Works great. Bought to drive a Displayport monitor and a DVI-DL monitor. I connected a displayport to minidisplayport adapter to the onboard port and then connected an Apple DVI dual link adapter to it and it works great. I'm using a second Thunderbolt port to drive a second 4k display (using this: USB-C Cable to DisplayPort 4k @ 60Hz Adapter, 5.9ft 1.8m, QGeeM USB 3.1 TYPE C Adapter to Displayport adapter, 4K HDTV support, for Macbook Pro 2016 2017, ChromeBook, Pixel, Dell XPS Sumsang S8 Galaxy Note 8 etc.) Everything works great! Didn't think I'd use it, but the USB charging port on the front is very handy. It also doesn't charge your laptop, but it does keep my 13-inch MBP from draining too quickly. Notes: Ethernet is NOT required. Drivers in OSX 10.12 as far as I know. So yes! Plug it in and it works! Can't complain at all.
