A similar argument might be said about "displays over display-port" or "displays over VGA".
If you "wouldn't wish this on anyone", would you mind sharing why? If suppliers aren't complying with the spec, or the spec is inadequate, I would like to understand why.
DisplayLink is pretty awful. Especially on macOS, due to limitations of macOS, they are laggy, don't display certain apps correctly and more.
There are quite a few docks out there (I know Asus had one) that use DisplayLink technology to show external displays.
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.
Dell sells one that is pretty good and used by a lot of my friends.
