HP Thunderbolt 4 Dock 120W G4 - 13-in-1 4K Multi-Display Hub

In this review the HP Thunderbolt 4 Dock 120W G4 earns its place as a serious productivity hub for professionals who need a single reliable connection for power, multiple displays and fast networking. The dock is aimed at users of Windows laptops, MacBooks and Chromebooks and the biggest reason to buy is its ability to drive up to four 4K@60Hz displays while delivering up to 100W charging and dual NIC ethernet speeds through one Thunderbolt 4 cable. It is not a casual accessory; it is designed for people who depend on consistent multi-monitor setups and high throughput for peripherals.

Key Features

• Thunderbolt 4 display support: Drives up to four 4K@60Hz displays from a single Thunderbolt 4 connection for large, crisp multi-monitor workspaces.
• High power delivery: Provides up to 100W charging to compatible laptops so users can run demanding workflows without a second power brick.
• Fast data and network: Delivers up to 40Gbps data transfer speed and dual internal NICs with 1Gb and 2.5Gb Ethernet for quicker downloads and stable wired networking.
• Plentiful ports: Includes multiple USB-A and USB-C ports, HDMI 2.0 and two DisplayPort 1.4 outputs to connect legacy and modern peripherals without extra adapters.
• Security and build: Offers a Standard Kensington lock slot for physical security and a compact footprint at 3.9 x 3.9 x 2.7 in so it fits small desk spaces.

Who It's For

This dock is best suited for professionals using HP Envy, ProBook, EliteBook, ZBook, Lenovo ThinkPad, Dell XPS or similar business and creator laptops who need multi-display setups and reliable charging. It also fits Mac and Chromebook users when the host device supports USB-C charging and DisplayPort alt mode through Thunderbolt 4 or compatible ports.

People who should look elsewhere include users with older laptops whose USB-C ports do not support charging or display output and casual users who only need one external monitor or a very small port extender. Also check your laptop9s USB-C capabilities before buying, since full Thunderbolt 4 functionality depends on the host port.
