Compact Thunderbolt 4 Hub
The ALOGIC TB4H3TB is a compact docking station built around a single Thunderbolt 4 upstream link. It targets laptop users who need to expand one port into multiple video and data connections without a bulky desktop dock. The Space Gray and Black finish suits professional environments.
Sustained Multi-Port Operation
The hub maintains its 40 Gbit/s aggregate bandwidth across three USB Type-C ports and one USB Type-A port during continuous file transfers and dual-display output. Thermal design keeps the aluminium enclosure within safe limits so throughput does not throttle during long work sessions. Power delivery stays stable for attached peripherals.
Dual 4K Display Limit
Two external monitors at 3840 x 2160 resolution are the maximum the single Thunderbolt 4 stream can drive simultaneously. A third display or higher resolution requires a separate graphics source. Buyers needing three or more screens should look elsewhere.
