OLED screens deliver the deepest blacks and most vibrant colours of any display technology — but they come with a known weakness: burn-in and image retention. If you own an OLED TV, monitor, or smartphone, knowing how to test for burn-in and how to prevent it could save you from an expensive replacement. This guide covers everything you need to know.

What Is OLED Burn-in?

OLED stands for Organic Light-Emitting Diode. Each pixel in an OLED display generates its own light, using organic compounds that degrade over time. When certain pixels are pushed harder than others — by displaying a static, bright image for long periods — those pixels age faster. The result is a permanent ghost image of the static content that remains visible even when the screen shows different content.

Burn-in is permanent and irreversible. Image retention, by contrast, is a temporary version of the same phenomenon — a ghost image that fades after the screen has cycled through different content for a while. The two are often confused, but image retention does not cause lasting damage.

How to Test for OLED Burn-in

1. Display a solid grey screen – A mid-grey (50% brightness) image makes retained ghosts most visible. Open our grey screen tool and go full screen.
2. Look for ghost outlines – Common burn-in patterns include TV channel logos, news tickers, video game HUD elements (health bars, minimaps), and navigation bars on smartphones.
3. Test with solid red, green, and blue – Use our colour test tool to cycle through primary colours. Burn-in often shows unevenly across different colour channels.
4. View at different angles – Some burn-in is more visible from an angle than straight-on.
5. Compare brightness uniformity – Burned areas may appear slightly dimmer or slightly warmer in colour than surrounding areas.

Common Sources of OLED Burn-in

• Static TV channel logos – News channels and sports networks keep bright logos in fixed positions for hours at a time.
• Game HUD elements – Fixed health bars, ammo counts, and minimaps are the most common cause of gaming OLED burn-in.
• Taskbars and dock bars – On OLED monitors used for computing, the Windows taskbar or macOS dock can cause horizontal burn-in bands.
• Smartphone status bars – The battery icon, signal bars, and time display are always visible on phones and are a top cause of OLED smartphone burn-in.
• Subtitles and news tickers – Fixed-position text areas that run for long sessions.

How to Prevent OLED Burn-in

• Enable pixel shifting – Most OLED TVs and monitors include a pixel shifting or screen move feature that imperceptibly moves the image by a few pixels to distribute wear more evenly.
• Use auto-brightness limiting – OLED brightness should be kept below 200 nits for everyday use. High peak brightness over static content accelerates degradation.
• Enable screen savers and sleep timers – Set your display to turn off or show a screensaver after 5–10 minutes of inactivity.
• Rotate your wallpaper – Dynamic wallpapers change regularly, preventing any single image from dominating pixel usage.
• Use dark themes – On OLED, dark mode reduces the light output of many pixels, slowing overall degradation.
• Run the built-in pixel refresher – LG, Samsung, and Sony OLED TVs include a pixel refresh cycle. Run it periodically (every few months) to recalibrate organic compounds.

Which OLED Devices Are Most at Risk?

Devices with static interface elements used for long daily sessions carry the highest risk: OLED gaming monitors, OLED TVs used as PC monitors, and flagship OLED smartphones. OLED TVs used solely for watching varied content (films and streaming) at moderate brightness carry a low risk and generally last over 10,000 hours without visible burn-in.

Frequently Asked Questions

Can you fix OLED burn-in?

True burn-in — permanent pixel degradation — cannot be reversed. However, image retention (temporary ghosting) can often be cleared by running the manufacturer's pixel refresher cycle or by displaying a bright white screen for 30–60 minutes to even out pixel aging.

How long does it take for OLED burn-in to occur?

Under typical mixed-content viewing conditions, modern OLED panels are highly resistant and can last 5–10 years without burn-in. The risk increases dramatically if a static, high-brightness image is displayed for more than 4–6 hours per day continuously.

Does the OLED burn-in test work on QD-OLED panels?

Yes. QD-OLED (Quantum Dot OLED) uses the same organic emitter technology and is susceptible to the same burn-in mechanism. The test procedure is identical. QD-OLED panels are generally considered slightly more resistant to burn-in than traditional WOLED designs due to their different sub-pixel structure.
