HP Thunderbolt Dock 280W G4 - Combo Cable Docking Station

The HP Thunderbolt Dock 280W G4 is a single-cable docking solution built on the Thunderbolt 4 standard, which specifies a guaranteed 40Gbps bidirectional bus — double the minimum bandwidth of USB4. In practice, that bandwidth allocation means you can drive two DisplayPort 1.4 displays and one HDMI 2.0 display simultaneously at 4K@60Hz each, while maintaining 2.5Gb wired Ethernet throughput and USB 3.x peripheral speeds, all without the bus becoming a bottleneck. The 280W power supply is the headline number here: it's large enough to run the dock, charge a workstation-class notebook at its full PD rate (up to ~140W negotiated), and still leave headroom for USB-powered peripherals — something that 100W or 130W Thunderbolt docks simply can't do for high-draw systems under sustained CPU and GPU load.

This dock is engineered for professionals whose laptops are the center of a stationary multi-display workstation — engineers, video editors, or power users who want a single-cable dock/undock workflow without sacrificing peripheral bandwidth. The included vPro management compatibility (Windows) adds value in enterprise IT environments where remote management of docked endpoints is a requirement. For creative workflows, the triple-display capability combined with USB-C DP Alt Mode on one of the downstream ports expands the peripheral connection topology. At 3.9 inches square, the G4 has a compact vertical footprint that suits under-desk placement, though the fixed combo cable means stand placement relative to the laptop matters more than with user-swappable cable designs.
