There have been issues identified between DisplayLink powered USB video adapters and docking stations with macOS 10.13.4. At this time these products are incompatible with macOS 10.13.4. DisplayLink, a third party company that manufactures chipsets, is currently working on ways to address the issue identified in the current macOS release. StarTech.com is monitoring the situation and we will update our information as it becomes available.
If a system has updated to 10.13.4, reinstalling 10.13.3 or earlier is an option for advanced users to restore DisplayLink functionality: Revert to a previous macOS version.

You can use an external display or projector with a Mac notebook while its built-in display is closed. This is known as "clamshell" or "closed display" mode.
Clamshell mode requires that the following devices are connected to the Mac notebook:
- A power adapter.
- An external keyboard, mouse, or trackpad.
- An external display.
macOS does not see DisplayLink displays as external displays, therefore this criteria is not met and clamshell mode cannot be enabled when a DisplayLink adapter is the only external display connected to the computer.

Ethernet Connection
To test your setup components, try the following:
-
Use the video cables, video source, video destination, laptop docking station, USB peripherals, and Ethernet connection in another setup to see if the problem is with the components or the setup.
-
Use a different video cable, video source, video destination, laptop docking station, USB peripherals, and Ethernet connection setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.
When you test your cables, it is recommended that you do the following:
