If you went to the link, perhaps your question would've been answered.We shall see if they have inventory? Does it have HDM2.1?
Yes, claiming 7 in, 3 out; full 4k/120, 8k/60 support.
One source reported full 48Gbps speed, which would indicate 3rd gen chipsets, I think. This is only hearsay: I could not find anything about that when I searched last night.
