Technical Description

The HP Thunderbolt 120W G4 Dock (4J0A2AA) is a versatile connectivity and expansion solution for modern professional computing environments. Instead of connecting individual monitors, Ethernet cables, USB peripherals and other accessories directly to a notebook, users can connect the laptop to the docking station and manage their workstation from one central connection.

At the heart of the dock is Thunderbolt 4, providing high-speed connectivity for compatible systems and peripherals. The dock also supports USB-C DisplayPort Alt Mode, allowing compatible USB-C notebooks to use display and connectivity functions according to the capabilities of the host system. HP notes that USB-C Alt Mode functionality requires the host PC to support DisplayPort Alt Mode through its USB-C port.

For display connectivity, the dock provides two DisplayPort 1.4 ports, one HDMI 2.0 port, one Thunderbolt 4 connection and one USB-C DisplayPort Alt Mode connection. Depending on the notebook's video capabilities and configuration, the platform can support up to four external displays. HP specifies support for configurations including dual 4K at 60Hz and, on suitable DP 1.4 systems with DSC, triple 4K at 60Hz.

Network connectivity is another major strength. The Ethernet interface supports both 1Gb and 2.5Gb Ethernet, giving businesses greater flexibility when connecting modern laptops to high-speed wired networks, servers, NAS devices and enterprise infrastructure.

For peripherals, the dock provides four USB Type-A ports, including powered charging ports, along with a front USB Type-C port capable of USB 3.2 Gen 2 data transfer. This makes it easy to connect keyboards, mice, external storage, printers, scanners, card readers, headsets and other USB devices.

The HP Thunderbolt 120W G4 also supports enterprise-oriented management and security capabilities such as HP Sure Start, wired vPro management, PXE Boot, Wake on LAN and MAC address pass-through on supported configurations and HP systems. These capabilities make the dock particularly relevant to corporate IT environments where centralized device management and network control matter.

The dock uses a 120W power supply and can deliver up to 100W USB-C Power Delivery to a compatible host. The supplied system includes the dock, power supply, power cord and warranty documentation.

Buying Guide

Before purchasing the HP Thunderbolt 120W G4 Dock 4J0A2AA, check these points:

1. Check Your Laptop Port

Confirm whether your laptop has Thunderbolt 3/4 or a USB-C port supporting DisplayPort Alt Mode, data and power functions. HP specifically notes that USB-C Alt Mode functionality depends on host support.

HP lists Windows, macOS and Chrome OS compatibility, while certain enterprise and Linux features may depend on the operating system and host system.

6. Confirm the Exact Product Number

Make sure the quotation or invoice specifies HP Thunderbolt 120W G4 Dock, 4J0A2AA, especially because the HP G4 family also includes other 120W and 280W variants.
