Universal Docking Station

The ALOGIC DUCDV4 connects up to four external displays through three HDMI and one DisplayPort output for expanded workstation space. It also functions with older laptops via USB-A, supporting up to two screens in that configuration.

Thermal and Power Behaviour

The dock draws 15 W from the attached USB Power Delivery adapter to run its own circuitry and any connected peripherals. Remaining power is passed through to the host computer, keeping the unit cool and quiet during typical office workloads.

100 W Power Delivery Input

A USB-C PD power supply rated at 100 W is required to deliver maximum charging performance to the laptop while driving four displays. Lower-rated adapters will limit both dock operation and host charging speed.

Questions about this item

How do I install the ALOGIC DUCDV4 dock and what step is often missed?

Connect the dock to the laptop via USB-C or USB-A, attach up to four displays using the three HDMI and one DisplayPort outputs, then connect a USB PD power supply (not included) to the dock's power input so the dock reserves 15W and passes the rest to the laptop.

What maintenance or replacement will the ALOGIC DUCDV4 dock need later?

The dock itself has no user-serviceable parts; only the external USB PD power adapter may need replacement if it fails or if a higher-wattage unit is required for faster laptop charging.

What limit appears first on the ALOGIC DUCDV4 dock during sustained heavy use?

The dock reserves 15W for its own operation and peripherals, so the power passed to the laptop is capped by the connected USB PD adapter's rating minus that 15W overhead.
