Good luck getting it fixed. That black spot is a dead pixel, a malfunctioning electronic dot among the millions that make up a typical display. And manufacturers of

"This is one of the things nobody ever wants to talk about in the industry," said Paul Semenza, an analyst at research company iSuppli. "The reality is that there are a lot of (screens) that aren"t quite up to snuff floating around, and they end up somewhere."

Sometimes they end up in your new notebook, as San Francisco engineer Rik Wehbring discovered a few years ago. The screen on his new Dell laptop turned out to a have a dead pixel.

Under Dell"s policy, which considers a screen defective only if it has six or more faulty pixels, Wehbring didn"t have a problem. To Wehbring"s eyes, he did.

Wehbring said Dell customer service told him he could send the screen in for repair, but he"d get a refurbished unit, and those were allowed to have as many as seven bum pixels. Instead, he took advantage of the company"s 30-day return policy and sent back his laptop, later using the refund to gamble on another Dell. The screen on the new laptop was fine, but the initial experience left a bitter aftertaste.

"The real issue is truth and language--broken is broken," he said. "They were trying to tell me I was silly for believing a dead pixel is a bad thing."

Dell spokeswoman Mary Fad said the company developed its dead-pixel policy to be brief and comprehensible to customers. But Dell can be flexible in interpreting it, she said, realizing that some dead pixels are more aggravating than others. "It"s something that"s a little subjective," she said. "We try to work with customers on a case-by-case basis."

Dead pixels are the result of flaws in the glass sheets that go into displays. Inevitable glitches in the manufacturing process mean that some pixels don"t illuminate properly--or at all.

John Jacobs, an analyst at research firm DisplaySearch, said the prevalence of bad pixels in consumer devices tends to change with the display market. When supplies are tight, gadget makers

"The market for displays is pretty bad right now, so the (manufacturers) can raise the cosmetic specs and get away with that," Jacobs said. "If the market gets really, really tight, they"ll change those policies to keep costs down...You"re better off selling another 10,000 laptops and having 50 more returns than having to bump your prices way up."

"This issue is akin to buying a new car and being told that there might be a couple of dents in the body panels, or new eyeglasses and being told that the lenses might have some scratches on them."

It"s possible to make devices whose every panel is perfect, as shown by standards for industries such as medical-imaging devices, where one bad pixel can mean "they"re going to cut you open thinking that"s where the tumor is," Jacobs said.

But applying such stringent quality standards dramatically raises the price of the finished device, as more than half the display glass the manufacturer buys has to be rejected because of flaws. Instead, device makers accept a certain number of defects and let the buyer beware.

The trick comes in figuring out just what your gadget maker considers to be a defective screen. Some manufacturers, such as Dell, set specific policies laying out how many pixels have to conk out for a display to be defective.

While Dell"s policy is relatively straightforward, some, such as those belonging to Acer and IBM, set complex formulas that distinguish between "bright dots" and "dark dots," the location on the screen and other factors.

Online retailer Newegg.com is one of the few stores that applies a uniform and widely publicized dead-pixel policy. Each LCD monitor listed on the site includes a reminder that the store will only replace if it has eight or more dead pixels.

"Not everybody"s forthcoming with that kind of information," said Jommy Gayoso, director of sales and merchandising at Newegg. "We believe customers are better off if they know what they"re getting into with a purchase."

"We"re seeing a shift toward zero defects," iSuppli"s Semenza said. "Several years ago, the manufacturers were basically saying that if there"s not three (dead pixels) in a row or a cluster, they don"t count--all these nitpicky things that put the risk on the consumer. It"s like saying that as long as three wheels work on your car, it"s OK. It"s clearly not something consumers want to hear, and the manufacturers are having to respond."

Ithaca, N.Y.-based Web developer Teri Solow said she appreciated the clarity of Nintendo"s policy for the DS. Even though the company basically promises

to fix any screen defects bad enough to annoy the consumer, Solow decided that the bum pixel or two on her player weren"t noticeable enough to warrant replacement.

"Dead pixels bother some people more than others, and I"m sure there are many people out there who would be much more upset at getting one dead pixel in their DS than I was at getting two," Solow said. "By giving everyone the option to get their screens replaced, Nintendo is ensuring that everyone who cares deeply about such things will end up happy."

Apple Computer employs a similarly vague policy for its PowerBook laptops, desktop displays and other products, saying an undetermined number of "pixel anomalies" are normal in such products, and Apple will decide when a problem is bad enough to warrant service.

Canadian filmmaker and comedian Andrew Currie said he learned of the policy when he bought a PowerBook a few years ago and discovered several dead pixels on the screen. The screen was replaced, but only after much haggling with Apple.

"I had absolutely no idea, and my first reaction to hearing the policy was, "Well, I never agreed to that!"" Currie said. "This issue is akin to buying a new car and being told that there might be a couple of dents in the body panels, or new eyeglasses and being told that the lenses might have some scratches on them."

