OLED Burn-In Test

Pick a mode and press Fullscreen. Solid colors reveal retention; checkerboard exposes dead subpixels; scroll mode is a pixel-refresher that helps restore freshness on OLED.

Click Fullscreen to start. Use arrow keys (or the Next / Prev buttons) to step through colors. Solid full-screen white or a primary color for 30-60 seconds reveals retention. Press Esc to exit.
Current color
White
Tip: leave the scrolling refresher running overnight to help OLED panels recover from mild short-term image retention. Burn-in that persists after 8 hours of full-screen white is permanent; the refresher will not fix it.

What Is Burn-In?

Burn-in is permanent damage to a display where pixels that have shown the same static content for a long time become dimmer or differently colored than surrounding pixels. It's most common on OLED and plasma panels because each pixel is a separate organic light-emitter that degrades with use. Common culprits: taskbars, news-ticker chyrons, game HUDs, TV channel logos. Modern QD-OLED and WOLED panels are far more resistant than early OLED TVs, but not immune.

Burn-In vs Image Retention

"Image retention" (IR) is temporary — the ghost fades after a few minutes or an hour of normal use. "Burn-in" is permanent — it never fades. This tool can help you tell them apart: run the full color cycle at fullscreen for 10 minutes. If the ghost disappears, it was IR (no real damage). If it's still there after 30 minutes, it's burn-in. For the full fade-or-stay test, the recovery refresher step, and a clear RMA decision tree, see our guide on OLED burn-in vs image retention and how to recover it.

The Scrolling Refresher

Scroll mode displays a moving vertical bar pattern across the whole screen. For OLED panels with mild short-term retention, leaving this running for 4-8 hours exercises every pixel evenly, which can help the dimmer cells "catch up" and reduce the visible ghost. This is essentially what your OLED TV does in its overnight pixel-refresh cycle — but you can force it on-demand through a browser. It won't fix permanent burn-in.

How To Prevent Burn-In

  • Lower OLED brightness when displaying static content (desktop use).
  • Enable pixel shift / orbit features in your TV settings.
  • Use auto-hide for taskbars / docks during long idle periods.
  • Vary your content — rotate through different channels, games, or wallpapers.
  • Let the TV run its automatic pixel-refresh cycle overnight (usually activated by standby mode).

OLED Burn-In Test FAQ

Common oled burn-in test questions

How do I tell burn-in from image retention?

Run the full color cycle at fullscreen for 10-30 minutes. If the ghost fades away, it was temporary image retention. If it remains, it is permanent burn-in.

Does the scrolling refresher actually fix OLED burn-in?

It helps short-term image retention by exercising every pixel evenly. It does not and cannot fix permanent burn-in where subpixel emitters have degraded.

How long should I run the refresher?

Four to eight hours for mild retention. This is similar to what an OLED TV does during its overnight pixel-refresh cycle.

Which content causes OLED burn-in?

Static high-contrast elements displayed for long periods: taskbars, news tickers, game HUDs, channel logos. Varying the content and lowering brightness prevents it.
