These are visual browser checks, not manufacturer certification, professional calibration or repair diagnosis.
A focused five-step check
- 01
Use your normal brightness and picture mode.
- 02
Inspect red, green, blue and low-grey fields for persistent silhouettes.
- 03
Check 5%, 10% and 50% grey for tint and uniformity.
- 04
Play varied normal content, then revisit any faint retention.
- 05
Avoid leaving static test patterns on screen longer than needed.
GOOD TO KNOW
AnHot does not offer a “burn-in fixer” and cannot distinguish temporary retention from permanent wear.
