Dead Pixels vs. OLED Burn-in: What’s the Difference?

You see a faint shadow of a logo or a health bar. Is it burn-in, image retention, or just a cluster of stuck pixels? Diagnosis matters because fixes and warranties differ.

Test your screen now - use white/black for sharp dots and gray/dark red for ghost shapes, then compare photos to confirm burn-in vs pixel defects.

Quick Answer

  • Sharp dot (black or bright): pixel defect. Test on solid white/black with our dead pixel tester.
  • Faint ghost shape: likely image retention or burn-in. Test on gray/dark red.
  • Temporary retention can fade; burn-in is permanent aging.

Dead/Stuck Pixels vs. Burn-in

  • Dead pixel: Transistor failed; black dot on white.
  • Stuck pixel: Sub-pixel jammed ON; bright dot on black.
  • Burn-in / Retention: Region of pixels aged unevenly, leaving a shadow. Looks like a blurred watermark, not a dot.

How to Test Correctly

  • For pixels: use solid White and Black. Zoom phone camera to 3–5× if needed.
  • For burn-in: use 50% Gray and Dark Red; ghosting shows best there.
  • Run tests fullscreen: HardwareTest.org/screen-test.

Common Triggers for Burn-in (OLED)

  • Static UI (news tickers, game HUDs, channel logos).
  • Always-on taskbars/docks at max brightness.
  • High brightness for long hours, especially with static content.
  • Kiosk/demo loops that never change layout.

Retention vs. Burn-in: How to Tell

  • Image retention: Temporary, often disappears after 10–60 minutes of varied content or a panel “pixel refresh.”
  • Burn-in: Persists after rest and pixel refresh; visible across backgrounds (gray/dark red).
  • Tip: Power off for 30 minutes, then retest on gray. If it fades, it was retention.

Can You Fix It?

  • Dead/stuck pixels: Stuck may recover with flashing; dead are permanent.
  • Burn-in: Permanent material aging. Pixel refresh can reduce severity but won’t restore original uniformity. Early intervention (lower brightness, vary content) can slow further damage.

Prevention Playbook

  • Enable auto-hide taskbars/docks; use dark mode where appropriate.
  • Rotate static layouts (change HUD positions if games allow).
  • Reduce OLED brightness for static work sessions; use screen savers.
  • Run manufacturer “pixel refresh” on OLED TVs/monitors as recommended (often after long sessions or automatically in standby).

When to File a Claim

  • Check brand-specific burn-in terms (TVs vs. monitors differ). Some gaming OLEDs now cover burn-in for limited years; many consumer monitors do not.
  • Provide photos on gray and dark red. Note hours on the panel and typical usage (static vs. varied).

Special Cases

  • LCD image retention: Rare but possible on some IPS/VA; usually fades after rest.
  • VA glow/IPS glow: Edge brightness on black screens is not burn-in—test on gray.
  • Uniformity issues from backlight bleed: Visible on black, not on gray as a shadow of UI; different problem.

Bottom Line

  • Dots → pixel issue. Shadows → retention/burn-in.
  • Confirm with the right backgrounds.
  • Prevent by reducing static content + brightness, and test periodically with gray/dark red on the screen test.
