StarTech 116N-USBC-DOCK

The third screen is fundamentally different

Video groups one and two use DisplayLink and can each reach 4K60 through HDMI or DisplayPort. The third HDMI connection instead relies on the laptop’s DisplayPort Alt Mode and tops out at 4K30. Plugging into a data-only USB-C port will not supply that native third path, even if the DisplayLink screens work.

Build the desk around that asymmetry. Put the main working screens on the 60Hz connections and consider the third for a relatively static dashboard or reference window. Somebody expecting three equivalent displays should compare another architecture. The native output also remains subject to the computer’s own external-display capabilities.

A mixed laptop fleet needs a software plan

StarTech lists Windows, macOS, ChromeOS and Ubuntu support, but that is a reason to check the appropriate DisplayLink installation for each machine rather than skip compatibility review. Managed computers can introduce approval requirements that a home laptop does not have.

Charging reaches up to 100W through the included supply. The accessory selection combines 5Gbps ports with faster 10Gbps connections, plus Gigabit Ethernet and a headset jack. Save the faster sockets for devices that can use them. Before ordering for a shared workspace, record the exact host models, operating systems and intended monitor connections. That short checklist is more useful here than a blanket claim that a universal dock works identically everywhere.
