The USB3 monitor docking stations are a mixed bag, so I understand why you would have had trouble with one. Driver-wise, it's important to remember that they're all just DisplayLink adapters so I just go get whatever is the latest driver at the http://www.DisplayLink.com site. Anyay, I got this one a while back and was happy with it, though I'm sure there are even better ones now: https://www.amazon.com/gp/product/B006ZGWJU2/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Note that it has an HDMI and a DVI plug, which you complained about specifically: I just had the necessary cables so that I could drive both my external monitors of of those two plugs directly (HDMI plug to DVI plug is just a cable with different endings, not a converter of any kind).

I don't know anything about USB-C monitor connections. I wonder if it's one of those things where, you just need a USB-C hub and some USB-C-capable monitors; i.e., direct-plug-USB monitors, as opposed to HDMI/DP/etc? Dunno.
