Image retention is a previous picture that remains visible after the content changes; it may fade. OLED burn-in is persistent, uneven pixel wear that remains visible over other content. Both can look like a ghost image, but permanence is the practical dividing line. Repeatedly displaying bright, fixed elements—such as channel logos, news tickers, menus, clocks or game HUDs—in the same locations is the main avoidable risk.
Image retention and burn-in are related, but permanence separates them
Image retention
Image retention describes a visible afterimage left by earlier content. You might see the outline of a menu, logo or scoreboard after switching to a different picture. Temporary retention can diminish after varied content is displayed, after the panel cools, or after the television runs its normal compensation cycle.
Burn-in
Burn-in is the longer-lasting form of retention. Unevenly worn pixels produce a pattern that remains visible across other programs, games and menus for a long time. LG USA Support describes it this way: “Burn-in is a form of image retention that lasts much longer, and it’s usually visible even when playing other content.” The wording appears in its June 26, 2026 troubleshooting guidance.
| Characteristic | Image retention | Burn-in |
|---|---|---|
| What you see | A ghost or afterimage from earlier content | A persistent brightness or color pattern from uneven wear |
| Typical behavior | May fade when the picture changes or after compensation | Remains visible over many types of content |
| Underlying issue | Often a temporary panel state | Cumulative, uneven pixel aging |
| Can ordinary viewing reverse it? | Often, but not guaranteed | Usually requires service or panel replacement once permanent |
The terms describe a continuum rather than two completely separate defects. A faint mark that disappears is consistent with retention; a pattern that survives extended, varied viewing is more consistent with burn-in.

Why OLED panels can develop uneven wear
Each OLED pixel emits its own light instead of relying on a separate backlight. The panel controls millions of individually emitting pixels to create the image. When the same pixels repeatedly produce a bright, fixed element, those pixels accumulate more operating stress than neighboring pixels showing changing content.
Over time, that difference in aging can make one region permanently dimmer or change its color balance. The result is not a logo physically stamped into the screen; it is a difference in how the affected pixels emit light compared with the rest of the panel.
Static elements that create the most exposure
- Fixed television-channel, sports, weather and news logos
- News or stock tickers that stay in one location
- Game HUDs, health bars, maps and scoreboards
- Menus, desktop taskbars, clocks and other software interfaces
- Bright still photographs or paused video
- Black letterbox or pillarbox bars when the same borders remain for long periods
One short session is not normally the issue. The practical risk comes from bright, unchanging regions being displayed repeatedly or for long periods, especially at high panel brightness.

What long-duration testing shows—and what it cannot predict
Controlled tests demonstrate that cumulative exposure can produce permanent retention, but their schedules are far heavier and more uniform than ordinary mixed viewing.
| Test evidence | Conditions | How to interpret it |
|---|---|---|
| RTINGS 20/7 OLED-versus-LCD test | Televisions ran 20 hours per day, seven days per week, from August 31, 2017, to November 15, 2019 | An unusually severe, controlled schedule; it shows susceptibility under sustained stress, not a household life expectancy |
| RTINGS 10,500-hour comparison | At the 10,500-hour CNN checkpoint, tested 2020–2023 OLEDs and a 2017 LG C7 were run with CNN exclusively at each television’s maximum brightness in recommended SDR mode | The newer test televisions did not consistently show less permanent retention than the 2017 set under those exact conditions |
| Subpixel observation in the earlier test | The tested LG B6 showed the red subpixel degrading fastest, followed by green and blue | A result for that panel and pattern, not a universal order for every OLED generation |
These tests do not establish a universal burn-in threshold, a population-wide failure rate or the number of years every OLED television will last. They also do not show that every current model is equally susceptible. A home television usually displays varied programs, changes brightness and spends time turned off, so its exposure is different from an always-on laboratory loop.
Risk factors you can control
Reduce uninterrupted static display
Change channels or content periodically when a logo, ticker or interface occupies the same area. If a game has a static HUD, use an in-game option to hide or reposition it when available. Do not leave a paused frame or console menu on screen while away.

Use sensible brightness
Higher luminance makes a static region work harder. Using the television’s recommended picture mode for normal viewing, rather than running maximum brightness continuously, reduces unnecessary stress. This does not make burn-in impossible; it changes the cumulative exposure.
Allow automatic maintenance to run
Keep the set connected to power after switching it off. Compensation routines generally run while the television is in standby, and interrupting power at the wall can prevent them from completing.
Do not treat black bars as harmless in every situation
Occasional movies with changing content are different from a fixed format displayed for long periods every day. LG’s B3-series documentation specifically lists persistent letterbox and pillarbox bars among patterns to avoid when they remain on screen for extended periods.

