To check an OLED TV for burn-in, first switch away from the content where you noticed the mark, then inspect the screen with varied content and uniform full-screen colors or gray. If your TV has a built-in Picture Test, use it: a mark visible in the TV’s own test is more likely to involve the display than an HDMI device or cable. A temporary ghost may fade; a persistent outline that remains across content and in the built-in test deserves manufacturer or qualified-service advice. No single visual check can prove the physical cause.
What to check—and what the result can tell you
OLED image retention is a visible trace left after an image has been displayed. A faint trace that fades after the content changes is generally temporary. Burn-in is a form of image retention that lasts much longer and is usually visible over other content. LG describes that distinction in its support guidance, but the available guidance does not establish a universal number of minutes or hours that proves a mark is permanent.
The aim of a home check is to gather clues, not to certify panel damage. Look at whether the mark fades, whether it appears with different content, whether it is present in the TV’s own diagnostic image, and whether it resembles a fixed logo or interface element. A signal problem or a screen-uniformity artifact can look similar, so do not diagnose the panel from one HDMI source or one test image alone.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Think of the checks as comparisons rather than a pass/fail test. Persistence over time and varied content, visibility in the TV’s built-in test, the shape and location of the mark, and whether it changes after the TV’s normal model-specific care cycle all add context. None of those observations, alone or together, identifies the physical cause with certainty. A service provider or manufacturer can advise on diagnosis for the exact model.

Check the screen safely, step by step
-
Change the content and observe the mark
Switch away from the program, game, or app where you first noticed the trace. Play varied ordinary content rather than leaving another still image on screen. Note whether the mark becomes fainter or disappears. LG says ordinary image retention commonly fades after a moment or two; persistent burn-in lasts longer and usually remains visible during other content. Treat that as a useful distinction, not a timed pass/fail test.
Pay attention to whether the trace matches something that was fixed in place, such as a channel logo, news ticker, or game interface. A recognizable outline can be a useful clue about what was displayed, but it does not prove burn-in. If the mark is only visible in one scene or app, check it against other content before drawing a conclusion.
-
Show uniform full-screen colors and gray
Display full-screen solid colors and shades of gray. Uniform fields make outlines easier to notice than detailed scenes, which can conceal subtle marks. You can use a built-in test-pattern video or a TV-provided diagnostic pattern; the cited guidance does not establish that you need a physical test device. Avoid judging the screen from a single shade: check several fields, and note the color and location where the artifact is easiest to see.

Make a note of which fields reveal the symptom most clearly and whether its shape remains consistent. If the TV has a built-in diagnostic pattern, prefer that as an additional comparison because it avoids relying only on one connected source. These checks help describe what you see; they cannot certify that a mark is permanent.
-
Run the TV’s built-in Picture Test, if available
Open the manufacturer’s Picture Test or equivalent display diagnostic. Samsung’s support instructions say a defect that appears in the test can warrant support, while a normal test image may point toward an external device or cable when the problem occurs only from a connected source. The exact menu path varies by TV year and software version, so use the instructions for your model rather than assuming a universal sequence.

Follow the on-screen instructions for the test and note its result. If you cannot find the option, check the TV’s model-specific manual or support page; a missing or differently named test is not itself evidence of a fault. A normal result is informative when the symptom is limited to one external source, but it does not rule out every possible panel issue.
-
Compare inputs and connected equipment
If the mark appears only while using one set-top box, console, streaming device, or HDMI input, change the input and, where practical, try another cable or device. Do not conclude that the OLED panel is damaged from one source alone. If the built-in test is clean and the defect does not appear through other sources, investigate the source device, connection, and cable before escalating a panel concern.

See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.Keep the comparison simple: change one part of the signal path at a time when practical, and note whether the symptom follows the source or remains on other inputs. If it appears in the TV’s own Picture Test as well as through multiple sources, that is a stronger reason to contact support than a symptom confined to one device. It still is not a definitive diagnosis.
-
Record a persistent result
If the same mark remains in the TV’s own test and across varied content, photograph it and write down the TV model, software version, input, and conditions in which it appears. Contact the manufacturer or a qualified service provider for model-specific diagnosis. A photo and visual inspection can help explain the symptom, but neither identifies the physical cause with certainty.
Include when you first noticed the mark, the kind of content that was on screen, whether it faded after changing content, which uniform fields made it visible, and whether it appeared in the Picture Test. If the symptom changes, worsens, or is visible only from one source, include that too. These observations give support a clearer description without presuming that the screen has burn-in.

