Bit depth, chroma and DSC for HDMI and USB-C are not stated. The manual's Type-C Bandwidth setting limits USB 3.2 mode to 3840 x 2160 at 120 Hz, so the USB-C maxima need the other bandwidth setting.

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.
