Indeed, I'm talking about DisplayLink.
I wish I could plug my 2 screens and the ethernet cable directly into the macbook. However, since Apple decided 2 USB-C port is enough, I'm left with a pretty crappy dock that don't even send power through the port. Hell, I can't even plug a tv screen into the laptop without a dongle (no HDMI).
This is absolutely infuriating. Don't buy this crap.
