Compact USB-C 10Gbps Dock

The DKT31CHDVCM is a 7-in-1 USB-C multiport adapter that adds HDMI, DisplayPort, VGA, Gigabit Ethernet, two USB-A ports and one USB-C port over a single 10Gbps link. It targets mobile professionals using Windows 10, macOS, Chrome OS, Android or iPadOS devices who need legacy video and wired networking on the move. The 10-inch attached cable reduces strain on 2-in-1 ports such as iPad Pro or Surface Pro 7.

Sustained 10Gbps throughput

All three USB ports operate at USB 3.2 Gen 2 10Gbps simultaneously, so large file transfers to external SSDs maintain speed while the Gigabit Ethernet link stays saturated. The dock draws bus power for the hub itself but passes up to 75W Power Delivery through the USB-C upstream port to keep the host laptop charged during long sessions. No active cooling is present, so the aluminium chassis manages heat during continuous multi-port loads.

Single 4K 60Hz display limit

The dock drives only one external monitor at a time: 4K 60Hz via DisplayPort 1.4 or HDMI 2.0 HDR, 4K 30Hz with a DisplayPort 1.2 host, or 1080p over VGA. Buyers who need two or more concurrent external displays should choose a different solution.

Questions about this item

Does the 10Gbps USB-C 10Gbps bus power the DKT31CHDVCM dock or must I supply a 75W PD charger?

The dock runs on USB bus power alone; connect a USB-C laptop charger that supports 75W Power Delivery pass-through only if you want the host charged while the dock is in use.

Which video outputs on the DKT31CHDVCM require a DisplayPort 1.4 host to reach 4K 60Hz?

The HDMI and DisplayPort connectors deliver 4K 60Hz with a DP 1.4 host; with a DP 1.2 host they drop to 4K 30Hz, while the VGA port is limited to 1080p regardless of host version.

Will the DKT31CHDVCM Gigabit Ethernet port work on a Windows 8.1 laptop without extra drivers?

Yes, the dock is OS-independent and lists Windows 8.1 in its supported operating systems, so the Gigabit Ethernet port functions without additional driver installation.
