will lcd monitors burn in in stock

One of the problems with old CRT monitors, over time, was a condition called burn-in. This phenomenon resulted in an imprint of an image onto the display that was permanent, caused by the continuous display of a particular picture on the screen for extended periods. A breakdown in phosphors on the CRT results in the image being burned into the screen, hence the term. Is there such a thing as LCD screen burn-in?

LCD monitors use a different method for producing the image on the screen and are immune to this burn-in effect. Rather than phosphors generating light and color, an LCD uses a white light behind the screen with polarizers and crystals to filter the light to specific colors. While LCDs are not susceptible to burn-in the same way CRT monitors are, LCDs suffer from what manufacturers call image persistence.

Like the burn-in on CRTs, image persistence on LCD monitors is caused by the continuous display of static graphics on the screen for extended periods. Long-term-static images prompt the LCD crystals to develop a memory for their location to generate the colors of that graphic. When a different color appears in that location, the color will be off and will display a faint image of what was previously displayed.

The persistence is the result of how the crystals in the display work. The crystals move from a position allowing all light through to one that doesn"t allow any. It"s almost like a shutter on a window. When the screen displays an image for an extremely long time, the crystals can switch to a particular position. It may shift a bit to alter the color, but not completely, resulting in a display other than the one intended.

This problem is most common for elements of the display that do not change. Items that are likely to generate a persistent image are the taskbar, desktop icons, and background images. These tend to be static in their location and displayed on the screen for an extended period. Once other graphics load over these locations, it might be possible to see a faint outline or image of the previous graphic.

In most cases, no. The crystals have a natural state and could shift depending on the amount of current used to generate the desired color. As long as these colors change periodically, the crystals at that pixel should fluctuate enough, so the image doesn"t imprint into the crystals permanently. However, if the screen is always on the image that doesn"t change, the crystals could obtain a permanent memory.

Set the screen to turn off after a few minutes of idle time. Turning off the monitor display prevents images from appearing for extended periods. Setting the monitor to do this when the computer is idle for 15 to 30 minutes can make a difference. These values appear in the Mac Energy Saver settings or Windows Power Management.

Rotate any background images on the desktop. Background images are a common cause of image persistence. By switching backgrounds every day or every few days, you"ll reduce the risk of persistence.

Using these items can prevent the image persistence problem from cropping up on a monitor. If the monitor displays image persistence problems, here are a few steps that can be used to correct it:

Use a screen saver with a rotating image and run it for an extended period. The rotating color palette should remove the persistent image. Still, it could take a while to remove it.

I remember in the old days of CRTs, my dad would warn me about dreaded "burn-in" on my computer screens and TVs. I know there was a big debate about plasma TVs and burn-in too, but is it still a problem? Does it affect LCDs? Do I need to care at all?

In general, burn-in isn"t nearly the problem it once was. However, you should still be aware of what it is and how to prevent it. Here"s what you need to know.

Burn-in is permanent, but it"s often confused with "image persistence," which is a temporary version of the same thing. Burn-in is most prominent in CRT and plasma screens, which use phosphors to create the image on your TV or monitor. However, it"s also possible to cause image persistence on an LCD-based screen, Photo by

CRTs and Older plasma TVs were quite susceptible to burn-in, but many modern TVs have features designed to lower the risk. Many contain a feature called "pixel shifting," for example, that shifts the image on your screen just enough so that the pixels are regularly changing, (but not so much that it"s noticeable to you). Some cheaper plasmas may be more susceptible, so this is an area where you get what you pay for.

If you do experience a little image persistence, it"s probably just temporary, and you can get rid of it with almost no effort. We"veRemove LCD image burn-in

The chances of getting permanent burn-in are pretty slim these days. You"d have to actually try to burn in your screen. With regular home use, you"re probably not watching the same persistent image for long enough. If you have a business that shows the same image on screen all day long, that might be a different story, but for most personal use, you shouldn"t have to worry. Photo by

Apart from the fact that it doesn"t feel like a "real" IPS panel (at certain angles part of the screen is dimmer), the screen somehow has a weird burn-in issue. After about 15-20 minutes of viewing a static image (like a PDF for example) and then switching to a dark image, I can already read bigger text on the area where the PDF was. In fact, while I was writing this I can already see the outline of this text box if I switch to a dark window (which is 100% opaque).

EDIT: I was on YouTube few minutes ago for maybe 15 minutes and I was able to take a picture of the burn-in afterwards. If you know the YouTube logo, you will easily recognize it and this was just a short time I had it on the screen while watching a video.

Expressly designed and tested for security and surveillance environments, AG Neovo’s patented Anti-Burn-in™ technology tackles the LCD monitor burn-in effect, otherwise known as a ghost image on the screen. Burn-in images result in the polarisation of the liquid crystal material contained within the TFT LCD panel. The Anti-Burn-in technology prolongs the lifetime of all AG Neovo monitors and displays featuring this technology to secure users’ investment.

LCD Burn-In, known as image sticking, image retention, image persistence, or ghost images, is the phenomenon where fixed images displayed on the monitor screen for extended periods cause the polarisation of the liquid crystal material contained within the LCD panel, making the image to be “burnt” on screen.

Burn-in on an LCD screen occurs because pixels permanently cannot return to their relaxed state after a static image is displayed on the screen over a long period of time. When a screen keeps displaying a single image, the crystals at those pixels will get a permanent memory, and thus the image on the screen will be imprinted onto them permanently. Once it causes screen burn-in, there is no recovery in most cases. Because of this, choosing a display or monitor allowing for pixel shift, like AG Neovo’s monitors with Anti-Burn-in, can help prevent LCD computer monitor burn-in.

