OLED burn-in inspection
Inspect persistent image retention using neutral and primary-color fields.
Diagnostic visuals retain their original colors and remain visible. Presentation filters and high contrast apply outside this workspace; device-level filters may still affect your observation.
Compare gray, low gray, white, black, red, green and blue at normal brightness. Record visible retained shapes.

Understand the result
PASS describes a received signal or your recorded observation. WARNING calls for another check. USER REVIEW REQUIRED means a measurement alone cannot decide. An unavailable API or denied permission does not establish hardware failure.
What this cannot tell you
Visual inspection only. The browser cannot automatically detect OLED burn-in or promise repairs.
If something seems wrong
Compare different images and normal viewing conditions; consult manufacturer support for persistent retention.

Is anything uploaded?
Raw diagnostic input and media are processed locally. Standalone results remain in page memory. Guided checks offer optional coarse session recovery for 24 hours; it excludes media and detailed measurements. Hosting and Google Analytics requests still leave your browser. Analytics receives only broad test-usage categories, never these diagnostic contents. See the privacy policy.
Does a pass guarantee my hardware is healthy?
No. It records behavior observed in this browser session. Intermittent faults, internal components and operating-system restrictions need further investigation. See our methodology.
