Operating Instructions

Display Configuration

The docking station supports various display modes depending on your operating system.

Windows Systems (DP1.4 Source)

For Windows laptops with a DP1.4 source, the docking station supports Mirror Mode (A-AAA) and Extend Mode (A-BBB, A-BCD) across up to three external monitors (2x HDMI + 1x DisplayPort), with each display supporting up to 4K@60Hz.