Built-in protection differs by model
Manufacturers use different names and schedules for similar protections. The exact menu labels, timing and availability depend on the model and region, so the owner’s manual takes precedence.
| Manufacturer guidance | Protection or instruction | Important qualification |
|---|---|---|
| Samsung OLED support guidance | Screen Optimization runs automatically after at least four hours of accumulated use when the television is turned off; the process takes approximately 10–15 minutes | The set must remain connected to power. Samsung identifies repeated sports, news and weather logos, banners, icons and game interfaces as retention risks. |
| LG B3-series documentation | Automatic pixel cleaning runs while the television is off and connected to power; settings include lower OLED Pixel Brightness and a Logo Brightness Adjustment option | Names and controls can vary by model. The manual also warns about fixed images and persistent letterbox or pillarbox bars. |
| Sony A8F-series manual | Use normal power-off and the built-in panel protection; avoid bright static logos and clocks | Manual Panel Refresh may affect panel life. Sony’s A8F guidance says to use it only when retention is very noticeable, with once per year given as a reference. |
Automatic compensation is not the same as erasing permanent wear. It measures or balances pixel output to reduce differences; it cannot restore material that has already aged unevenly.
Recommended Free Tools
A practical prevention routine
- Leave standby power available. Turn the television off with its remote and keep it connected so scheduled compensation can operate.
- Enable the supplied protections. In the picture or panel-care menus, leave pixel shift, logo or static-image dimming, screen savers and automatic brightness controls enabled unless a specific use requires otherwise.
- Vary high-contrast content. Rotate channels, games and applications instead of displaying one fixed interface for an entire day.
- Use a screen saver or sleep timer. Configure the connected device as well as the television; a console or computer can keep sending a static frame even when the TV has its own idle setting.
- Read the exact manual before a manual refresh. A long compensation cycle is maintenance, not a routine cleaning step, and manufacturers attach model-specific warnings to it.
How to tell whether a mark is temporary
- Note when it appeared. A mark seen immediately after a bright static scene may be temporary retention; a pattern that has developed gradually after repeated use raises more concern about wear.
- Display varied full-screen content. Use ordinary programs with different colors and brightness rather than a single test image. Observe whether the outline weakens.
- Power the set down normally. Keep it connected to power and allow its automatic compensation cycle to finish. Do not repeatedly unplug it.
- Check multiple inputs and picture modes. If the same shape appears over broadcasts, streaming video and the television’s own menus, it is more likely panel-related than an HDMI source problem.
- Compare over time. A fading mark points toward retention. A stable pattern that remains after varied content and completed maintenance is more consistent with permanent burn-in.
Photographing the screen with the same content and camera settings on different days can help document whether the pattern is changing. Avoid judging from a single paused frame, because camera exposure and the source image can exaggerate faint differences.

Should you run a manual panel refresh?
Only follow the procedure specified for your exact model. Sony’s A8F manual warns that Panel Refresh may affect panel life and recommends it only when retention is very noticeable, using once a year as a reference. That instruction is model-era guidance, not a universal rule for every Sony television or every OLED brand.
Automatic maintenance and a user-launched, long refresh are not interchangeable. Starting a manual cycle repeatedly, or as a preventive ritual, can add wear without reversing established pixel aging. If the manual does not clearly authorize the operation for your symptom, contact the manufacturer or an authorized service provider instead.
What to do when burn-in appears permanent
Cleaning the glass, changing HDMI cables or installing a different streaming app cannot repair uneven pixel wear. If the mark remains visible across varied content after the model’s normal compensation process, record the model number, purchase date and photographs, then contact the manufacturer or a qualified display technician.
Whether a panel can be economically repaired depends on the model and the diagnosis. Panel replacement is usually a model-specific service decision; do not buy generic “burn-in repair” parts or run undocumented service-menu procedures.
What this means for choosing and using an OLED
OLED burn-in is a real consequence of cumulative, uneven pixel use, not an inevitable result of owning the technology. Buyers who routinely display a fixed computer desktop, a single news channel, or one game with a permanent HUD for many hours should weigh that pattern carefully and compare the exact model’s compensation features and manual instructions.
For mixed viewing, the most useful safeguards are simple: vary content, avoid leaving bright static images unattended, use moderate brightness, keep standby power connected and let the television perform its automatic care cycles. No cited test provides a guaranteed number of safe hours, so claims that a particular OLED will always last a specified time before burn-in go beyond the available evidence.
