Short answer: Neither LG nor Samsung has a proven, brand-wide reliability advantage in the available evidence. OLED burn-in remains possible when the same static elements accumulate on the screen, while varied viewing is not expected to create a burn-in problem for most viewers, according to RTINGS’ October 2, 2026 update. The clearest warranty difference documented here is for US 2025 LG models: G, Z, and M televisions have five-year panel coverage, but only the first year includes parts and labor. Samsung’s current US OLED warranty terms were not established in the material available for this comparison, so a warranty winner cannot be declared.
What the evidence actually supports
Reliability, burn-in risk, and warranty protection are related but different questions. A television can show no visible degradation in an accelerated test yet have a shorter written warranty, or carry longer panel coverage while still charging labor after the first year. Comparing LG OLED and Samsung OLED fairly therefore requires the exact model, model year, country, viewing pattern, test checkpoint, and warranty document.
| Question | Evidence-based answer | What it means for a buyer |
|---|---|---|
| Is OLED burn-in still possible? | Yes. RTINGS says cumulative display of the same static elements can produce burn-in, including on modern OLED televisions. | Static-heavy use carries more risk than varied viewing; no OLED should be described as burn-in-proof. |
| Does varied viewing usually cause a problem? | RTINGS’ October 2, 2026 Longevity 3.0 update says varied content is not expected to create a burn-in problem for most viewers. | Movies, changing programs, and mixed everyday use are less concerning than a fixed logo, ticker, or game interface shown repeatedly. |
| Is LG more reliable than Samsung? | The available observations involve individual models, samples, conditions, and checkpoints. They do not establish a current brand-wide winner. | Choose by exact model and use case rather than assuming one logo guarantees longer life. |
| Does LG have a longer warranty? | For US 2025 G, Z, and M series, LG documents five years of panel coverage; years two through five are panel-only and labor is charged. | “Five-year panel warranty” is not the same as five years of full repair coverage. |
| Can Samsung’s current US warranty be ranked against it? | Authoritative US terms for the current S95F and S90F models were not established in the captured material. | Read the exact Samsung limited-warranty document for your country and SKU before relying on a comparison. |
How OLED burn-in happens and why usage matters
OLED pixels emit their own light. When the same bright shapes remain in the same locations over a long cumulative period, those areas can age differently from the rest of the panel. The resulting unevenness is commonly called burn-in or permanent image retention. RTINGS’ October 2026 update describes this as a real possibility even for modern displays, but also says that varied content is not expected to create a burn-in problem for most viewers.

A single evening with a static menu is not equivalent to repeatedly displaying the same fixed elements for many hours over a long period. Risk rises with the amount of time, brightness, and repetition involved, but the available evidence does not provide a universal hour threshold that applies to every model or household.

| Viewing pattern | Relative concern | Reasoning |
|---|---|---|
| Mostly varied films, series, sports, and changing broadcast content | Lower concern according to RTINGS’ practical guidance | Picture content changes across the panel instead of repeatedly stressing one fixed pattern. |
| Mixed use with occasional static menus, scoreboards, or game interfaces | Intermediate | Short, infrequent static sessions are different from continuous exposure, but cumulative repetition still matters. |
| Daily use of fixed news tickers, channel logos, desktop taskbars, or a game HUD in the same place | Higher concern | The same elements are displayed repeatedly, which is the condition associated with cumulative uneven aging. |
These categories are decision aids, not a guarantee for a particular panel. Two televisions of the same model can age differently, and a laboratory stress test intentionally creates harsher conditions than many homes.
What RTINGS’ longevity tests show—and what they cannot prove
RTINGS describes its longevity project as a 100-TV accelerated test designed to examine degradation and failures, including component-level causes. Sets remain under test and updates are published as observations develop. That makes the project useful for finding failure modes over time, but it is not a population survey of every owner or every current LG and Samsung television.
Early two-month observations
In an earlier investigation, RTINGS reported possible permanent image retention on two QD-OLED samples—Samsung S95B and Sony A95K—after two months under the study’s conditions. Its LG WOLED samples, C2 and G2, remained clean at that checkpoint. This is a comparison of named samples at one point in one test, not proof that every QD-OLED is less reliable than every WOLED.
Recommended Free Tools
The observation is still useful because it shows why panel technology and test conditions should be discussed separately from brand reputation. A result on one sample can identify a question for continued monitoring without supplying a failure rate for an entire product family.
January 21, 2026 update
RTINGS said discoloration on its Samsung S95C sample had worsened. The affected area roughly corresponded with a hot part of the television, but RTINGS could not determine whether the cause was degradation in the electroluminescent layer or in the quantum dots. That is a documented observation with an unresolved mechanism, not a confirmed diagnosis for all S95C units or Samsung OLEDs.

