macOS: Only mirror functionality can be used on external monitors. The external monitors will always mirror the content shown on your notebook screen. To use with multiple monitors a different i-tec video adapter must be used.
The adapter is an excellent choice for designers, graphic designers, gamers, and other users working with more than one screen.
Use is very simple - plug the adapter into the USB-C or Thunderbolt 3 port on your computer, connect the HDMI cables, and immediately start using two monitors. Driver installation is automatic from the system.