“Image retention” and “Burn-in” are sometimes used interchangeably, but they are not precisely the same thing. Image retention, in most cases, is temporary and fixable. It appears when an image is temporarily “stuck” on the screen even if the content changes, but reversible by taking particular measures. Burn-in on the LCD screen is a form of image retention but is permanent and virtually impossible to fix. The prolonged use of static images would cause screen burn-in.

AG Neovo’s patented Anti-Burn-in™ technology tackles the LCD monitor burn-in effect, otherwise known as a ghost image on the screen. Burn-in images result in the polarization of the liquid crystal material contained within the TFT LCD panel. This technology prolongs the life of all AG Neovo monitors and displays to secure the user’s investment.

Anti-Burn-in technology is to activate the pixels to move by the designed time interval and protect panels from being seen the vaguely visible “residual image” under the static charge conditions so as to help prolong the lifetime of TFT LCD panels.

The patent on the Anti-Burn-in technology shows that AG Neovo places importance on its display quality to prevent image burn-in. To best fit the requirement of the security environment, Anti-Burn-in Technology is invented with high-level flexibility and effectiveness. There are three types of mode:

Execute faster than the Line and Dot Intervals. Frame Movement is to move the entire video frame horizontally and vertically (right/left/up/down) for a preset time interval.

Slower but more precise than the Frame Movement. Line Movement is to scan the screen starting from top to bottom and left to right with horizontal and vertical moving lines for a preset time interval.

The slowest but the most precise Anti-Burn-in mode. Dot Movement is to scan the screen with a set of “black & white” dots or pixels in left-to-right and top-to-bottom directions.

Unlike conventional displays, AG Neovo’s security and surveillance displays are built-in with Anti-Burn-in function to reduce the possibility of LCD burn-in for continuous security monitoring applications. It is not needed to create any screen saver, playback youtube video, or install additional tools to prevent burn-in effect.

Compared to the traditional LCD screen burn-in reduction tools which may cause evident interruption to the displayed images, AG Neovo’s patented Anti-Burn-in function is almost unnoticeable when applied. The specially designed three modes of Anti-Burn-in selection provide users with flexibility in choosing the optimal approach that best fits with their non-stop security monitoring.

Video surveillance is commonly used for monitoring of selected images to determine if an improper activity is occurring, such as theft, vandalism, and abnormal situations in daily operation, and any intervention is not allowed during the process. To ensure there are not any interruptions to the video monitoring, turning on a screen saver, reducing contrast/brightness or playing white static image for a particular while is not an option. Instead, selecting a security monitor with built-in Anti-Burn-in function is an efficient solution.

Burn-in on the screen is technically hard to fix. Instead, here are some tips on how to remove image persistence on LCD screens and prevent permanent effects:

Enable the “Pixel Shifting” function on your monitor or display. Most of AG Neovo monitors have a built-in Anti-Burn-in, which allows varying pixel usage by activating the pixel to move at regular intervals. If not enabled automatically, you can manually turn it on and try to alleviate any image retention problems.

Reduce screen contrast and brightness. Lower contrast allows even lighting levels across the LCD screen and thus has less strain on a specific area of the screen. Then, try to watch some different contents, and the effect of Image retention might go away on its own.

Turn on white static image for approximately as long as the persistent image was displayed; this is to use a completely white screen to overwrite the burn-in image. Or, create a screen saver that alternates between black and white images. The continuous changing of white/black across your screen can help alleviate the ghost image from the screen. The solid colour background might reset the image burn but is more likely to deal with image retention than image burn-in.

Have you ever left your TV or monitor on for days, stuck on the same image? You return to your screen, only to find an image burned into the display. No matter what you do, it won"t go away. It is a permanent image burn.

Why do monitors and TVs get image burn? Why can"t manufacturers prevent LCDs and plasma screens from a burnt image imprint? Moreover, what can you do to fix an image burn?

In some cases, you can minimize the image burn effect. In others, you can remove the image burn completely, so long as it hasn"t been burning too long.

Before flat-screens and crystal displays, most TVs and monitors featured CRT (Cathode Ray Tube) technology. In CRTs, individual pixels comprise a red, blue, and green phosphor component. Depending on the intensity of each phosphor component, the pixel appears to the human eye as a unique color.

When a particular still image remains for too long, the intensity of each phosphor component diminishes at an uneven rate. The result is a ghost image on the screen, which is known as image burning.

Plasma displays use plasma, a gaseous substance containing free-flowing ions. When the plasma is not in use, the particles in the plasma are uncharged and display nothing. With the introduction of an electric current, the ions become charged and begin colliding, releasing photons of light.

This is a very simplified version of how a plasma screen works. However, the main thing to understand is that plasma screens use phosphor material (like CRTs) to turn those photons into images.

LCD and LED do not work in the same way as CRTs, either. LCD and LED screens use backlit liquid crystals to display colors. Although manufacturers market screens using LED and LCD, an LED screen is still a type of LCD. The white backlight filters through the liquid crystals, which extract particular colors per pixel.

LCD and LED displays don"t suffer from the same type of image burn as CRTs and plasma screens. They"re not completely clear, though. LCD and LED screens suffer from image persistence. Read on to find out more about image persistence.

Before you can fix screen burn-in, take a second to understand why these images burn in the first place. LCDs and LEDs don"t suffer from burn-in as seriously as plasma screens. But static images can leave an imprint on both display types if left alone for too long. So, why does image burn happen?