The same update said one LG G3 data set remained before that test’s official end. A data set still running is not a pass or fail; it simply means the final checkpoint had not yet been reached.
Longevity 3.0 update, October 2, 2026
RTINGS’ Longevity 3.0 account intentionally exposes displays to demanding patterns so degradation and failures can be detected sooner than they would be in ordinary mixed viewing. The update states that varied content is not expected to create a burn-in problem for most viewers, while retaining the warning that static elements can cause burn-in cumulatively.
Because the schedule is accelerated and the patterns are deliberately demanding, a change seen in the project should be read as evidence that a failure mode can occur under those conditions. It should not be converted into a prediction that a normal household will see the same result at the same time.
Why the test cannot produce a blanket LG-versus-Samsung ranking
RTINGS’ updates involve particular models, samples, test schedules, and checkpoints. They do not control every variable that differs between products, such as panel generation, heat management, firmware, brightness behavior, and manufacturing variation. The material therefore supports cautious model-level observations, not a statement that one manufacturer’s current OLED lineup is categorically more reliable.
RTINGS’ display-technology comparison uses Samsung S95F, LG G5, and LG C5 as current examples while discussing QD-OLED and WOLED. It also states that OLED can eventually experience burn-in. The comparison is useful for understanding the technologies, but it does not establish a reliability hierarchy between the two brands. See RTINGS’ QD-OLED versus WOLED comparison, its longevity-test methodology, the three-month investigation, the test updates, and the Longevity 3.0 update.

QD-OLED and WOLED: what you can and cannot infer
QD-OLED and WOLED are different panel approaches, and the RTINGS comparisons use examples from both. A difference in panel construction can help explain why a particular sample behaves differently in a stress test. It does not, by itself, prove that every television using one approach will outlast every television using the other.
| Example named in the current RTINGS comparison | Technology context in that comparison | Reliability conclusion supported here |
|---|---|---|
| Samsung S95F | QD-OLED example | No brand-wide or technology-wide reliability verdict follows from the example alone. |
| LG G5 | WOLED example | Its inclusion does not establish that all LG WOLED models are more durable than all Samsung QD-OLED models. |
| LG C5 | WOLED example | Panel technology should be considered alongside model design, usage, and warranty terms. |
When you compare two televisions, record the exact model number and panel description rather than assuming that a brand uses one technology in every size or series. The test evidence cited above is tied to named units; moving from one model to another changes the evidence base.
US warranty comparison: the verified LG terms
The clearest warranty distinction in the available documentation concerns LG’s 2025 US lineup. LG’s announcement says the G, Z, and M series receive a limited five-year panel warranty. The first year covers the panel, parts, and labor. Years two through five cover the panel only, with labor charged. LG’s G5 support information repeats that distinction.
| US 2025 model or series | Panel term | Parts and labor | What the wording does not establish |
|---|---|---|---|
| LG G5; G, Z, and M series eligibility as described by LG | Five years of limited panel coverage | Year 1: panel, parts, and labor. Years 2–5: panel coverage; labor charged. | It does not automatically mean five years of full service, and the cited wording does not promise coverage for every instance of burn-in. |
| LG C5 (US support listing) | One year listed for the product support warranty | One year of parts and one year of labor | The cited C5 page does not list the G/Z/M extended-panel provision. |
Sources: LG’s 2025 US OLED lineup announcement, LG G5 US support, and LG C5 US support.
Before purchase, open the warranty document supplied with the exact model. Confirm the eligible purchase date, original-purchaser requirement, exclusions, service procedure, and whether the language addresses image retention or burn-in explicitly. A panel-only term can be valuable if a covered panel defect occurs, but you may still have to pay for labor after the first year.

