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.
