Am I able to use clamshell/closed display mode with this adapter in Mac OS?

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.
