With the iPad Professional with this dock, can it present simultaneous 4K 60Hz and USB 3? Or is it restricted to USB 2 speeds on this setup?
No you can’t as a result of the iPad Professional has a bandwidth limitation of 10Gbs. Due to this fact, not sufficient to assist twin 4K at 60hrz.
I’ve observed there don’t appear to be any USB-C hubs available on the market, simply docks.
USB-C hubs are restricted to the ability of your BUS. 15 watts is not sufficient to ship energy to assist show and all of the ports on the hub. For a product to be licensed by Thunderbolt Three all of the ports on the dock should work contemporaneously. Nevertheless, a hub is just not a Thunderbolt Three gadget and doesn’t have this requirement. For those who do get a hub, then watch out about utilizing various ports. With out the correct quantity of energy chances are you’ll undergo information loss, or a lot worse.