DisplaySearch"s Jacobs, formerly a global supply manager at Apple, said the company"s pixel policy is designed to put the onus on consumers. "Basically, Apple has a policy that if you make a stink, they"ll replace it," he said.

Currie later bought one of Apple"s Cinema Display desktop monitors and negotiated with the retailer to make sure he eventually got one without bad pixels. He said Apple and other manufacturers would serve customers better by adopting zero-tolerance policies on bad pixels.

That"s not a bad idea, Jacobs said, given that most customers won"t notice or complain about one or two bad pixels. For those who do, a simple "we"ll fix it" policy like Nintendo"s ensures goodwill.

"It"s cheap customer love, saying, "We care, we"re going to give you the best-quality product,"" Jacobs said. "But the number of people who actually complain and do something about it is still going to be pretty small."

Semenza, however, said dead pixels will become more rare through a combination of improvements in manufacturing processes and market forces, especially as flat-panel displays proliferate in the home. "For TVs, any defect is unacceptable," he said. "If you"re asking somebody to pay $2,000 for a

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.

Experiencing dead or stuck pixels on a TV screen can be annoying. When this happens, most TV owners will resort to getting a replacement TV, an expensive and time-consuming affair. The good news is that annoying stuck or dead pixels on your TV can easily be fixed without resorting to buying the best TV. If you are wanting to buy a new TV, you have some options. If you want you can get some with the latest and greatest apps and resolution. However, if you don’t want or need all the newest tech, you can check out the top-rated dumb TVs.

Most TV owners don’t know that they can fix dead pixels on their TV at home. Better yet, if done well, you won’t void your warranty, and it’ll save you a lot of time and frustration. We’ve compiled a detailed guide on how to fix dead pixels on a TV screen.

TV screens are made up of thousands of pixels. These are small squares of light. Each pixel has three sub-pixels made up of green, red, and blue. These sub-pixels will change depending on the color they are required to project.

Therefore, if your TV pixel is showing a single color, it is stuck. This means one or more of the sub-pixels are lit up and won’t adjust color. However, if it’s black and doesn’t light up, it’s dead. This means none of the sub-pixels on the screen will turn on, regardless of what’s showing on your TV screen.

So, what causes dead pixels on TV screens? The most common reason your TV has dead pixels is due to failed power connections. The pixel transistor fails to recognize or receive electric voltage that tells the pixel when to light or change color. Additionally, you can read our article on how to fix a black spot on the TV screen to learn more about dead and stuck pixels.

Drop damage or trauma can also cause dead pixels. They can also form when a user constantly leaves static images on the TV screen for an extended time. You should avoid this even when you think it’s an energy-saving tip for your tv.

How to Fix Dead Pixels on TV ScreenIt is essential to note that TV owners can’t permanently fix dead pixels on their screen display. However, it is possible to fix a stuck pixel.

TV owners could also wait for the dead/stuck pixels to disappear on their own. Sometimes, dead pixels go on their own, but there’s no estimated time on how long this could take. Letting the pixels disappear on their own is also another way to fix lines on tv.

Try using a third-party application on the web. For example, there are free screen fixing applications (JScreenFix) on the web that can fix your stuck pixel in less than 10 minutes.

Apply some pressure on the area where you identified the dead pixel. You mustn’t put pressure anywhere else. This could trigger more dead pixels on your screen.

If the dead or stuck pixel doesn’t disappear, replace the screen. Depending on your manufacturer, the warranty covers dead pixels. However, it is essential to note that most manufacturers will need a minimum number of dead pixels before replacing the screen on warranty.

If you are 100% sure your TV has dead pixels, you might need to visit a specialist. There are a few methods that could fix dead pixels, however, they are not very effective.

TV owners could wait for the dead pixels to disappear on their own. Sometimes, dead pixels go on their own, but there’s no estimated time on how long this could take.

STAT:There were an estimated 119.9 million TV households in the U.S between 2018 and 2019. According to surveys, the average U.S consumer spent 238 minutes daily watching TV in 2017 (source)

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.

Buying an LCD monitor these days is both easier and harder than ever before with much lower prices and wider selection. One thing that remains a mystery is how dead pixels are widely accepted as the norm by most manufacturer and retailer warranties. Some companies only accept exchanges or returns if the monitor has as many as 8 dead pixels, or some combination of dead and stuck pixels in certain formations. Apparently there is not enough consumer demand for perfect LCD monitors, allowing companies to get away with this for so long.

If you do demand a perfect LCD monitor with no dead pixels, there is hope. There are certain retailers that offer liberal return policies on monitors (and other items), allowing you to exchange if pixel problems should arise. Let’s take a look at some of them below.