First, let"s tackle plasma screen burn-in. Remember why CRTs experience image burn? When a still image remains on the screen for too long, the phosphor components in each pixel wear out at different rates. The uneven burn rates leave behind a ghost image, forever etched into the screen.

Plasma screens also suffer from phosphor deterioration. Plasma burning occurs when pixels on the screen are damaged through long exposure. The phosphor loses its intensity and only shows the light it was fed repeatedly. In this case, the still image, which causes the burn.

LCD and LED screens can also experience image burn, though the image burn process can take longer to develop into a permanent issue. In addition, LCD and LED screens suffer from another issue, known as image retention (also known as image persistence or an LCD shadow).

Image retention is a temporary issue that you are more likely to notice before it becomes a permanent issue. However, proper image burn can still affect LCD, LED, and OLED screens.

Image retention is a different issue from image burn (although it is a precursor to image burn). For example, you"re using an image of a steam train as a reference point for a drawing. You have the steam train image on your screen for a few hours before you decide to play a video game instead.

When you load up the video game on the screen, you can still see the faint outline of the steam train on the screen. The steam train image will remain for a short while, but the movement and color changes of the video game (or film, TV show, or other media type) should erase the retained image.

The other thing to consider is that LED and OLED image burn-in, when it happens, is irreversible. That"s because of how LED and OLED screens work. Individual pixels within an LED display decay when they emit light.

Under normal use, an LED, OLED, or QLED screen won"t suffer image burn. However, if you leave your screen on a single channel for hours every day, then burn-in can become an issue, as it would with almost any screen.

Issues arise when a screen shows a single news channel 24 hours a day, every day, causing channel logos to burn-in, along with the outline of the scrolling news ticker and so on. News channels are a well-known source of television burn-in, no matter the screen type.

Image burn-in fixes exist for LCD and plasma screens. How effective an image burn-in fix is depends on the screen damage. Depending on the length and severity of the image burn, some displays may have permanent damage.

The best fix for screen burn is to prevent it in the first place. Okay, that isn"t super useful if your screen is already experiencing image burn. However, you should always try not to leave your screen on a still image for too long. The time it takes for an image to burn-in varies from screen to screen, between manufacturers, sizes, and panel type.

My personal rule of thumb is to turn off the display if I plan on being away for more than 15 minutes. That way, it is difficult to get caught out, plus you save yourself money on electricity costs and monitor or TV wear and tear.

Another prevention method is to reduce screen contrast as much as you can. Unfortunately, most screens aren"t calibrated correctly, often pushing the contrast and brightness settings too high.

Lower contrast means the lighting across your screen is more even. This means less strain on specific areas of the screen, which helps protect against image burning.

If your plasma or LCD screen already has image burn-in, you can try turning on white static for 12 to 24 hours. The constant moving of white-and-black across your screen in random patterns can help remove the ghost image from your screen.

Unfortunately, this won"t work for extreme cases. Some TVs will have a built-in pattern swiping option that basically accomplishes the same thing (filling your screen with random patterns).

Pixel-shift constantly slightly adjusts the image on your screen, which varies the pixel usage to counteract image burn. You might have to enable a pixel or screen shift option in your screen settings. Pixel-shift is a handy feature for LED and OLED screens that cannot recover from image burn and should help counteract an LCD shadow.

Other modern screens feature built-in screen refresh functions that the manufacturer will advise using to remove image retention and image burn issues.

The best tool for fixing ghost images is JScreenFix. The original program helps fix monitors with dead pixels, but the same company also released an "advanced" version of the tool, known as JScreenFix Deluxe.

While the Deluxe version uses advanced algorithms to repair burned screens and prolong plasma and LCD longevity, the official site is no longer up and running, and there is no way to download the full version officially.

You can find the free version of the Deluxe app online, but it is limited to 20 minutes running at a time. Furthermore, we"re not going to link out to the versions you can find online as we cannot verify the security of these installations. If you do use the Deluxe version, you do so at your own risk.

Another option is to set a completely white desktop background and leaving to run for a few hours. The solid color might reset the image burn. A solid color background is more likely to help with image persistence than image burn, but it is still worth trying.

If you have television burn-in, you can attach a laptop to your TV using an HDMI cable, extend your desktop to the television, and share the white screensaver. Hopefully, that will shift your television burn-in.

The team over at ScreenBurnFixer offers a few different ways you can attempt to fix screen burn on your TV or monitor. As with any other screen burn-in fixes, their chance of working depends on the scale of the issue.

You can head to the ScreenBurnFixer Video page and find a video that matches your screen type, then let the video play for as long as possible (we"re talking multiple hours, not a quick half an hour blast). Alternatively, head to the Chart page and find your device or a device that matches your specifications.

There are several ways you can attempt to fix screen burn-in. The results will vary between the screen type and the level of burn-in. A screen with extensive image burn may not clear entirely, although you might see an improvement.

Some screen degradation over time is understandable. However, if you follow the steps in this guide, you"ll protect your screen from image burn before it becomes a permanent issue.

LCD and OLED monitors are most vulnerable to screen burn when new, so you may want to avoid leaving the same image up for too long during the first 100 hours of use

Image retention on a phone display or computer monitor is mostly an issue for devices that display static content or are used for video gameplay with a heads-up display. Unlike with old CRT devices where the phosphor compounds would degrade over time, the “permanent” stationary object or remnant of a picture on an LCD monitor is usually a form of transient image persistence. Here’s how you can fix it and get your high-performing computer monitor back up and running.

