My understanding is that the problem with high bandwidth/resolution setups over displayport (which may not be your use case) is in your mac, not in your hub. Older comment thread here https://news.ycombinator.com/item?id=29214726
I'm totally not suprised by this. I'm using USB-C between the hub and the monitor, and that seems to be working fine, so I basically haven't thought too much about it.
