You should only use this if you see a visible problem. Think of this as more the last resort. Screen Move shifts the screen a little at regular intervals to stop retention, and usually takes place when the TV has been left on for a long time. No need to change this setting. This feature automatically reduces the luminance brightness of static elements such as logos and subtitles.
If you spot any aspects of image retention on the screen, then you can manually start this process. A Pixel Refresh takes an hour to complete.
Other features to prevent the issue of burn-in are screensavers, which usually start after a few minutes of non-use. LG has a little exploding animation that jumps around the screen, while Sony displays a slideshow. Yes, image retention and burn-in are an issue in the sense that they can happen.
Each manufacturer includes a few self-cleaning technologies within their OLED displays to stop image retention from occurring, providing peace of mind for anyone looking to purchase an OLED TV. Of course, there are other TVs that are free from this problem, but they have their own advantages and disadvantages, too.

Image retention, also known as burn-in, can occur in all phosphor-based display systems including CRT television systems both direct view and projection as well as plasma display systems. Displaying the same still images for long periods should be avoided as permanent image retention or burn-in may occur. Recommended guidelines are as follows:. Do not display content in the aspect ratio black or gray bars on left and right side of content or letterbox content black bars above and below content for extended periods of time, or use either of these viewing modes repeatedly within a short period of time.
This plasma display system is equipped with multiple wide-screen viewing modes; use one of these screen modes to fill the entire screen with content. 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. It's also worth mentioning that most LCD TV warranties don't cover burn-in either and most don't mention it at all. The closest Samsung's warranty comes on its QLED TVs, for example, is to specifically exclude coverage of "brightness related to normal aging or any other issues if the TV is used for commercial or non-normal consumer use.
Samsung does not warrant uninterrupted or error-free operation of the product. It doesn't cover business use. 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.
The latest version only explicitly covers burn-in on phones. The fact is that if you do get burn-in on your OLED display, you're pretty much stuck with it. So your best bet is to avoid it altogether. But how? 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. Turning down the brightness controlled by "OLED Light" on LG's sets, and Brightness on Sonys will help, especially when you're watching the content that causes the image retention. Choosing a dimmer picture mode, like Cinema instead of Vivid, has the same effect. You'd only need to do this when watching something that causes image retention, like a video game for six hours every night, or hour cable news for 24 hours straight.
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.
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. In all cases the pixel refresher looks like a horizontal line that runs down the screen, for a period of an hour or more. It's designed to even the wear on pixels. Just like on LG's OLEDs, it's designed to remove image retention by scrolling a horizontal bar down the screen for an hour or so.
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. 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.
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. They stopped regularly updating the test in , 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. 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.