While screen burn and image retention are often used interchangeably they’re not quite the same thing. Image retention is a temporary “ghost image” that you can usually get rid of, while “screen burn” means some of the screen’s pixels are “burned out” and it is more difficult to fix, typically requiring hardware repairs, as it’s a more complicated monitor display problem to repair. Obviously it’s not the most convenient problem to have, especially if it’s happening on your best 32-inch gaming monitor, but there are ways to test it, mitigate it, and potentially resolve it

OLED screens are the favored choice for new smartphones and high-resolution TVs, but this type of screen is more susceptible to image retention than LCD screens. Irregular pixel usage can cause noticeable discoloration over a long period of time, typically of static elements like navigation buttons or news station logos. That said, screen burn-in is preventable and for most users should not deter the purchase of a new OLED monitor.

The reason for OLED screens’ being more vulnerable to screen burn-in has to do with the different lifespans and energy demands of different colored pixels. Blue pixels use more energy and tend to wear out faster, which contributes to the ghosting effect of burned-in images. Still, ghost images are generally only an issue for use cases involving static image elements displayed at full brightness for a long time. Also, double-check your warranty and/or computer insurance if you can get professional help for fixing image retention. You might even have coverage through your property insurance, and we have guides on explaining if, for example, your homeowners insurance can cover a computer.

If you’re not sure whether you have screen burn on your device, you can run a screen burn test. Several apps for Android and iOS devices help test for screen burn. Typically this involves displaying one primary color at a time at varying brightness on the device’s LCD screen.

These tips should help get rid of ghost images caused by image retention on modern LCD screens and OLED devices like smartphones, tablets, TVs, and laptops. Image persistence on LCD displays is generally more fixable than “burn-in” on a CRT monitor or AMOLED screen.

Sometimes you can fix a seemingly permanent ghost-like image on an LCD by turning the device off and then turning it back on again after several hours. Try colorful video content or fast-paced videos, or any varied content.

Setting the display brightness to a lower level or enabling auto-brightness if so equipped may reduce the appearance of screen burn or image retention.

Depending on the display technology, you can sometimes fix stuck pixels on a monitor by changing display & brightness settings, choosing dynamic screensavers or adjusting preset picture displays, and turning on auto-brightness. Some software fixes are also available. These typically involve displaying one solid color at a time, which may help get rid of image retention. You may also want to check for “dirty screen effect” and make appropriate adjustments.

On some devices, you can download apps that aim to fix image retention and help reduce the risk of burn-in. To address image persistence on an Android Phone, you can find apps on the Google Play Store that adjust display timeout, play dynamic, all black or moving screensaver images, and even test for burn-in using a white image.

Likewise, for an iPhone, you can visit the App Store for apps that help check your phone for burn-in problems and protect your phone from developing annoying image burn.

On most smart TVs there are some settings you can utilize to reduce the appearance of image retention. LG offers an option called Screen Shift for its OLED TV models, similar to Sony’s Pixel Shift technology, which shifts the image very slightly so as to minimize wear on individual pixels.

In extreme cases where you have dead blocks of pixels or significant degradation of image quality, you may want to opt for display device replacement to remedy screen burn.

There are some easy techniques you can use to help prevent screen burn-in from happening in the first place. The following tips should work on most OLED and LCD screen devices including Android smartphones and tablets, iOS devices, and laptop computers.

Manufacturers recommend keeping brightness at 50% or lower on screens that will be used to display a non-moving picture for more than a few hours at a time.

On August 31, 2017, we started a long-term 20/7 burn-in test on 3 TVs (OLED vs VA vs IPS). Our goal was to see how their performance changed over time, especially with static images like network logos, black bars in movies, or video games with a fixed interface.

We already test for temporary image retention, which generally subsides over a few minutes. It"s a temporary annoyance and results in some faint artifacts usually visible in high contrast areas.

Permanent image retention is a more serious issue, but it requires looking at the TV"s performance over months or years. We tested three TVs side-by-side, the OLED LG B6, the VA Samsung KU6300, and the IPS LG UJ6300 in a two-year-long test.

This test ended in 2019, as we feel that we now have a good understanding of what types of content are likely to cause burn-in. However, we still haven"t addressed the issue of longevity in general, and we don"t know if newer OLED panels are still as likely to experience burn-in. To that end, we"ve decided to start a new accelerated longevity test to better understand how long new TVs should last and what are the most common points of failure. Although burn-in isn"t the main goal of this test, we"re hoping to better understand how newer OLED panels compare to the older generation of OLEDs. It"s generally accepted that burn-in isn"t as much of an issue as it used to be, but it"s unclear just how much better the newer OLED TVs are. With new panels, new heatsinks, and even brand-new panel types like QD-OLED, there are a lot of unknowns.

The 20/7 burn-in test ran for about two years, from August 31, 2017, until November 15, 2019. The goal of this test was to see whether burn-in could happen for the three most popular TV types (VA LCD, IPS LCD, and OLED). These are the results of our experiment:

Long periods of static content will cause burn-in on OLED TVs. The red sub-pixel appears to degrade the fastest, followed by green and blue. The effect is cumulative, as even cycled logos do burn-in (but over a longer period). We investigated this further in our Real Life OLED Burn-in Test.

Black letterbox bars were displayed for almost 5,000 hours (equivalent to 208 days of continuous letterboxing). Some letterboxing is starting to become noticeable on full-screen slides, but not in normal content. As a result, we don"t expect letterbox bars to cause any issues for people. It"s due to the uneven aging of the screen. The black portions of the screen haven"t aged as much as the rest, so those dark areas appear brighter in regular content.

