HP's enterprise Thunderbolt 4 dock connects to a host laptop over a captive combo cable that pairs Thunderbolt 4 with DisplayPort, allowing two simultaneous video streams up the link. Around the back, two DisplayPort 1.4 outputs sit alongside HDMI 2.0 and a USB-C Alt Mode port that can also carry video — so up to four 4K displays attach without daisy-chaining. The dock pushes up to 100W to the host (or 230W on the higher-power 280W PSU variant) and carries dual NIC silicon for both 1Gb and 2.5Gb Ethernet. Front-panel I/O adds a 15W USB-C 10Gbps charging port for phones and accessories.
HP’s enterprise TB4 dock with combo cable host link, 4-display support (2x DP 1.4, HDMI 2.0, USB-C Alt), 2.5GbE and 100/230W PD.
