NOT macOS COMPATIBLE (10.13.4 version and later) The Plugable UD-ULTCDL USB-C Docking Station provides up to three additional display outputs via a combination of USB-C DisplayPort Alternate Mode (“Alt Mode”) and DisplayLink USB graphics. Up to 60W via USB-C Power Delivery (“PD”) to charge your host computer, Gigabit Ethernet, audio, and 6x USB device connectivity. All through a single USB-C cable.

See important notes regarding Alt Mode and PD compatibility below.

Graphics Performance

Main HDMI port utilizes USB-C Alt Mode which has a direct “pipeline” to the host graphics processor (GPU), and connected monitor will perform as if natively attached. The 2nd and 3rd outputs are powered by DisplayLink DL-3900 which leverages the host GPU & CPU; these outputs are not recommended for gaming.

Alt Mode and PD Compatibility

Alt Mode video supported on select systems including Dell XPS 9350, 9360, 9550, 9560, Dell Precision 5510, HP Spectre 13″ x360 13t. The included power supply can charge compatible host systems with up to 60 watts of PD power. Charging speed is host dependent but behaves as if laptop/tablet were connected to it’s stock charger.

DisplayLink graphics require Intel / AMD / NVIDIA GPU and driver.

Cannot be mixed with non-DisplayLink USB graphics adapters and drivers (e.g. MCT, j5, or SMSC). HDCP/Blu-ray playback not supported.

Incompatible Systems

NOT macOS COMPATIBLE (10.13.4 version and later). Most current phones & tablets with USB-C ports do not support Alt Mode video output. ASMedia USB 3.1 controllers do not support Alt Mode at this time.
