HP Thunderbolt Dock 280W G4 with Combo Cable - Single-Cable 4K Dock

Our review of the HP Thunderbolt Dock 280W G4 finds it best suited for professionals and hybrid workers who need a single-cable connection that can drive multiple 4K displays and power a laptop. The dock's biggest selling point is its comprehensive connectivity and robust power delivery through Thunderbolt 4, which simplifies workstation setup while supporting high-resolution displays and wired networking. For those who value stable peripheral connections and central device management, this dock provides a very practical desktop hub without excessive setup fuss.

Key Features

• Single-cable connectivity: The Thunderbolt 4 host interface delivers data, video, and power over one connection to reduce cable clutter and make docking a laptop fast and repeatable.
• 4K display support: Dual DisplayPort 1.4 and an HDMI 2.0 output enable multiple external monitors at up to 3840 x 2160 resolution for a spacious multi-monitor workspace.
• Generous USB options: Five USB ports including USB-C DP Alt Mode and several USB 3.2 Gen 1/Gen 2 ports give flexible connections for storage, peripherals, and charging.
• Wired networking: Built-in Ethernet with two internal NICs supports both 1Gb and 2.5Gb options for reliable wired connectivity and better LAN throughput than typical single-NIC docks.
• Strong power delivery: The included 280W power supply provides ample power for laptops and attached devices, noted by customers for its high-capacity performance.

Who It's For

This dock is ideal for knowledge workers, video editors, and IT-managed laptops where a single, repeatable connection is important and multiple external displays are part of the workflow. Users who need both high-speed peripheral ports and a stable wired network will appreciate the mix of USB, Thunderbolt, HDMI, and dual NIC support.

It is less suitable for minimalists who only need one external monitor or for users who want a fully wireless setup; those buyers might prefer a simpler, lower-cost USB-C hub. Also, if long-term display availability is critical in mission-critical signage, the intermittent display issues reported by some buyers are worth testing before large deployments.
