Design & Performance

Thunderbolt 4 Docking Connectivity

The HP Thunderbolt G4 Dock is designed around high-performance Thunderbolt connectivity. A single host cable connects a compatible laptop to the dock's display, USB and networking interfaces. This reduces the need to connect several accessories directly to the laptop.

Full Thunderbolt functionality requires a compatible host computer. Some USB-C DisplayPort Alt Mode systems can use supported docking features at host-dependent speeds. Check the laptop's Thunderbolt and USB-C specifications before purchasing.

Up to Four External Monitors

HP documents support for up to four external displays on compatible host systems. The dock offers two DisplayPort 1.4 outputs, one HDMI 2.0 port and a USB-C DisplayPort Alt Mode connection. These options are useful for multitasking across business applications.

Actual monitor count, resolution and refresh rate depend on the laptop's graphics hardware, Thunderbolt or USB-C bandwidth, and operating system. Four-monitor support is not guaranteed on every laptop. Check the required display configuration before ordering.

Up to 100W USB-C Laptop Charging

The HP Thunderbolt Dock 120W G4 uses a 120W external power supply. It can deliver up to 100W of USB-C Power Delivery to a compatible host laptop. This allows supported computers to receive charging power while connected to desktop peripherals.

The 120W adapter rating should not be confused with the laptop charging output. Charging power depends on the connected laptop and supported USB-C Power Delivery profile. High-power mobile workstations may need a different docking solution.

Four USB-A Ports for Accessories

The docking station includes four USB-A ports for compatible peripherals. Two side-mounted ports provide USB 3.2 Gen 2 connectivity at up to 10Gbps. Two rear USB-A ports support USB 3.2 Gen 1 speeds up to 5Gbps.

These connections are useful for keyboards, mice, external storage and other USB accessories. The side ports are convenient for frequently connected devices. Actual transfer performance depends on the peripheral and host system.

Front USB-C 10Gbps Data Port

A front USB-C 3.2 Gen 2 port supports data transfer at up to 10Gbps. HP also specifies up to 15W power output for this accessory connection. Its accessible position makes it practical for compatible USB-C peripherals.

This port is separate from the host charging connection. It is not intended to provide 100W laptop charging. Check the accessory's data and power requirements before connecting.

1Gb and 2.5Gb Wired Ethernet

The HP Thunderbolt G4 Dock provides an RJ45 Ethernet connection supporting 1Gb and 2.5Gb networking. It is useful for offices with compatible high-speed wired network infrastructure. A wired connection can also simplify access to business network resources.

Actual transfer speed depends on the network switch, Ethernet cable and connected systems. Selected HP computers support additional network management functions. These enterprise features may not be available on all non-HP laptops.

HP Sure Start Security and IT Management

HP Sure Start provides firmware integrity verification and recovery for the docking station. This helps protect the dock's firmware against certain forms of unauthorized modification. It is a valuable feature for organizations managing connected devices.

HP also documents features such as eTag asset management, PXE Boot, Wake on LAN and MAC address pass-through. Availability depends on the host system and configuration. Some management functions require supported HP business laptops.

Compact Design and Workspace Convenience

The dock measures 98 × 98 × 68 mm and weighs approximately 760 g. Its compact cube-style design takes up relatively little desk space. A Kensington standard lock slot supports physical security in shared environments.

A top-mounted power button with LED indicator is provided for supported host systems. HP specifies a 0.8-meter host cable for the 120W model. The dock is practical for office desks, hybrid working and multi-device setups.

Who It's For

The HP Thunderbolt 4 Dock 120W G4 (4J0A2AA) is suitable for business professionals, office employees, IT administrators, home-office workers, designers and users who need a connected multi-monitor workspace. It is especially useful for compatible laptop owners who regularly connect external monitors, USB storage, keyboards, mice and wired Ethernet. IT departments can benefit from HP Sure Start firmware protection and supported enterprise management functions. The dock is also relevant to selected non-HP laptops, including compatible Apple, Dell and Lenovo models, although display, charging and management features vary according to the host computer.

Simple Buying Guide

Before buying the HP Thunderbolt 4 Dock 120W G4, check whether your laptop supports Thunderbolt 4, Thunderbolt 3 or the required USB-C DisplayPort Alt Mode features. Confirm the number, resolution and refresh rate of external monitors you want to use. Review the dock's HDMI 2.0, DisplayPort 1.4, USB-C, Thunderbolt 4, USB-A and 2.5Gb Ethernet connections to ensure they meet your needs. Also verify whether up to 100W USB-C charging is sufficient for your laptop and whether the operating system supports the required docking functions.
