Triple display docking station

The ALOGIC USB-C Triple Display Docking Station expands a single USB-C port into two DisplayPort outputs, one HDMI port, multiple USB connections, Gigabit Ethernet, audio and an SD card reader. It delivers up to 100W of power to charge the host laptop while driving three external 4K displays in extend or mirror modes on Windows, or mirror mode on macOS.

Check host port and display limits

Verify that the laptop USB-C port supports DisplayPort Alternate Mode and power delivery input, otherwise video and charging will not function. The number of active 4K screens depends on the host graphics capability, so consult the manufacturer resolution table before connecting three monitors. Total USB bandwidth is shared across the two 10Gbps USB-C and two 5Gbps USB-A ports.

Replaces single-port hubs and basic adapters

This dock supersedes simple dongles that offer only one video output or lack laptop charging, consolidating power, triple-display connectivity, wired networking and peripheral expansion into one device. The upgrade is worthwhile when a workstation requires simultaneous multi-monitor productivity, high-speed data transfers and reliable Ethernet without juggling multiple adapters.

Questions about this item

What cables and accessories come in the box with the RNAB08QVCRMH3, and do I need to buy anything extra for the displays?

The dock arrives with its own power supply and a host cable to link the single USB-C port on your laptop; video cables for the two DisplayPort and one HDMI outputs are not included, so have those ready for each monitor.

How do I decide which of the three video outputs to use for my 4K screens?

All three outputs — two DisplayPort and one HDMI — can drive 4K resolution; choose DisplayPort when your monitor has that input for the most straightforward connection, and use HDMI for the third display or a TV.

Will the 100 W power delivery actually charge my laptop while every port is in use?

Yes — the dock passes up to 100 W to the host over USB-C, so a compatible laptop charges at full speed even while you run three 4K displays, Ethernet, SD card and all eight USB peripherals.
