with several colors, as you might not notice the broken pixels from the first attempt – you can go with one of the default colors (black, white, red, green or blue) or you can specify a custom one. You can also set Dead Pixel Buddy to automatically switch between colors as often as you like – just modify the Time Cycle value and you are set.

A black spot on an actor’s cheek that’s definitely not a beauty mark. You keep an eye on it and realize it’s a dead pixel smack dab on your TV screen.
They’re more obvious to the viewer when the surrounding pixels are brighter in color. While they may seem like a cause for panic, these little black specks are actually normal.
A TV gets a dead pixel when the transistors fail to send power to the pixels to make them light up. When the pixel is not illuminating, it appears as a black dot on your screen.
Physical damage that causes internal issues may also result in dead pixels. Having your TV mounted or placed in an area where it is less likely to be hit or knocked over is the best practice.
According to manufacturers, one to five dead pixels is normal. The chances of never having at least one dead pixel throughout your TV’s lifespan are pretty slim.
ISO-9241 parts 302, 305, and 307 published in 2008 established the standard by which manufacturers specify the defects of their LCDs. Class 0 would mean that the flat panel display was completely defect-free while Class 3 would have 15 dead pixels.
To be on the safe side, this led to some premium manufacturers specifying their products as Class 1, with 1 dead pixel per 1 million pixels in the LCD matrix, when they could be specified as Class 0.
Do note that dead pixels should not be confused with stuck pixels. Dead pixels turn black because they no longer have access to a power source. This means they can’t light up.
No, dead pixels do not spread, nor can they get “worse”. However, it is possible to get a cluster of blacked-out pixels because the transistors in that area failed.
Because the pixels are next to each other, they appear as a bigger black dot on your screen. These dead pixel clusters are more noticeable than a few stray pixels found on two separate corners of your screen.
Expect, over time, that more of these dead pixels will pop up on your screen. Electronics do break down the older they get, and more pixels can go black when the TV is near its end of life.
No, in most cases, dead pixels are irreversible. They are better off repaired by a professional or replaced. However, some dead pixels can be revived at home.
If you have a Smart TV that can connect to a browser, you can run a dead pixel test. You can also connect your computer to the TV as a second display and run the test on full screen from your TV.
Make sure your screen is clean before running the test. Wipe it down with a dry cloth to get rid of any dust or dirt that could be mistaken as a dead pixel.
On your TV’s internet browser, open up a tool like Check Pixels to run a dead pixel test. The test allows you to check for dead pixels by flashing different solid colors to identify any unwanted black dots.
I don’t recommend other methods of reviving dead pixels that use pressure or heat. These methods are dangerous and can cause even more damage to your TV.
Keep in mind that a few dead pixels aren’t considered significant damage to the manufacturer. It’s only ever a concern if there are more than seven dead pixels, Techwalla says.
It is best to purchase from trusted brands. This way, you are more likely to buy a high-quality television and you can reduce the chances of getting a new unit with dead pixels.
Finding dead pixels on your TV screen is normal, even on a brand new unit. While these little specks of unlit pixels don’t spread to their neighboring pixels like a virus, they can be unsightly.
You can use online tools to help you look for them and jumpstart these pixels back to their normal programming. If those fail, it is best to have a professional check it out or have it replaced.
Most manufacturer warranties cover replacements if there are more than seven dead pixels. But to be sure, it is still best to go check your unit’s specific warranty.
Check the reviews as well as the credibility of the manufacturer. This ensures you get a quality TV unit with little to no dead pixels straight out of the box.
