Temporary image retention
A recent static image may leave a faint afterimage that diminishes with rest or ordinary varied content. Only time and a later recheck can distinguish that behavior; do not deliberately create retention to test it.
Short-run visual inspection
OLED burn-in and uniformity check
Use brief, deterministic fields to look for persistent shapes, temporary retention, uneven gray, dirty-screen effects, and point-like pixel anomalies. This is an observation aid, not a hardware diagnosis or repair.

Ready. The display is on a dim rest screen; no pattern starts until you choose one.
Choose a short pattern
Start with gray fields, then use color only to inspect a point-like anomaly. Selecting a pattern restarts its bounded timer.

How to use
- 1
Prepare normally.Clean the screen gently, use typical viewing light and distance, keep normal brightness, disable neither pixel shifting nor other panel care, and let the panel finish any routine it already started.
- 2
Scan gray briefly.Check 5%, 15%, 30%, and 50% gray for shapes that stay fixed in the same place. Very dark OLED gray can look naturally uneven.
- 3
Use movement for context.The checker can reveal broad nonuniformity; the moving band can make dirty-screen effects easier to notice. Reduced-motion preferences keep that band still.
- 4
Recheck later, not repeatedly.A mark that fades after normal varied content or rest suggests temporary retention. A persistent mark deserves a source check and manufacturer guidance; this page cannot confirm burn-in.

Record what you observed
These notes offer cautious context only. Select every statement that fits; “nothing obvious” clears the others.
No observations selected. A short browser check can reveal things to investigate, but it cannot certify panel condition.
What the patterns can, and cannot, suggest
Permanent burn-in
Differential subpixel aging can leave a persistent recognizable shape. Persistence across fields and input sources can be consistent with burn-in, but a browser cannot prove the cause or permanence.
Uniformity variation
Broad tint, vertical bands, or cloudy areas, especially on dark gray, may reflect panel uniformity, compensation state, viewing conditions, or signal processing rather than a retained image.
Dirty-screen effect
Fixed mottling or bands that become conspicuous behind moving, low-detail content are often described as dirty-screen effect. The moving gray band is a visual aid, not a measurement.
Dead or stuck pixel
A point that remains dark, bright, or one color across several fields may be a pixel anomaly. Dust, scaling, browser zoom, subpixel layout, and content rendering can mimic one; this test cannot map panel-native pixels.
Next step
Confirm with another source and normal content. If a concern persists, use the model's built-in picture test and follow its manual or support channel. Do not repeatedly run manual panel-refresh routines unless the manufacturer specifically directs it.
Measurement and browser limits
The percentages here are deterministic sRGB code values, not measured luminance. Browser color management, HDR/SDR conversion, operating-system scaling, zoom, panel processing, ambient light, viewing angle, and automatic brightness limiting all affect what reaches your eyes.
- No web page can certify permanent damage, panel age, physical pixel state, hardware safety, or warranty eligibility.
- This is not calibration and does not reproduce laboratory image-sticking or pixel-defect standards.
- The page does not perform pixel refreshing, compensation, repair, burn-in removal, or device control.
- Fullscreen reduces distractions but cannot guarantee native-pixel mapping or hide every browser or operating-system overlay.
