Cannot use Clamshell mode on macOS

Clamshell mode (working with lid closed) is supported for DisplayLink displays on macOS Mojave 10.14.

We are aware and currently investigating the change in behaviour of clamshell mode in macOS Catalina 10.15.

On earlier versions of macOS, DisplayLink displays are not recognized as additional displays by the OS and Clamshell mode cannot be used with DisplayLink.