How to distinguish retention from similar-looking problems
| What you observe | What it may indicate | What to do next |
|---|---|---|
| A faint ghost after changing content that fades | Temporary image retention is a possibility. LG describes ordinary retention as commonly fading after a moment or two. | Continue with varied content and observe whether it clears; there is no universal wait time that proves permanence. |
| A logo, ticker, or game-interface outline that remains over other content | Persistent image retention or burn-in is possible, especially if the shape corresponds to static material. | Check uniform fields and the TV’s built-in Picture Test, then seek model-specific service advice if it remains. |
| A defect appears from one connected source but not in the TV’s own test | An external device, cable, or signal path may be involved rather than the panel. | Compare another input, cable, or device before treating it as a panel defect. |
| Straight vertical or horizontal bands, rather than a recognizable fixed-image outline | A screen-uniformity artifact or banding can resemble retention. Tom’s Guide notes that some uniformity artifacts are distinct from burn-in. | Do not assume a pixel-refresh routine will remove it. Escalate an unresolved or worsening issue instead of repeatedly running refresh routines. |
These patterns are clues, not mutually exclusive diagnoses. A single visual test cannot establish whether an artifact is permanent, identify every cause, or replace service inspection.
Shape helps frame the next check, but it is not conclusive. A logo-shaped trace that persists over other content deserves closer attention to retention; broad or straight bands may instead be a uniformity issue. If a mark is visible only through a connected source, compare it with the TV’s built-in test and other inputs. If the appearance is unclear, worsening, or present in the TV’s test, describe it to support rather than repeatedly running maintenance routines in an attempt to identify it.
Pixel Shift, Pixel Cleaning, and panel refresh are not the same on every TV
Manufacturers use different names and schedules for screen-care features. Depending on the model, a feature may shift the displayed image slightly, run an automatic maintenance cycle in standby, or offer a manually started panel refresh. Read the exact TV’s manual before starting a manual cycle: menu labels, availability, duration, and recommended frequency vary. Do not repeatedly trigger a manual refresh because a mark remains; the cited guidance does not support promising that these routines reverse established permanent burn-in.
Pixel Shift is a preventive feature that periodically moves the image slightly, rather than a user-run diagnostic. Sony’s help guide says to leave Pixel Shift enabled under normal circumstances. Pixel Cleaning, Screen Optimization, and Panel Refresh are names used for maintenance functions on particular products; the names do not mean that every model runs the same process or offers the same controls. Check whether a routine is automatic or manual, what the manufacturer recommends, and whether the TV needs to remain in standby or connected to power.
Do not use the duration or interval listed for one brand, model, or product type as a rule for another. In particular, the Philips example below is for one named QD-OLED monitor, not a Philips television. A mark that remains should lead to support advice, not repeated manual cycles or an assumption that the routine is a guaranteed fix.

