Burn-in Test
Inspect solid-color and moving patterns for retention-like artifacts without claiming that an artifact is permanent.
This check opens a focused test surface. You can return with Escape. Review what this browser test can and cannot measure.
Before you start
- Clean the screen and use your normal viewing brightness.
- Let ordinary content play first so you have a current visual reference.
How to run this check
- Start the Burn-in Test
- Cycle through the solid-color, gray, grid, and moving patterns
- Look for faint shapes or discoloration that remain in the same screen location
- Record the pattern, color, and location of anything visible
- Recheck later with ordinary content; this test cannot prove whether an artifact is permanent
What this browser test can tell you
Can help you check
- Visual inspection for persistent-looking retention patterns.
Cannot measure
- This test cannot determine permanence, cause, severity, or warranty eligibility.
Setup, interpretation, and sources
Recommended setup
- Clean the screen and use normal viewing brightness in a dim room.
- Inspect several solid colors and neutral gray without staring at one frame for too long.
How to interpret what you see
- Record the color and screen location where a shape remains visible, then recheck later with ordinary content.
- Browser-rendered colors, operating-system display mode, brightness controls, color management, and panel protection features can change what is visible.
- Objective persistence measurements require a calibrated imaging system or luminance meter.

💡 Why This Test?
This test displays solid colors, neutral grays, grids, and moving patterns to help you notice shapes or discoloration that remain in the same screen location. It can document a retention-like artifact, but one browser session cannot prove that the artifact is permanent burn-in, identify its cause, or determine warranty eligibility.
✅ What You'll Check:
- Shapes that remain visible across several colors
- Retention-like artifacts that change after ordinary content
- Uneven-looking color or brightness
- Common problem areas (corners, status bars, logos)
- Color shifts in affected regions
📖 How to Use This Test
- Use normal viewing brightness and clean the screen before testing
- Click "Start Test" to enter fullscreen mode
- Navigate through 6 test patterns using arrow keys or buttons
- Look for ghost images, shadows, or discoloration on solid backgrounds
- Test red, green, blue, white, and neutral gray
- Record the pattern, color, and screen location of anything visible
- Recheck later with ordinary content before drawing conclusions about permanence
Tip: Browser-rendered colors, operating-system display mode, brightness, color management, and panel protection features can change what is visible. Use the shared methodology above when interpreting an observation.
Inspect retention-like artifacts across several patterns; this test cannot prove permanence.
🔥 Retention-Like Artifact Illustrations
Artifact Remains Visible Across Content
Record repeated real-world visibility; this illustration cannot prove permanent damage or cause.
Artifact Changes Over Time
A change is useful to record, but duration alone cannot diagnose whether an artifact is temporary or permanent.
No Artifact Noted
No retention-like shape was visible in the patterns reviewed.
📺 Risk by Display Type
💡 Prevention Tips
- • Use screen savers or sleep mode
- • Avoid static content for long periods
- • Lower brightness when possible
- • Enable pixel shift if available
- • Vary content regularly
📋 How to Test
Start Fullscreen Test
Launch the test in fullscreen for complete coverage check.
Check Solid Colors
Look for ghost images or uneven areas on solid backgrounds (red, green, blue, gray).
Test Patterns
Use checkerboard and grid patterns to inspect localized retention-like shapes.
Animation Test
Use moving patterns to compare whether an artifact remains in the same location; this cannot distinguish temporary retention from permanent burn-in.
Document Issues
Note the location, color, and appearance of any retention-like artifact observed.

🔧 Common Issues & Solutions
👻 "See faint ghost logo/taskbar that fades away after 5-10 minutes"
What you observed: A faint retention-like shape was visible and later became less noticeable. That change is useful to record, but a browser pattern cannot determine the artifact's cause or prove whether it is temporary.
How to interpret it: Recheck the same location later with ordinary content and the same brightness and display mode. Browser-rendered colors, panel protection features, image processing, and viewing conditions can change how visible the shape appears.
✅ Next step: Follow the display manufacturer's documented maintenance guidance. If the artifact persists in ordinary content, record it and consider professional or manufacturer evaluation.
🔥 "Logo, taskbar, or game HUD shape remains visible"
What you observed: A retention-like shape remained visible across more than one pattern or during ordinary content. The browser test cannot prove permanence, diagnose uneven pixel degradation, or establish the cause.
How to interpret it: Record the affected colors, location, display settings, and whether the shape remains visible after normal varied content. Persistence across repeated checks may warrant professional evaluation, but it is not a browser diagnosis.
✅ Next step: Use the manufacturer's support and maintenance guidance, preserve your observations, and seek qualified evaluation if the artifact continues to affect normal content.
🌈 "Pink/green tint where taskbar was" or "Uneven color on solid backgrounds"
What you observed: A color tint or shape appeared in a repeated screen location on one or more solid backgrounds. Browser-rendered colors, OS and display color processing, viewing angle, uniformity, retention, or other hardware conditions may contribute; this page cannot diagnose subpixel aging.
How to interpret it: Record the color, pattern, location, brightness, and display mode, then recheck with ordinary varied content. A browser observation cannot calculate color error, identify wear, or prove permanence.
✅ Next step: Follow the manufacturer's documented maintenance guidance. If the tint remains visible in ordinary content, preserve the observations and consider manufacturer or professional evaluation.
📏 "Vertical bands or lines on solid gray/green backgrounds"
What you observed: Vertical lines appeared on one or more browser-rendered solid backgrounds. Browser and OS processing, color management, viewing angle, brightness, display uniformity, or other hardware conditions may affect the appearance.
How to interpret it: Record the affected color, location, brightness, viewing position, and whether the lines remain visible in ordinary content. This test cannot determine cause, severity, warranty status, or whether the observation is normal for the device.
✅ Next step: Use the manufacturer's documented support and maintenance process. Persistent real-world visibility can justify qualified evaluation.
💻 "A ghost-like shape remains visible on an LCD"
What you observed: A retention-like shape appeared on one or more solid backgrounds. Browser-rendered colors, viewing angle, display processing, temporary image persistence, uniformity differences, or other hardware conditions could contribute; this page cannot identify which one.
How to interpret it: Recheck the same location with ordinary varied content, the same brightness, and a centered viewing position. Duration alone, including visibility beyond 24 hours, cannot prove permanence or cause.
✅ Next step: Preserve the observation and follow the manufacturer's documented guidance. Persistent symptoms in normal use can justify manufacturer or professional evaluation.
