I'm no video expert, so correct me if I'm wrong, but I thought you can do 3840x2160@60Hz video with 24bit/pixel with under 14.4Gbps, which is the HDMI 2.0 limit

I'm no video expert, so correct me if I'm wrong, but I thought you can do 3840x2160@60Hz video with 24bit/pixel with under 14.4Gbps, which is the HDMI 2.0 limit [0]. According to this [1], that signal would require 12.54Gbps, so with a link budget of 34.56Gbps - 2*12.65Gbps, you'd have about 9.48Gbps left over for USB and ethernet (which is on the PCI bus for this particular hub). I suppose these numbers include coding overhead for the physical link, but I can't say for sure. If you wanted more than 60Hz or more than 24bit/pixel, you'd definitely run out of bandwidth with two monitors and USB/ethernet.