| Manufacturer guidance in the cited material | What it says | Scope and caution |
|---|---|---|
| LG | The support page describes a screen saver that activates after about two minutes of inactivity on a No Signal screen or paused video. It describes automatic Pixel Cleaning after four cumulative hours and a longer calibration after 2,000 cumulative hours. It also discusses a logo-brightness setting. | These are LG-specific descriptions; manual options and run times depend on model. Confirm the behavior for your TV. |
| Samsung | Regional support guidance describes Screen Optimization running automatically when the TV is turned off after at least four hours of use. It also provides a Picture Test. | Menu paths vary by model year and software, and Samsung warns that menus can differ. Follow your model’s instructions. |
| Sony | The cited OLED help guide says Pixel Shift periodically moves the image and should ordinarily remain enabled. It describes manual Panel Refresh for particularly noticeable retention, with a once-a-year reference limit and a run time of about an hour. | This is model-specific guidance, not a general schedule for all OLED TVs. Check the manual before using manual Panel Refresh. |
| Philips 34M2C8600 QD-OLED monitor | Philips’ 2025 care guide for this monitor describes automatic refresh after 16 cumulative hours, around 15 minutes per run, and a menu counter. | This example applies to the named monitor, not Philips TVs generally or other monitors. |
Automatic care can depend on how the device is used and whether it can enter standby. Keep the TV connected to power when its manual says that automatic care needs standby power. Do not disable a protection feature or apply another model’s schedule based on advice written for a different TV.
Reduce the chance of future image retention
- Vary what is displayed rather than leaving the same bright, fixed graphics in place for long periods. Static channel logos, news tickers, and paused game interfaces are cited risk factors.
- Use the TV maker’s screen saver, logo-dimming, or other protective features where recommended. LG identifies vivid mode and prolonged high brightness as additional risk factors.
- During a long pause, turn the TV off or let its screen saver operate instead of leaving a static picture displayed.
- Choose comfortable brightness and contrast settings for your room and viewing habits. RTINGS discusses varied content, comfortable settings, built-in OLED care features, and turning a TV off during long pauses as practical precautions.
- Follow the manual’s instructions for standby and automatic maintenance. The exact behavior is model-dependent; do not assume a care cycle runs on the same schedule across brands or models.
These precautions are about reducing avoidable exposure to static, bright graphics and following the protection features designed for your set. They are not a guarantee against every display issue. If a screen saver, logo-dimming control, or maintenance option is available, use the model’s own instructions rather than disabling it because a different TV handles care differently.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.When to contact support
Contact the manufacturer or a qualified repair provider when a mark remains visible across varied content and in the TV’s own diagnostic test, or when an artifact is worsening or unexplained. Share the photo and the model, software version, input, and test conditions you recorded. Ask for diagnosis specific to the model and region, and check the warranty terms that apply to that exact TV. A test pattern is a way to observe the symptom, not a repair, and the maintenance guidance above does not establish that a refresh routine will cure permanent burn-in.
Before arranging service, gather the model number and the details of the symptom, then consult the manufacturer’s support channel or a qualified provider. Warranty terms vary by model and region, so do not assume that a particular mark is covered or excluded without checking the terms for your TV. No universal repair price or paid program applies from the information here; ask the manufacturer or provider about diagnosis, coverage, and any costs before authorizing work.
Recommended Free Tools
You do not need to buy a special physical tester to perform the checks described here. A built-in Picture Test or a free test-pattern image can help reveal a symptom, while a replacement TV is not a diagnostic tool. A generic HDMI cable is relevant only when you are checking whether a signal-path issue is limited to one source; cleaning products do not address pixel wear. None of these purchases should be treated as a way to diagnose burn-in.

Frequently Asked Questions
How can I check an OLED TV for burn-in?
Change to varied content, inspect uniform full-screen colors and gray, and run the TV’s built-in Picture Test if available. Note whether the mark fades, appears across content, and is visible in the TV’s own test. These are clues, not a definitive diagnosis.
How can I tell temporary image retention from burn-in?
A temporary ghost may fade after the content changes. LG says ordinary retention commonly fades after a moment or two, while burn-in lasts longer and is usually visible over other content. There is no universal wait time that proves a mark is permanent.
Can I run Pixel Cleaning or Panel Refresh to fix burn-in?
Features and recommendations vary by model, and the guidance does not establish that a maintenance routine reverses established permanent burn-in. Check your exact model’s manual before starting a manual refresh, and do not repeatedly run one without model-specific guidance.
What if the mark appears only on one HDMI input?
Compare another input, cable, or connected device and run the TV’s built-in Picture Test if it has one. A defect limited to one source may involve the external device, cable, or signal path rather than the panel.
Should Pixel Shift be enabled?
Sony’s cited OLED help guide says Pixel Shift should ordinarily remain enabled under normal circumstances. Follow the instructions for your own TV, since settings and recommendations are model-specific.
Do I need to buy a burn-in tester or special cable?
No dedicated physical tester is established as necessary. A TV’s built-in diagnostic or a free test pattern can help with a visual check. A different cable is relevant only when comparing a suspected source or signal issue.
When should I contact the manufacturer or a repair provider?
Seek model-specific advice if a mark remains across varied content and in the TV’s own test, or if it is worsening or unexplained. Provide a photo, model and software details, input, and the conditions in which it appears; check warranty terms for your model and region.

Use varied content, uniform color and gray fields, and the TV’s own Picture Test to gather clues. A fading ghost may be temporary; a mark that persists across content and in the built-in test merits support advice, not repeated manual refresh cycles. Follow care instructions for the exact model, since neither a visual check nor a maintenance routine can guarantee a diagnosis or cure.