Some of the LED backlights of the UJ6300 died, so the image is unwatchable. To keep a constant brightness of 175 nits across these TVs, the UJ6300"s backlight was turned up to maximum, while the other TVs achieved this brightness at a lower backlight/OLED Light setting. It may mean that it has been operating at a higher temperature, contributing to the failure.

The TVs were placed side-by-side in one of our testing rooms, as shown to the right. The TVs stayed on for 20 hours a day, seven days per week, running our test pattern in a loop. They were turned off for 4 hours each day using USB infrared transmitters connected to each TV and controlled by a PC to better represent normal (but still very heavy) usage. On the B6, the "Pixel Shift" option is enabled. A single Android TV Box was used as a source, with an HDMI splitter used to provide the same material to each display.

We used our calibration settings, as shown on the review page below, but with the backlight adjusted to reach 175 nits on our checkerboard pattern and no white balance settings applied.

A 5.5-hour video loop was used as the test pattern. It was designed to mix static content with moving images to represent typical content. The base material is a recording of over-the-air antenna TV with an overlay of RTINGS logos of different opacities and durations and added letterbox black bars. These additional elements are:

Ever notice a partial discoloration of text or image across the screen of your monitor? This can be annoying, especially when the monitor is an industrial display used to help your business.

These unpleasant discolorations are known as screen burn-in. In this blog post, we will discuss how to prevent and recover from LCD monitor screen burn-in.

LCD display burn-in, also known as ghost image or image sticking, is the retention of the previous image on the screen even after you’ve swiped the screen. LCD burn-in happens on an LCD screen when pixels cannot return to their relaxed condition after a static image shows on the screen for an extended period.

Technically, these are two different things. Image retention occurs when your display swiftly shifts from one image to another. For example, image retention occurs when you briefly notice the “shadow” of the first image in the second.

LCD monitor screen burn-in is the permanent version of image retention. Screen burn-in occurs when an image is shown on a screen for so long that it may still be seen after the screen is off. LCD burn-in happens when some sub-pixels have remained so brilliant for a very long time that they are unable to go back to their initial state. They always produce a “ghost” image because they are inherently “stuck” in a non-neutral state.

When pixels stay in the same place for an excessively long time before switching to another position for a brief period, this can lead to LCD monitor burn-in. In addition, when an image is displayed on a screen excessively, the liquid crystal material in the LCD panel becomes polarized. As a result, it develops into a permanent discoloration known as LCD display burn-in.

Image persistence on LCD screens is avoidable and can be corrected. There are several ways to prevent or repair screen burn-in in LCD monitors, which include the following:

Nauticomp Inc. is dedicated to providing superior customer service through product innovation, quality, and customer support. Our entire line of high-performance rugged displays is at the forefront of leading-edge display technology.

In the TV world, LG has a page that says "It is rare for an average TV consumer to create an environment that could result in burn-in." Nonetheless, stories of OLED burn-in don"t seem rare online, with owners on YouTube, forums and social media reporting the issue. Reviews site RTings has demonstrated burn-in on LG OLED TVs in long-term tests.

So if the fear of the mere possibility of burn-in is your primary concern, the decision is simple: Buy an LCD-based display instead. But know that you"re sacrificing the best picture quality that money can buy. Here are some points to keep in mind:

All things considered, burn-in shouldn"t be a problem for most people. That"s why we at CNET continue to recommend OLED-based TVs, phones and other devices in our reviews. From all of the evidence we"ve seen, burn-in is typically caused by leaving a single, static image element, like a channel logo, onscreen for a very long time, repeatedly.

If you, like most people, watch a variety of content on your TV, phone, or other device with an OLED screen, you"re not going to need to worry about burn-in.

What can you do to prevent burn-in on that new TV? As we mentioned, vary what you watch a bit. In particular, don"t watch something that has the same static areas displayed onscreen, nonstop for days on end.

The logos and news tickers on cable news channels are examples of those static areas -- they have elements that never move, and they remain on screen the entire time you"re watching. That means if you leave your TV running Fox News, CNN, MSNBC or ESPN all day long and don"t watch enough other programming, you"re more likely to get burn-in. Or at least, image retention, which we"ll discuss in a moment. If you play the same game for 8 hours a day, every day, the onscreen status display or HUD is also a likely culprit for burn-in.

To repeat, you can watch those channels, play games or whatever else to use your TV as a TV, your phone as a phone, etc. You just shouldn"t watch only those channels, all day every day. And if that sounds extreme, know that emails I"ve gotten from readers about burn-in always have some variation on "well I only watched that channel for 5 hours a day." If that sounds like you, get an LCD.

As long as you vary what"s displayed, chances are you"ll never experience burn-in. That varied content will age your screen evenly. So in a 24-hour period you watch a movie, play some games, binge some TV shows, they"re all varied enough that you should be fine.

The RTings torture test we mentioned above lasted the equivalent of 5 years of use and they still say "Our stance remains the same, we don"t expect most people who watch varied content without static areas to experience burn-in issues with an OLED TV."

We"ve designed the OLED screen to aim for longevity as much as possible, but OLED displays can experience image retention if subjected to static visuals over a long period of time. However, users can take preventative measures to preserve the screen [by] utilizing features included in the Nintendo Switch systems by default, such as auto-brightness function to prevent the screen from getting too bright, and the auto-sleep function to go into "auto sleep" mode after short periods of time.

Which is to say, Nintendo is fully aware of this potential and took steps to minimize the risk. Also, despite many games having static HUDs, you"d need to play just that one game, for hours upon hours, every day without ever using the screen for anything else, at the highest brightness settings.

