CalDigit shipped two new bus-powered mini Docks that can be used to drive two 4K displays at 60Hz via a single Thunderbolt 3 connection.

The new Mini Docks are available with either two HDMI 2.0 or two DisplayPort 1.2 connections along with USB 3.0 and Ethernet jacks. Because they’re bus-powered, no additional power cable is required, meaning the add minimal clutter to a desktop.

CalDigit said both versions of the new Mini Docks work on both Mac and PC platforms, but warned that some Windows systems cannot support dual monitors on a single Thunderbolt 3 port.  The HDMI Mini Dock supports both UHD (3840 x 2160) and 4K (4096 x 2160) video.

The Thunderbolt 3 Mini Dock lists for $130 with DisplayPort connections or $140 with HDMI connections.
