Single-cable expansion for dual-monitor laptops

The U342-DHG-402 connects to one USB 3.0 port on a laptop and adds HDMI, DVI-I, stereo audio, four USB 2.0 ports, two USB 3.0 ports and a Gigabit Ethernet jack. It draws power from an included 5 V, 4 A adapter that accepts 100-240 V input. The dock measures 7.40 by 1.20 by 3.00 inches and weighs 1.30 lbs. It is intended for users who need two external displays and extra peripherals from a single host connection.

Replaces separate video adapters and USB hubs

Instead of carrying an HDMI dongle, a DVI adapter, a USB hub and a wired network dongle, this dock consolidates every connection into one USB 3.0 link. The jump is worth it when a laptop has only one high-speed port but the workspace demands dual monitors, wired internet and several accessories simultaneously. Backward compatibility with USB 2.0 and 1.1 means it still functions on older ports, though at reduced throughput.

Steady throughput for long sessions

USB 3.0 supports data rates up to 5 Gbps, so sustained file transfers, video playback and network traffic remain stable across the two USB 3.0 and four USB 2.0 ports during extended use. The external power supply keeps bus voltage constant, preventing the port-power drops that cause disconnects on bus-powered hubs. Driver support for Windows 7 and later, macOS 10.8.5 and later and Ubuntu 14.04.2 ensures consistent behaviour across operating-system updates.

Questions about this item

What size clearance does the 7.40" x 1.20" x 3.00" dock need on my desk?

The unit measures 7.40 inches wide, 1.20 inches high and 3.00 inches deep, so allow at least that footprint plus room for the 6 ft power cable and the USB 3.0 host cable.

Which driver must I install before plugging the USB 3.0 A male connector into my laptop?

Install the DisplayLink driver for your OS — Windows 7 or later, macOS 10.8.5 or later, or Ubuntu 14.04.2 — then connect the dock; the driver enables the HDMI, DVI, audio, Ethernet and hub ports.

When should I replace the external 100-240V 0.8A 5V 4A power adapter?

Replace the adapter if the dock loses video on both monitors, USB ports stop charging, or the Ethernet link drops while the laptop remains powered.
