Factory default mode at brightness 100%, using an SDR 100% white APL field, gives 292.3 cd/m². The peak-brightness setting is not separately named for this default result. Tests followed about two hours at maximum brightness in a 25°C room. Instruments are a Konica Minolta CA-410 with CA-VP427 probe and an X-Rite i1 Basic 3 Pro Plus. The later 307.9-nit ABL experiment is a different condition.
