OLED Burn-in Test: Free Online Ghost Image Checker
Burn-in is the most common permanent damage on OLED panels. Four professional test modes reveal ghost images on static and moving patterns, help you judge severity — all running locally in your browser, safe and free.
Solid cycle: red→green→blue→white→gray→black — watch high-risk zones for outlines
Why This Burn-in Test
Four Professional Modes
Solid color cycle, sliding bars, checkerboard flip and gradient sweep complement each other: static colors expose outlines, moving patterns expose color shift and trails — far more reliable than a single gray screen.
Works on Every Device
Phones, tablets, OLED TVs, monitors and handheld consoles all supported; touch gestures and TV remote arrows work, and the toolbar auto-hides in fullscreen.
Safe & Fully Local
Everything renders locally in your browser — nothing is uploaded. A 5-minute idle auto-sleep guard ensures the test itself can never burn your panel.
What Is OLED Burn-in? Three Concepts First
Permanent Burn-in
Uneven aging of organic emitters. Long-term static bright patterns (nav bars, logos, HUDs) leave a permanent outline that never fades — irreversible hardware damage.
Temporary Retention
Short-term pixel fatigue causing a reversible ghost that fades within minutes to hours. LCDs show this too — it is not real burn-in.
Mura / Dirty Screen
Manufacturing variance causing cloudy or streaky patches on gray, with no fixed pattern shape — a uniformity issue, not aging.
A Reliable Check in Three Steps
Pick a Test Mode
Enter fullscreen and start with Solid Color Cycle in a dark room — red, green, blue, white, gray and black fill the screen in turn. ←→ switches modes, ↑↓ adjusts speed.
Watch High-risk Zones
Focus on nav bars, status bars, TV logos and game HUD areas — look for outlines darker or tinted compared with their surroundings.
Confirm Across Colors
A ghost visible at the same spot on multiple solid colors confirms burn-in. Then run Gradient Sweep for Mura, and check the verdict guide for the final call.
The Four Test Modes Explained
Solid Color Cycle
Red → green → blue → white → gray (#808080) → black at your chosen speed, showing the color name and HEX live. Ghost outlines have the highest contrast on solid colors — the first gate of burn-in detection.
Sliding Color Bars
Eight spectral bars sweep across the screen at constant speed (direction switchable). Aged areas shift color against the moving bars, exposing even faint burn-in.
Checkerboard Flip
A black/white checkerboard flips at your chosen speed with adjustable cell size. It reveals pixel response inconsistency and trails, and gently evens out pixel fatigue.
Gradient Sweep
A rainbow or black-to-white gradient sweeps smoothly across, amplifying uneven brightness into visible band breaks. Mura, dark spots and dirty-screen effect stand out here.

Burn-in Prevention Guide
Lower the Brightness
Brightness is the biggest aging accelerator. Stay under 70% for daily use, enable auto-brightness, and avoid peak-brightness static content for long periods.
Use Dark Mode
Dark interfaces keep most pixels dim or off, slowing aging dramatically — and auto-hide nav bars, taskbars and other persistent elements.
Auto Sleep
Set a 1–2 minute auto-lock so static images never linger for hours; enable the screensaver and idle power-off on TVs.
Pixel Refresh
Run the built-in Pixel Refresher / panel maintenance of your device regularly (LG, Sony and Samsung all ship one) to compensate pixel aging differences.
Frequently Asked Questions
Daily Care Tips
When buying a used OLED device, always check for logo/nav-bar burn-in with solid colors plus a gray screen before negotiating.
The first 100–200 hours of a new OLED TV age fastest — avoid bright static content especially during this period.
Do not run repair videos for hours to fix retention — 10–30 minutes of this tool’s checkerboard mode is enough.
Keep anti-burn-in features like Screen Shift and Logo Luminance enabled on TVs and monitors.
Mild temporary retention recovers after a few hours of normal, varied content — no need to worry.
Power off instead of leaving a static desktop when unused for long; prefer dark wallpapers.
