Frequently asked questions
Do OLED panels need different checks than LCD?
Yes. True black, near-black uniformity and image retention behave differently on OLED, so this inspection focuses on them instead of backlight-only checks.
Can one session detect burn-in?
It helps you observe retention and uniformity right now. Burn-in develops over long-term use, so a single session cannot prove or rule it out.
Should I dim the room for the OLED checks?
Dim lighting makes near-black fields easier to judge. Keep the lighting consistent between checks so your observations stay comparable.
