5. Operating Instructions

5.1. Windows Display Settings

For Windows laptops with DP1.4, the docking station supports various display modes:

• Mirror Mode (A-AA): All connected displays show the same content as your laptop screen.
• Extend Mode (A-BB): Your laptop screen and one external monitor show different content, while the second external monitor mirrors the first.
• Extend Mode (A-BC): Your laptop screen and both external monitors display different content, creating a triple extended display setup.

To configure display settings in Windows:

1. Right-click on your desktop and select "Display settings" or go to "Settings" > "System" > "Display".
2. Under "Multiple displays", you can arrange your displays and choose between "Duplicate these displays" (Mirror Mode) or "Extend these displays" (Extend Mode).
