Exactly why I'm perplexed when people are able to install USB drivers for MacBook Air's to be able to drive 2 displays one over DP & the other over USB somehow after a driver software is installed

There's a product called DisplayLink that's used with certain USB monitors and USB docks. It compresses the video displayed on the screen in a userland daemon.

It requires Synaptic's software and it does work as a solution for devices that don't have enough I/O capacity to support multiple DisplayPort screens.

They use that at work on some of the freeze seating places.

It's quote buggy and resource hungry on macos and didn't play nice at all on my Ubuntu.