Samsung warranty information that remains unverified here
Authoritative Samsung US warranty terms for the current S95F and S90F OLED models were not established in the available material. That means this comparison cannot responsibly state a Samsung term, claim that burn-in is covered, or claim that it is excluded. Retailer summaries and forum comments should not substitute for the exact Samsung limited-warranty document for your country and model.
When checking a Samsung television, capture the warranty page or included document for the precise SKU. Record the panel term, parts term, labor term, exclusions, geographic limits, original-purchaser rules, and claim instructions separately. If image retention is not mentioned, ask Samsung or the seller to clarify whether it is treated as a covered defect, an exclusion, or a case-by-case determination.
What a broad reliability survey can—and cannot—tell you
LG’s US page republishes Consumer Reports survey results covering 121,881 new televisions purchased by surveyed members between 2015 and 2025. The page lists predicted brand-reliability scores of 94/100 for LG and 86/100 for Samsung. Those figures are attributed to Consumer Reports but republished by LG in 2026.
The survey is about overall television brands, not an OLED-only comparison and not necessarily the current 2025–2026 models discussed here. It can provide broad ownership context, but it cannot settle the narrower question of whether one company’s present OLED panels have lower burn-in or failure rates. See LG’s Consumer Reports summary and check the scope before applying the scores to an OLED purchase.
How to choose between an LG OLED and a Samsung OLED
1. Classify your viewing pattern
- List fixed elements. Note whether you leave a channel logo, news ticker, desktop interface, scoreboard, or game HUD in the same location for long periods.
- Estimate repetition. A static element displayed occasionally is a different exposure from one shown every day. Write down the routines that could create cumulative stress.
- Decide whether OLED’s strengths justify the trade-off. If your use is dominated by unchanging interfaces, treat burn-in risk as a primary selection criterion rather than an afterthought.
2. Compare exact models, not logos
Write down the full model number, screen size, model year, and panel approach shown in the manufacturer’s specifications. Then match that exact model to independent test observations. An observation on a Samsung S95C, for example, is not evidence about every Samsung OLED; an LG G3 data set is not a result for every LG series.

3. Separate the image-quality decision from the reliability decision
Choose the picture characteristics and room fit you want first, then examine degradation evidence and warranty protection for that model. A panel technology comparison can explain performance differences, but it cannot replace a warranty document or a usage-risk assessment.
4. Read the warranty line by line
- Is the display panel covered, and for how many years?
- Are parts and labor both covered for the entire stated period?
- Does the text mention image retention or burn-in, either as covered damage or an exclusion?
- Does it apply to your country, exact SKU, purchase channel, and original purchaser status?
- What proof of purchase and service steps are required?
5. Keep evidence from the day you buy
Save the invoice, model number, serial number, warranty card, and a copy of the online warranty terms. If a visible change appears later, photograph it with the television displaying a neutral image and record the date, content being watched, approximate hours, and whether the pattern is fixed. Those details help a service department evaluate the claim without turning a general test result into a diagnosis.
Practical ways to reduce avoidable exposure
No setting can be promised to prevent burn-in, and the available evidence does not justify calling any pixel-care feature a guarantee. The defensible approach is to reduce repeated static exposure where your routine allows it.

- Do not treat a television used as a constant desktop monitor or information panel as equivalent to mixed film and program viewing.
- Follow the operating and care instructions supplied for the exact model, because procedures and labels can differ by generation.
- Keep records of unusual discoloration or persistent retention rather than assuming it is either harmless or automatically covered.
- Contact the manufacturer or seller before attempting any repair; panel replacement is not a normal owner maintenance task.
If you notice retention or discoloration
- Stop the repeated static source. Change the content and note what had been displayed when the pattern appeared.
- Document the symptom. Record the model, purchase date, viewing routine, and photographs showing the affected area.
- Check the exact warranty. Look for panel, parts, labor, image-retention, and burn-in language rather than relying on a headline such as “five-year panel warranty.”
- Open a support case. Provide the requested proof of purchase and describe the conditions accurately. Do not claim that a laboratory checkpoint proves your individual set has the same failure.
- Ask for the remedy in writing. Confirm whether the proposed service covers the panel, labor, shipping, and any diagnostic fee under your market’s terms.
The January 2026 RTINGS observation illustrates why a visible pattern should be reported as an observation, not assigned a cause by the owner: discoloration corresponded roughly with a hot area, yet the test team could not determine whether the electroluminescent layer or quantum dots were responsible.
Bottom line for an LG-versus-Samsung purchase
For varied everyday viewing, the available evidence does not justify avoiding either brand on reliability grounds. For static-heavy use, every OLED purchase carries a meaningful cumulative burn-in consideration. RTINGS’ accelerated project is valuable for identifying model-specific behavior, but it is not a brand reliability league table.
In the United States, the documented 2025 LG G5/G/Z/M provision is materially different from the C5 listing: extended panel coverage exists for the former, while the C5 page states one year of parts and labor. Samsung’s comparable current US terms must be verified from Samsung’s own document before you assign a value to its warranty. The most defensible choice is the exact model whose usage fit, test evidence, and written coverage match your risk tolerance.
