OLED Burn-In Test - How to Check Your OLED Monitor

The OLED burn-in test is a retention check, so it should be run after the panel has seen normal use. OLED burn-in occurs when static elements displayed for extended periods cause uneven degradation of the organic emitter material in individual pixels, leaving a ghost image visible on other content. RTINGS found that long periods of static content cause OLED burn-in through cumulative subpixel degradation, while LG says extreme usage can create retention that mitigation features may reduce but not make impossible.¹ Modern OLED displays often include retention-prevention features, but they reduce risk rather than eliminate it; short-term retention can sometimes improve after a panel cleaning cycle.²

What the grey test reveals and why

Solid grey is a useful background for detecting image retention and early burn-in on an OLED panel because RTINGS records 50% grey, red, green, blue, cyan, magenta, and yellow photos during its burn-in test, and grey fields make luminance differences easier to compare across the screen.¹ On a mid-grey pattern, a retained ghost appears as a slightly lighter or darker region shaped like the static element that caused it, typically a taskbar, game HUD, or browser bar.

Why grey exposes retention first

The test works because retained emitter degradation produces slightly different brightness output from affected pixels compared to unaffected ones. On dynamic content, this difference blends into normal image variation and goes unnoticed. On a uniform grey field, the luminance difference stands out as a visible region. Run the grey pattern long enough to notice faint regions; if you suspect retention, compare the result before and after a cleaning cycle rather than judging from one quick glance.

If a faint region appears on the grey test but disappears when you switch to a dynamic content window, the retention is still mild and likely reversible with a panel cleaning cycle. A ghost that persists across multiple content types and remains visible on the grey pattern after extended use is the finding that warrants systematic documentation and potentially a warranty discussion.

How to interpret a faint ghost image

Before diving into the specific details of this section, it is worth establishing the broader context that frames what you are testing and why these particular characteristics matter for your daily experience, because understanding the underlying principles behind each test helps you make more informed decisions about panel quality and return thresholds. ### How to interpret a faint ghost image

A faint ghost visible on the grey test pattern does not automatically mean permanent burn-in, and proper diagnosis requires a systematic approach rather than a single alarming observation. First document exactly what static content was displayed on screen before the test and how long it remained visible without changing, then run the monitor's recommended pixel refresh cycle or allow an extended rest period before retesting under identical conditions. If the ghost visibly weakens or disappears after the refresh cycle or rest period, you were observing temporary image retention rather than permanent organic material degradation. If the ghost remains clearly visible in the exact same screen location after multiple checks separated by adequate rest periods, document it thoroughly as a persistent retention image that may warrant a warranty claim.

Always use the identical brightness setting and room lighting conditions for each retest, because changing the brightness can make a faint ghost appear to improve or worsen without any actual change in the panel's physical condition. A reproducible result documented under consistent, recorded conditions is significantly more useful for warranty discussions than a single alarming photo taken immediately after a long static-content session when retention is expected to be at its most visible.

Running the panel self-cleaning cycle after testing

If you detect early retention, run the panel's built-in pixel refresh or self-cleaning cycle before pursuing any return or warranty claim. Many OLED gaming monitors include this feature in the OSD menu under names such as Pixel Cleaning, Pixel Refresh, Panel Care, or Self-Clean. ASUS says Pixel Cleaning calibrates issues that may arise after long use, takes about six minutes, and is recommended every four hours.³ Corsair describes five-minute pixel refresh cycles after shutdown.⁴

What pixel refresh can and cannot fix

Retention that developed recently, particularly from short sessions with static content, is the most likely to respond to a cleaning cycle. ASUS says residual image or burn-in conditions may return to normal after the screen is off for at least one hour, or after repeated pixel cleaning if the issue remains.³ Retention that developed over months of heavy static use is harder to reduce and may not respond significantly to a single cycle.

OLED care settings to configure after testing

After establishing a retention baseline, configure the monitor's OLED protection features to slow future degradation. Corsair describes OLED burn-in prevention technologies, including pixel refresh, on its Xeneon Flex monitor, so use your model's equivalent pixel-refresh or pixel-shift setting when available.⁴ Set a screen timeout so the panel dims or sleeps instead of leaving a static image on screen indefinitely.

Configuring brightness and gaming-use protection

For gaming use, lower peak brightness to the minimum comfortable level for your room. LG says most burn-in cases come from static on-screen elements displayed uninterrupted for many hours or days at peak brightness, so reducing brightness lowers one of the main risk factors.² Use the grey test pattern in this tool as a periodic benchmark: run it every few months to track whether retention is developing in specific regions before it becomes visible on normal content.

When to use this

Run this test periodically after months of regular use, using the same grey field pattern from this periodic OLED retention benchmark that covers every OLED display you own, particularly if you display static content like a taskbar, game HUD, or browser chrome for long sessions. Also run it when buying a used OLED monitor to assess how much retention has already developed before purchase.