Let"s get the descriptions right. Though often used interchangeably, "image retention" and "burn-in" are not the same thing.Image retention is temporary: It goes away in time.

Image retention occurs when parts of an image temporarily "stick" on the screen after that image is gone. Let"s say for an hour you"re looking at a still picture of a white puppy (hey, you do you, we won"t judge). Then you decide to watch a movie. Let"s say Best in Show because you"re keeping with your theme. But as you"re watching you can still see the white puppy image, as if it"s a ghost on the screen, staring at your soul.

You"re not crazy, probably. That"s just an extreme case of image retention. Chances are it will go away on its own as you watch stuff that isn"t the same still image of the puppy.Here"s a section of a 2018 LG C8 OLED TV screen displaying a gray test pattern after 5 hours watching CNN on the brightest (Vivid) mode. They"re the same image, but we"ve circled the section with the logo on the right to highlight it. To see it better, turn up the brightness. In person, it"s more visible in a dark room, but much less visible with moving images as opposed to a test pattern. Since it disappeared after running LG"s Pixel Refresher (see below), this is an example of image retention and not burn-in.Sarah Tew/CNET

Now imagine you leave your TV on for days or weeks instead of hours, showing the same image the whole time. Then you might be in trouble. With image retention, usually just watching something else for a while will make the ghost image disappear. With burn-in, it"s going to remain there for a while. Maybe not forever, but perhaps longer than you"d want.

This is an extreme case, largely just to illustrate what happens. In reality, it"s going to be far more subtle. Watch a lot of the same TV news station, like CNN in the example above? Not sure how your heart can handle that, but let"s say you do. That station"s identifying logo is a prime candidate for image retention and eventually burn-in. Ditto the horizontal borders of the "crawl" on the bottom of the screen.

If you play the same video game for hours and days on end, that game"s persistent scoreboard or heads-up display might burn in. Basically, anything that stays on screen for a long time and doesn"t change can cause image retention and perhaps, eventually, burn-in.

Apple, for one, flags users of OLED-screened iPhones, like the X, 11 and 12, that burn-in is a possibility. Here"s the quote from its support page for the products:With extended long-term use, OLED displays can also show slight visual changes. This is also expected behavior and can include "image persistence" or "burn-in," where the display shows a faint remnant of an image even after a new image appears on the screen. This can occur in more extreme cases such as when the same high contrast image is continuously displayed for prolonged periods of time. We"ve engineered the Super Retina and Super Retina XDR displays to be the best in the industry in reducing the effects of OLED "burn-in."

What"s colloquially called "burn-in" is actually, with OLED, uneven aging. They don"t "burn in" as much as they "burn down." The candle that burns twice as bright burns half as long, right? OLED pixels very, very slowly get dimmer as they"re used. In most cases this isn"t an issue since you"re watching varied content and all the pixels, on average, get used the same amount. But if you"re only watching one thing, that one thing could cause uneven wear. Visually, and in the vernacular, this wear is called "burn-in." Uneven wear is more accurate, but also a lot more syllables.

Also, OLED technology has gotten better. Billions of dollars have been spent on OLED manufacturing and R&D, and that"s ongoing. So stories you may have heard about "burn-in" likely entered the zeitgeist years ago about older OLED displays. You just don"t hear about newer OLEDs having these issues except in extreme situations like those discussed above. You"d likely hear a LOT more stories about OLED now that the two largest phone manufacturers, and many smaller ones, use OLEDs in millions of phones and have for years.

In their warranties, LG and Sony explicitly state that image retention and burn-in are not covered on their OLED TVs. When CNET reached out to LG a couple to ask why, a representative replied:

"There is generally no warranty coverage for image retention by TV companies and display manufacturers. Image retention may result when consumers are out of normal viewing conditions, and most manufacturers do not support warranty for such usage regardless of the type of display," said Tim Alessi, director of new products at LG.

Sony"s reply was similar: "Our warranty covers product and manufacturing defects. Burn-in is not covered as it is caused by consumer usage and is not a product defect."

Neither the iPhone warranty nor AppleCare explicitly mention burn-in, but neither apply to "normal wear and tear," and Apple"s support page above makes clear that it considers burn-in "expected."

When CNET reached out to Samsung for details, the representative defined "normal consumer use" as "use of the product by consumers in a home environment for viewing content and/or gaming in a typical manner. It doesn"t cover business use." In other words, those ESPN logos you see burned into the screens at your local sports bar would not be covered.

Extended warranties don"t typically cover burn-in either. One of the most common, SquareTrade, is available from Amazon, Walmart, and others. They explicitly don"t cover burn-in. However, Best Buy"s Geek Squad Protection Plan might, depending on when you bought it. The latest version only explicitly covers burn-in on phones.

"To avoid the possibility of burn-in, consumers should avoid leaving static images on an OLED screen for long periods of time. For example, leaving a video game paused onscreen for several hours or days," a Sony spokesperson said.

If you notice image retention, don"t panic. Chances are if you watch something different, it will go away on its own after a while. If you"re repeatedly getting image retention of the same thing, then that could be cause for concern.

Pretty much all OLED TVs also have user settings to minimize the chance of uneven wear or burn-in. One is called something like "Screen Shift" (on LGs) or "Pixel Shift" (on Sonys), which moves the image slightly around the screen. They also have built-in screensavers that pop up after extended idle time. You should also enable screen savers on connected devices like game consoles and streamers.

