Here's a more extensive walkthrough of how the Samsung Galaxy Note 9's built-in DeX functionality works with an HP Elite X3 Lap Dock. This Lap Dock was designed for a Windows Phone using Continuum to enable certain apps and services to extend to the lap dock screen, keyboard and trackpad. It works quite well for native Google apps but third party applications like Netflix and Instagram do not scale the whole size of the screen.
The HP Elite Lap Dock also doesn't seem to work with other USB Type-C devices (it didn't work with a MediaTek processor powered Planet Computers Gemini or a Microsoft Surface Go). I no longer have my Note9 review unit so I cannot test functionality on the Lap Dock any further, but it was interesting to see how much of it did work.
