Screen Burn-In Test
Full-screen solid colour cycles that reveal image retention and burn-in on OLED panels.
Burn-in is the classic fear of anyone buying an OLED panel, and also one of the worst explained concepts around displays. This test runs a sequence of solid colours across the full screen, with no borders and no interface elements, so that any ghost mark left on the panel becomes visible against a uniform field. Mid grey usually reveals the traces of taskbars and game HUDs, while the primaries show uneven wear between subpixels more clearly.
Before you panic, it helps to understand what you are looking for. Most of the marks people find in this test are temporary image retention, a reversible phenomenon that fades on its own after a while of varied content. Real burn-in is something else entirely: physical, permanent wear of the emissive material. Telling the two apart is the first decision to make, and that means running the test again after a few hours of normal use.
How to Use the Burn-In Test
Run the test full screen and let the sequence move through the solid colours calmly, pausing a few seconds on each one. Pay particular attention to mid grey and the lighter tones, since that is where ghost marks stand out most. Look for recognisable outlines: the silhouette of a taskbar, a rectangle where a game scoreboard usually sits, or a logo in one corner. If you find something, do not jump to conclusions. Leave the display showing varied moving content for a few hours and repeat the test: if the mark has gone or faded, it was temporary retention. If it looks identical after several days, you are dealing with permanent burn-in. The test has clear limits. It does not measure panel wear or predict remaining lifespan, and the result depends heavily on brightness, viewing angle and room lighting. On LCD panels you may also see passing retention that has nothing to do with OLED burn-in.
Retention States and What to Do
This scale helps you classify what you saw during the test and decide the next step. The key distinction lies between what corrects itself and what has no way back.
| State | How it looks | What to do |
|---|---|---|
| No retention | Solid colours look completely uniform from corner to corner | Nothing to do; repeat the test every few months as a routine check. |
| Mild retention | A very faint shadow visible only on mid grey and from certain angles | Show varied content for a few hours and check again afterwards. |
| Visible retention | Recognisable interface outlines showing up across several colours | Run the panel refresh cycle and lower brightness for everyday use. |
| Permanent burn-in | The mark stays identical after days of normal use and refresh cycles | This is real wear; check your warranty and avoid static elements from now on. |
| Severe burn-in | Clear marks even over moving content and in ordinary scenes | The panel is degraded; consider repair or replacing the display. |
Temporary Retention Versus Permanent Burn-In
Temporary image retention is a reversible effect. When the same pattern stays fixed on screen for a long stretch, the pixels involved sit momentarily in a different state from their neighbours and take a while to settle. The result is a faint shadow visible on uniform backgrounds that disappears by itself after a period of varied content. It implies no damage and does not shorten panel life: you simply need to stop showing the image that caused it.
Permanent burn-in is physical wear. In an OLED panel each pixel emits its own light through an organic material that degrades with use, and it does so unevenly: regions that have shown the same element for years lose brightness before the rest. That accumulated difference never comes back, because it is worn material rather than an electrical state. The usual culprits are static elements that stay fixed for thousands of hours: game HUDs, taskbars, television channel logos and scoreboards.
Manufacturers apply several mitigation measures. Pixel shifting moves the image a few imperceptible points so the edges of a static element never land on the same pixels forever. Compensation refresh cycles even out wear by running a routine once the set has been off for a while, with short periodic versions and longer ones that trigger every few hundred hours. None of these reverses wear that has already set in, but they do push its appearance a long way back. It is worth adding that LCD panels do not suffer burn-in in the strict sense, because their light comes from a shared backlight rather than per-pixel organic material. They can still show passing image retention caused by liquid crystal behaviour, a mark that clears by itself within minutes or hours. If you have an LCD and see a shadow, it is almost certainly temporary.
Tips for Preventing Burn-In
- Auto-hide the taskbar and cut down on fixed desktop elements when running an OLED.
- Lower overall brightness, since emissive wear grows quickly with sustained luminance.
- Enable pixel shifting and the automatic refresh cycles your manufacturer provides.
- Let the display finish its maintenance routine after shutdown instead of cutting power immediately.
- Avoid leaving a game paused with the HUD on screen for hours, and use a real screen saver.
- Rotate your content: hours on end with the same static interface is the scenario that wears panels fastest.
Frequently Asked Questions
What is the difference between image retention and burn-in?
Image retention is a temporary, reversible effect: a shadow that appears after a fixed pattern has been displayed for a long time and fades on its own with varied content. Burn-in is permanent physical wear of the emissive material in an OLED panel, caused by thousands of hours of the same static element. The way to tell them apart is repeating the test after several hours of normal use.
Can an LCD monitor suffer burn-in?
Not in the strict sense. An LCD lights the image with a shared backlight and has no organic material degrading pixel by pixel, so it cannot wear out in a localised way like an OLED. It can show passing retention caused by liquid crystal behaviour, but that mark clears by itself within minutes or hours and leaves nothing behind.
What causes burn-in on an OLED panel?
Static elements that stay in the same position for thousands of hours: a game HUD, the desktop taskbar, a channel logo in a corner or a permanent scoreboard. High brightness accelerates the process considerably, and the most demanding colours wear their subpixels sooner than the rest, which also leaves a colour cast in the affected area.
Can burn-in be repaired?
Permanent burn-in cannot be reversed because it is worn material, not an electrical state. Compensation refresh cycles can partly even out the wear and make the mark less noticeable, but they do not restore lost brightness. If the defect is severe and the display is still under warranty, check the manufacturer coverage before trying home remedies.
Is it safe to game for long hours on an OLED?
Yes, with sensible precautions. The risk does not come from playing a lot, but from holding the same static HUD at high brightness for thousands of hours. Lowering brightness, enabling the manufacturer mitigation features, alternating between different games and not leaving a session paused overnight bring the risk down to a perfectly acceptable level.
