Burn-in Test

Inspect solid-color and moving patterns for retention-like artifacts without claiming that an artifact is permanent.

Before you start

Step-by-step instructions

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

Inspect retention-like artifacts across several patterns; this test cannot prove permanence.

Persistent-Looking Shape

Record repeated real-world visibility; this illustration cannot prove permanent damage or cause.

Changing Shape

A change is useful to record, but duration alone cannot diagnose whether an artifact is temporary or permanent.

No Retention

No retention-like shape was visible in the patterns reviewed.

It fades or changes after ordinary content: Record the change and recheck later with the same brightness and display mode. The change does not prove a cause.
It remains in the same physical location: Compare several colors and repeat the check later. Persistence is worth documenting, but this page cannot prove permanent damage.
It looks more like a line, tint, or broad patch: Use the uniformity test to separate a screen-wide variation from a content-shaped artifact.

Use only panel-care features documented by the manufacturer. A browser pattern cannot promise a repair or decide support eligibility.

No retention-like shape noted in the patterns I checked.: Return to ordinary content. Keep this as a baseline and recheck only if the original shape appears again.
A similar shape stayed in the same location across colors.: Note the shape, location, colors, and time. Use ordinary content and recheck later under the same conditions; check the manufacturer panel-care instructions if it persists.
The shape changed or became less visible during my recheck.: Record the elapsed time and what content ran between checks. Repeat later without treating a temporary change as proof that the panel is repaired.
Retention was not assessed / I am not sure.: Compare one neutral gray and a second solid color briefly. A pattern appearing only within the test drawing is not evidence of a retained image.

This test cannot determine permanence, cause, severity, or warranty eligibility.

Record the color and screen location where a shape remains visible, then recheck later with ordinary content.
The saved record identifies the last pattern and, for solid-color inspection, its displayed color. Pattern coverage does not establish whether a retained shape is permanent.
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.

Setup and sources

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.
