Is he sure, that both chips are full-fledged HDMI 2.1 chips?
Maybe one of those chips is still a HDMI 2.0b Chip.
To quote myself: According to LG Germany the C9 does not support
just yet. This feature should be available in a future firmware update this year.
I do not no if this goes for all models. Or only for the german version of the C9 (and E9 etc.).
But I think it goes for all versions.
Anyway, maybe their HDMI 2.1 "software" (or however you want to call it) is not ready
while the hardware is. So maybe they went with a HDMI 2.0b chip and a HDMI 2.1 chip.
So they could release the C9 early on without native support for HDMI 2.1. But later on they are
going to "active" the HDMI 2.1 chip?
This could also explain why some LG subsidiary are talking about HDCP 2.2 instead of HDCP 2.3 (In contrast: LG AUS mentions HDCP 2.3 for [email protected]
; which presumably is not available yet).
Maybe Vincent will give us some more information in his upcomming review.
