Product purpose and audience

The HP USB-C Dock G4 is a compact docking station that connects to a notebook through a single USB-C cable. It provides charging, wired networking, and multiple peripheral ports in a device measuring 198 x 69 x 22 mm and weighing 0.355 kg. It is suited to office workers who want a one-cable desk setup with support for up to three external displays.

Who it suits and who it does not

This dock suits users whose laptops accept power and video over USB-C and who need up to three display outputs via two DisplayPort and one HDMI 2.0 connection. It also provides Gigabit Ethernet, five USB ports (including one powered USB 3.0 and one front USB-C with data and power out), and a combo audio jack. Buyers whose notebooks cannot accept charging or video over USB-C, or who require more than three display outputs, will not be able to use the dock as intended.

Deciding specification

The dock delivers up to 90 W of power through six supported profiles ranging from 5 V to 20 V, and it charges the host system while driving up to three displays simultaneously. If the host laptop demands more than 90 W or does not support USB-C power delivery and video alt mode, the dock cannot fully replace the original power supply or provide video output.

Questions about this item

Does my laptop need a USB-C port that supports video and power delivery to use the HP USB-C Dock G4?

Yes, the dock connects through a single USB-C cable that must carry video, data and charging signals to drive up to three displays and power the notebook.

Will the two DisplayPort and one HDMI 2.0 outputs work with my older monitors that only have DVI or VGA inputs?

You will need active adapters for each legacy monitor; the dock provides native DisplayPort and HDMI 2.0 signals only.

How can I confirm the dock is delivering the 90 W charge profile to my notebook after setup?

The front power button lights when the host is powered or waking, and the notebook's own battery indicator will show it is charging at the negotiated voltage.
