Cable Matters 201343 20Gbps USB-C Switch for 3 Computers (140W PD / 8K@30Hz or 4K@144Hz / $79.99) Review
Cable Matters 201343 20Gbps USB-C switch shares one USB-C or Thunderbolt 4 monitor or dock between 3 computers, with up to 8K@30Hz / 4K@144Hz video and 140W Power Delivery passthrough.
The 3-input version of Cable Matters' USB-C dock switch, for desks where a third machine - a test rig, a personal laptop, a loaner - needs occasional access to the same monitor and dock as your two main computers.
Overview
Functionally identical to the 2-port 201352 but adds a third USB-C host input, so three computers can take turns driving a single USB-C/Thunderbolt monitor or dock at up to 8K@30Hz with full 140W charging passthrough.
