Normally I wouldn't even post an adapter purchase, but this one is kind of hard to get and pricey due to it "SUPPOSEDLY" being the only Displayport 2.0 -> HDMI 2.1 adapter in existence. This is in fact however, a lie, at least as most of us would think of it.
It does support several of the niceties of Displayport 2.0 such as dynamic HDR metadata and such, which is probably why legal let the "DP 2.0" naming fly. but it's not a full bitrate DP 2.0 adapter. It's not even a minimum bitrate DP2.0 adapter. It's honestly more of a DisplayPort 1.4 adapter. It is however still, the fastest adapter I have ever tested, clocking in at HBR3 speeds of 8.1gbps x4 lanes. That's fast, but it isn't really true Displayport 2.0 fast. Most adapters do not surpass HBR2 which is Displayport 1.2 speeds.
Proof:
Proof: That's HBR3 speeds when rendering 4k@120hz Full RGB 10bpc, which while no adapter anywhere else I have tested goes beyond HBR2, still falls short of any UHBR speed and still means DSC will be used on a 4k@120hz 10BPC HDR link. Can't deny I feel somewhat disappointed. Hope this helps someone.
@W1zzard don't suppose you know the technical requirements to label a active adapter as DP 2.0 compliant, and if just supporting HBR3 is violating them? Caldigit is a fairly high end "Mac user" retailer so this fairly blatant misuse of the terminology surprised me a bit.
