Compatibility note
Full functionality (dual video + 120W charging) requires a host laptop with a Thunderbolt 4, Thunderbolt 3 or USB4 port that supports DisplayPort Alt Mode and USB Power Delivery.

Frequently Asked Questions

Does the HP Thunderbolt Dock G4 work with my laptop?
It works best with laptops that have a Thunderbolt 4, Thunderbolt 3 or USB4 port supporting DisplayPort Alt Mode and USB Power Delivery, including HP EliteBook and ZBook models. Standard USB-C data-only ports may not support full video ouTPUt or 120W charging.
How many monitors can it drive?
It supports up to two external 4K displays through its HDMI 2.0 and DisplayPort 1.4 ouTPUts, giving you a dual-screen workspace from a single cable.
Will it charge my laptop?
Yes. The dock provides up to 120W of USB Power Delivery, enough to charge and run most business and mobile-workstation laptops while keeping everything connected.
What is the difference between this and the HP USB-C Dock G5?
This Thunderbolt 4 model offers higher 40GBps bandwidth, dual 4K ouTPUt and 120W charging, whereas USB-C docks like the G5 use standard USB-C with lower bandwidth and are aimed at lighter setups.

Singular Expert Insight

Why choose the Thunderbolt Dock G4
If your laptop has Thunderbolt 4 or USB4, this dock is the cleaner, higher-performance choice over simple USB-C hubs: full 40GBps bandwidth, true dual-4K ouTPUt and 120W charging in one cable. Pair it with a couple of screens from our PC monitors range, and browse alternative docking stations if your laptop is USB-C only. For lighter, travel-focused needs a compact USB-C hub may be enough, but for a fixed desk the Thunderbolt G4 gives the most headroom.

Buyer’s Guide

Buy it if
You have a Thunderbolt 4 / USB4 laptop and want dual 4K, 2.5GBE and 120W charging from one cable.
Skip it if
Your laptop is USB-C data-only or you only need a single screen — a cheaper USB-C hub will do.
Also consider
A USB-C multi-port dock if you need broad laptop compatibility, or a triple-display dock for three monitors.
