Works With Chromebook certified dock

The StarTech DK31C3MNCR is a USB-C docking station certified for Chromebooks and Thunderbolt 3/4 hosts. It provides automatic firmware updates through ChromeOS and a front screw-lock host cable for secure IT deployments. The unit includes a power button, K-Slot and Nano slot for anti-theft security, plus mounting holes for fixed installations.

Flexible multi-monitor video outputs

MST-based video supports dual 4K 60Hz monitors via HDMI 2.0b, DisplayPort 1.4 and USB-C DP Alt Mode, triple 4K 30Hz monitors or a single 5K 60Hz display when the host supplies DP 1.4 HBR3 with DSC. The jump from single-display setups is worth it when extended desktop space across two or three screens improves workflow.

Full-featured 7-port USB hub

The dock delivers two USB-A 10Gbps ports, one USB-A 10Gbps port with BC 1.2 charging, one USB-C 10Gbps port, two USB-A 480Mbps ports and a shared USB-C 10Gbps and DP Alt Mode port. It also supplies 60W Power Delivery, Gigabit Ethernet and a 3.5mm headset jack. Verify your host supports the required video bandwidth and Power Delivery profile before ordering.
