Correct, there is only 5Gbps of bandwidth and 4K@30Hz uses more than that for uncompressed streams. Compression gets it a bit under, but unless they went to USB3.1 Gen2, there just isn't enough bandwidth for higher resolution or refresh rates.
Does it do HDMI through DP alt mode and a converter, or some software-requiring USB-to-HDMI adapter shenanigans? I suppose the resolution support would point to the latter. A shame, really.
Why, oh why, is it only 5 Gb/s 3.0? Why not 10 Gb/s 3.1rev2? That would then give the alternate-stream bandwidth for full 4K/60. Plus, you know, current standard.
I *AM* impressed that this appears to be the first USB-C dock that actually has a *data* USB-C port on it, not just a power-input port. Every other frickin' USB-C dock has just the computer connection and the power port, no other USB-C ports. I understand the usefulness of adding USB-A ports to MacBook/MacBook Pro computers, but having a future-oriented USB-C port would be nice, too, for people who actually have started getting USB-C cables. (Like a USB-C Lightning cable for connecting iPhone or Magic Trackpad to recharge,
Lol wat, related items on amazon are all < $50, most around $20-30 why the fuck would anyone buy this shit from Kingston. It doesn't offer anything that all the other shit doesn't already do.
And for those whining about 4K/60, just use the second USB-C/DP Altmode port for video and one for USB/ethernet hub.

I cannot find it anywhere, is the sd card reader UHS-II compatible?lurker22 - Wednesday, January 17, 2018 - link
So close. Shame they cheaped out and maxed output of 4k @30hz using HDMI v1.4.lmcd - Wednesday, January 17, 2018 - link
I think they're already using most of the bandwidth available.jordanclock - Wednesday, January 17, 2018 - link

Power delivery can be tricky with these devices. I try multiple devices on multiple computers and I found best to go with brand of computerIE
Dell XPS 13 2in1 use Dell Docking station
Samsung TabPro S using Samsung dock
I have an Atom based Windows 10 device - with USB-C - forget it.
