So is there a less 'modern' way of supporting displaylink without this application, a legacy driver? I can't believe that there was never a way to run displaylink screens in clamshell mode back in 2014 when this device was new?

Prior to the current implementation of the DisplayLink Manager Application, the DisplayLink driver used a kernel extension in order to provide its functionality. This approach was deprecated by Apple in macOS 11 Big Sur, hence the creation of the new App.

If your Mac was running macOS 10.15 and running the legacy version of the DisplayLink driver, you would be able to use clamshell mode.

Well I was going to go to a lot of effort to use a hack to upgrade my Mac OS to a newer unsupported version using opencore, but glad I tried the obvious solution before going to all that hassle.

For anyone else who finds themselves with this issue - all I did was uninstalled the latest version of the displaylink manager application and then installed the legacy release:

DisplayLink USB Graphics Software for macOS
Catalina 10.15, Mojave 10.14
Release: 5.2.6

Rebooted, allowed screen recording permission and all is working perfectly on BigSur 11.7.10

Hope this helps someone else.