To remove image retention, the TVs can also perform "refreshers" on a daily or longer-term basis. On Sony TVs the feature is called "Panel Refresh," and LG calls it "Pixel Refresher." It can be run manually if you notice image retention or, in the case of LG, you"ll get a reminder to run it after 2,000 hours.

LG also has a Daily Pixel Refresher, which it says "automatically operates when users turn off the TV after watching it for more than four hours in total. For example, if a user watched TV for two hours yesterday and three hours today (more than four hours in total), when powered off the Daily Pixel Refresher will automatically run, deal with potential image retention issues, and reset the operation time. This process will occur when the TV is powered off after every four hours of cumulative use, even if it"s in one sitting."

When it comes to phones I wouldn"t be too concerned, since it"s likely you"ll replace the phone far sooner than any image retention/burn-in issues become bothersome. Regarding my aforementioned S6 Edge, even though I noticed it, I wouldn"t say the burn-in reduced my enjoyment of the phone. I was never watching a video and thinking, "Wow, I can"t enjoy this video because of the burn-in." Since the phone was in use by its second owner twice as long as I had it, and was only let down by its battery, burn-in clearly wasn"t a dealbreaker. My friend replaced it with a Pixel 4a, which also has an OLED screen. So even after 4 years with that screen he still preferred to get a phone with OLED.

With TVs, beyond the methods outlined above, there"s not much you can do to reverse burn-in. In theory, I suppose, you could create an inverse image using Photoshop and run that on your screen for a while. This could age the rest of the panel to more evenly match the "burned in" area. Figuring out how to do this is well beyond the scope of this article, and you"d need to be pretty well versed in Photoshop to even attempt it.

CNET has not conducted any long-term real-world tests of OLED burn-in. In our experience reviewing TVs, we have seen image retention on OLEDs that disappeared quickly, for example after running a series of static test patterns, but nothing permanent.

The most comprehensive independent tests for burn-in on TVs was run by the aforementioned review site RTings. In August 2017 they began a burn-in torture test with LCD and OLED TVs, followed by a "real life" torture test in 2018. They stopped regularly updating the test in 2020, but that was after the equivalent of 5 years of normal use on multiple TVs, and still they felt that most people will never have an issue with burn-in.

Before you check it out, keep in mind what they"re doing is not normal use. You"d have to be trying to wreck a TV to make it look that bad, which is literally what they"re trying to do. That said, the information is still valuable, and the main takeaway is that OLED is indeed more susceptible to burn-in than LCD.

You"ve noticed a ghostly image on your TV or phone screen. If it goes away after a few minutes of watching something else, it"s image retention and it"s probably nothing to worry about. If it "sticks" longer, or you"re repeatedly seeing that same residual image, it"s burn-in. With phones, you"ll likely replace it before the screen becomes an issue.

With OLED TVs, it"s something to keep in mind if you"re a TV news junkie, or only ever play one video game. Keep an eye out for image retention or uneven wear. If you spot it, perhaps switch up your viewing habits, adjust the TV"s settings, or run the pixel refresher a few times. And if you watch content with hours of the same static image each day, or just keep CNN, Fox or CNBC on in the background all day, you should probably get an LCD TV.

If you vary your TV viewing habits like most people, however, it won"t be an issue. Even so, caveat emptor. Or as Caesar himself once said, "Conscientiam autem ardeat sed non anxius" (be aware of burn-in, but not concerned). He was, we hear, a big iPhone fan.

You can follow his exploits on Instagram and his travel video series on YouTube. He also wrote a bestselling sci-fi novel about city-size submarines, along with a sequel.

To begin, it"s critical to understand the nature of the problem. A screen burn-in is a display phenomena in which a portion of the display becomes permanently discolored as a result of extended use of a static image. It"s also worth noting that OLED displays are significantly more prone to screen burn-in than LCD panels. In truth, what most people mistake for screen burn-in on an LCD panel is frequently a different problem.

This app will display many colors in a randomized fashion to overcome the burnt pixels. It"s mostly effective on Amoled displays and might also help with LCD displays too.

Manufacturers of plasma and LCD flat panel televisions are continuously introducing technology to help reduce the likelihood of this problem, but there are simple steps you can take to help reduce the chances of experiencing image "burn-in.

For new plasma TVs in particular, be wary of leaving images on the screen for long periods. When phosphors are fresh, they burn more intensely as they are ignited. This means that relatively new plasma TVs are prone to "ghosting", which occurs when on-screen images appear on the screen for an extended time.

If you are using your TV to display a video game from a computer, make sure to utilize screen saver features or power management settings that can change or turn off the display after a period of time.

"Stuck" images can be removed by "exercising" the LCD pixels to bleed off the residual capacitive charge. This can most easily be accomplished by using a random pattern screen saver that changes the screen image repeatedly. You should be able to connect your LCD TV to a computer with TV-out capability. The time required to clear the stuck image can vary widely (minutes, hours, days) depending on the panel technology and the severity of the stuck image.

Turning the LCD monitor off for an extended period of time does not clear the image. The charge must be bled off by charging/discharging the pixels with random images.

Contrary to popular belief, LCDs do suffer from permanent burn-in. If memory serves me well, what causes it is low-level UV generated by the backlight slowly degrading polarizers in bright areas. It is a very slow process, I"ve only seen burn-in on screens displaying a static image 24/7/365 for several years in an industrial setting or in PoS devices. It"s purely an aesthetic drawback and a fairly rare one, usually the backlight fails before burn-in becomes visible. If a device works, the screen burn-in won"t cause it to fail. If it bothers you and you"re feeling adventurous, you can try to find the screen"s OEM part number and replace it, but it"s perfectly safe to leave as is.

OLED displays have higher contrast ratios (1 million : 1 static compared with 1,000 : 1 for LCD screens), deeper blacks and lower power consumption compared with LCD displays. They also have greater color accuracy. However, they are more expensive, and blue OLEDs have a shorter lifetime.

OLED displays offer a much better viewing angle. In contrast, viewing angle is limited with LCD displays. And even inside the supported viewing angle, the quality of the picture on an LCD screen is not consistent; it varies in brightness, contrast, saturation and hue by variations in posture of the viewer.

There are no geographical constraints with OLED screens. LCD screens, on the other hand, lose contrast in high temperature environments, and lose brightness and speed in low temperature environments.

Blue OLEDs degrade more rapidly than the materials that produce other colors. Because of this, the manufacturers of these displays often compensate by calibrating the colors in a way that oversaturates the them and adds a bluish tint to the screen.

With current technology, OLED displays use more energy than backlit LCDs when displaying light colors. While OLED displays have deeper blacks compared with backlit LCD displays, they have dimmer whites.

LCDs use liquid crystals that twist and untwist in response to an electric charge and are lit by a backlight. When a current runs through them, they untwist to let through a specific amount of light. They are then paired with color filters to create the display.

AMOLED (Active-Matrix Organic Light-Emitting Diode) is a different form of OLED used in some mobile phones, media players and digital cameras. It offers higher refresh rates with OLEDs and consume a lot less power, making them good for portable electronics. However, they are difficult to view in direct sunlight. Products with AMOLED screens include Galaxy Nexus, Galaxy S II, HTC Legend and PlayStation Vita.

Image burn-in, also referenced as screen burn-in or ghost image, is a permanent discoloration of sections on an electronic display caused by increasing, non-uniform use of the screen.

The term burn-in dates back to when old monitors using phosphor compounds that emit light to produce images lost their luminance due to severe usage in specific display areas.

Chances are you"ve encountered image burn-in and image retention before, but you didn"t know which one you were seeing. They both have the same visual effects, so it"s easy to mistake them for each other, but there"s one key difference:

Most of the time, these guides explain how image retention works and how you can speed up its recovery process. We want to clear up any confusion you might have about image burn-in and image retention on LCD and OLED displays.

Image retention, also known as ghosting or image persistence, is the temporary effect of images remaining visible on LCDs or OLEDs for a short period, usually a few seconds.

If the images fade away after a short time, you are dealing with temporary image retention. If the images stay permanently, you are dealing with image burn-in.

Image retention doesn"t require any intervention from the user to make it go away – it"ll do that by itself. Retention will often occur before burn-in does on newer display technology like our

using a screen saver, cycling various graphics on the screen to exercise the pixels, and powering off the display whenever possible will help clear the image retention on your display.

These are the same tricks you"ll see advertised as a "cure" for image burn-in, but don"t be fooled. There"s no fix for burn-in, only ways to prolong it from happening.

Before you assume your screen has burn-in damage, try these tips and wait to see if it"s just image retention. Image retention is a harmless and common occurrence on many screens.

Image burn-in is caused by screen pixels that stay activated in a static position for long periods of time.Think of a TV in a lobby or waiting area that"s always playing the same news channel. The news channel footer and logo get burned into the screen permanently, even when you change the channel.

When LCD or OLED pixels stay activated in a static position, they"ll eventually become "stuck" in that position. When this happens, you"ll notice a faded, stubborn image that persists on the screen.

After showing a static image for long periods of time, the crystals in a liquid crystal display become weaker to move, and have more difficulty turning from the fully "ON" position to the fully "OFF" position

When pixels fail to activate or deactivate entirely, it results in faded images that won"t clear from the screen. This is common in applications using character LCDs where the alphanumeric characters are updated less frequently.

OLEDs are unique because they don"t need a backlight to light up. Each pixel on the display is a self-illuminating LED, so they generate their own light. However, the pixels inevitably lose their brightness over time. The longer an OLED pixel is illuminated, the dimmer it will appear next to lesser-used pixels.

If a static image stays on an OLED display long enough, the pixels will leave a shadow behind the previous image, even when the display shows something completely different.

Remember: There"s no way to remove or reduce burn-in after it occurs. If a stubborn image persists for extended periods or after restarting your display, you"re likely dealing with image burn-in.

Even the most advanced displays will experience burn-in at some point, but there are some simple actions you can take to extend your screen"s lifespan before burn-in occurs. With the proper practices, you can get years of outstanding performance from your display without any burn-in effects.

If a power cycle isn"t an option, you can use the display ON/OFF command to turn off the display. Alternatively, you can put the display into sleep mode while retaining the display data in RAM.

A screensaver is a good alternative if you can"t turn your display off. For displays that don"t need to be ON at all times, it"s helpful to let the screen rest when not in use.

Get those pixels moving! The longer a pixel stays activated in a static position, the closer it gets to being burned in. You can exercise your screen"s pixels with scrolling text, moving images, or changing colors.

For an OLED display, decreasing the contrast will lower the brightness and reduce the rate of image burn. More illumination (brightness) requires more current, which reduces OLED pixel lifespans.

For a LCD display, lowering the contrast will put less stress on the liquid crystals and will help to reduce the rate of pixels becoming weak, or sticking.

Remember that image burn-in is not reversible and can not be fixed once it happens. Whether it is a scrolling effect, rotating pixels, using a screensaver, or turning off the screen when not in use, it"s essential to establish image burn-in preventive measures to help extend the lifespan of your display.
