  • 40Gbps Thunderbolt 3 certified performance for full bandwidth

CalDigit Thunderbolt 3 Mini Dock Dual HDMI

This portable docking station restores essential ports to Thunderbolt 3 laptops through a single tethered cable. It is built for users who need dual 4K display output, wired networking and a USB-A connection while travelling or working at a desk. The aluminium enclosure draws power from the host computer and does not charge it.

Professionals needing two external monitors at 4K

The dock suits Mac users on macOS 10.12 or later and Windows 10 users whose systems support two DisplayPort streams over Thunderbolt 3. Buyers whose Windows laptops only support a single DisplayPort stream will be limited to one external display. It is not for users who require laptop charging from the dock or who lack a Thunderbolt 3 port entirely.

Dual HDMI 2.0 outputs drive two 4K 60Hz displays

Each HDMI 2.0 port supports 4096 x 2160 resolution at 60 Hz for extended or mirrored desktop modes. This dual-stream capability is the deciding specification; without host support for two DisplayPort streams the second monitor will not activate. The dock also provides a USB 3.1 Gen 1 Type-A port at 5 Gb/s with 900 mA power and a Gigabit Ethernet jack.

Questions about this item

Does the dock ship with any video or USB cables, or do I need to buy HDMI leads separately?

The unit has a built-in Thunderbolt 3 tether cable for the host connection. Two HDMI 2.0 cables for the 4K@60Hz outputs and any USB-A cables for peripherals must be purchased separately.

Which ports should I use if I only have one 4K monitor versus two?

Either HDMI 2.0 port drives a single 4096 x 2160 display at 60 Hz. For dual extended monitors, plug one display into each HDMI port; both run at 4K@60Hz simultaneously.

What does the 40 Gbps Thunderbolt 3 link actually deliver for the Gigabit Ethernet and USB 3.1 Gen 1 ports?

The 40 Gbps backbone carries full 1 Gbps Ethernet throughput and 5 Gbps USB 3.1 Gen 1 data at the same time as dual 4K video, so neither port is bottlenecked by the dock.