Dell is actually one of the best places to buy LCD monitors due to their no-hassle 14 days return policy. If for any reason you are unsatisfied, you can return or exchange your order within 14 days. Because of this, they are an excellent choice for monitor purchases. Dell also makes many great monitors and often has low prices with coupon deals. I highly recommend checking out Dell when you are looking for a new LCD monitor, especially a Dell branded one.

A Canadian outfit, NCIX also has a US branch. You may want to compare prices on both of its sites to find the best deal depending on the exchange rate. The appeal of NCIX comes from it’s offer of a 0-dead pixel replacement policy known as express coverage that you can purchase for a small fee in addition to your order. This ensures that you get a monitor with no pixel defects or up to 3 exchanges with no shipping costs. Ironically, the only LCD monitor I’ve purchased without any dead pixels was one I bought from them with the guarantee and no exchanges.

While I am generally not a fan of shopping for electronics offline or at Best Buy, you can’t argue with their return policy. You can return or exchange a monitor within 14 days. I once bought a 21.3″ LCD with several dead pixels and exchanged it at Best Buy. Your experience and degree of hassle may vary depending on the store, however.

Surprisingly, Newegg, perhaps the best online store for computer parts, is one of the worst places to buy an LCD monitor. In order to exchange, a unit must have 8 or more dead pixels, which is higher than many manufacturer policies! Buy or research your other computer parts here, but go elsewhere for LCD monitors.

Before buying an LCD monitor, always check the return/exchange policy of the seller as well as the manufacturer to see what the dead pixel policy is. For most retailers, they will likely default to the manufacturer’s policy. The ones I have used in the past with luck include those described above. Some retailers may have written policies but also have excellent customer service. Amazon, for example, has been known to accept returns under circumstances not adhering to their written policies in an effort to satisfy the customer. You should always tread with caution as your mileage may vary.

"Since LCD panel is made up of millions of micro electronic pixels, if one pixel no longer functions normally, it will become a bright or dark dot. By ISO 13406-2 standards, ASUS conforms to the acceptance level between 3 to 5 defective bright/dark pixels. In order to deliver ultimate vision experience to ASUS customer, if your panel is less than or equal to the above number of dots, then, it is considered as an acceptable LCD monitor.In addition, the Premium Range of ASUS LCDs offers a unique Zero Bright Dot (ZBD) warranty.Please refer to ASUS LCD Monitor Bright/Dark Dot Warranty Table below."

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.

Poking your screen may cause more pixels to die. I have only seen one person who damaged their LCD display that way when they grabbed the display part with their bare hands very hard while moving it around their desk. Its pretty obvious someone damaged the display that way too because as I remember, you get half-functioning pixels around the dead zones (no, not just getting some or one of the RGB components - you get gray distortion patterns of the pressure applied to the screen). Of course, you can do that to the screen and say it was shipping and handling problem.

Just as a warning if you decide to try to pull the dead pixel scam, I had a friend who kept on return flat panels because of too many dead pixels. Most of the dead pixels were dispersed across the screen with various color components. When he got his last screen, he had like 4 completely dead pixels right next to each other in the center of the screen and they wouldn"t replace it anymore. Now"s he stuck staring at a hole in the screen.

Have you tried different backgrounds of red, green, and blue (all colors should be set to maximum of one the RGB components, but leave the other two components at zero)? You might be able to find more dead pixels that way.

Also, you should checkout the contrast ratio with your preferred brightness setting. Some LCD panels may appear to washed out with gray blacks. Also the back lit may not be even and a completely dark screen may have uneven darkness or funny halos.

So you"ve just noticed that your monitor has a little black dot on it even when it"s turned on. Someone says that it"s a dead pixel, but what exactly does that mean, and why has it happened? First, we"ll explain exactly what a dead pixel is, so you know how to avoid them in the future.

A dead pixel is a name for a mechanical fault that can develop on TVs and monitors. For example, if you notice a small black dot on your TV or monitor screen, then you"ve found a dead pixel. This happens because power is no longer going to that pixel in question. As power is required for a pixel to show colors (even white), that pixel displays as black like it does when your display isn"t powered on at all.

A dead pixel on a brand-new display is a sign of manufacturer fault most of the time. In most cases, you can avoid these kinds of dead pixels by ensuring you"re buying a screen from a trusted brand. Cheap, low-quality displays are much more likely to have a dead pixel problem from the factory.

If your screen develops a dead pixel well after you bought it, it"s likely because of physical damage to the screen. If a display is hit or knocked, it can cause something to break internally that stops power from getting to a certain part of your screen. A good way to avoid dead pixels is to ensure that you"re always careful around your electronics and don"t accidentally hit the screen.

While it may only be small comfort, at least you know exactly what is going on with that small black dot on your display now. But, of course, knowing what a dead pixel is and knowing how to fix them are completely separate matters.
