General Information

Display Support, made clear:

1x HDMI (Alt Mode): Direct connection to the host GPU via USB C DisplayPort Alternate Mode. Ideal for video playback, general applications, and low latency use.

2x HDMI (DisplayLink): USB-based graphics for extending additional monitors even on systems that natively support only one display (like M1/M2 Macs). Great for office tasks, web use, and productivity workflows. Not recommended for high frame rate video, 3D design, or gaming.

Built for Deployment

This DisplayLink docking station for multi-monitor support is tested across Dell, HP, Lenovo, and Apple MacBooks and is ideal for organizations standardizing across mixed fleets.

Systems with ASMedia USB 3.1 controllers (do not support Alt Mode)
