Dual 4K docking station for USB-C hosts

This Black Box USBC2000-4KDUAL docking station connects a single USB-C laptop to two 4K displays, wired Ethernet and up to three USB 3.2 Gen 2 peripherals. It includes two USB-C host cables and delivers up to 100 W of charging per host port for a total of 200 W. The unit is suited for professionals who need a compact, high-power dock for dual-monitor workflows.

Video and data limits of the USB-C link

Dual 4K at 60 Hz over DisplayPort and HDMI requires the host to support DisplayPort 1.4; without it the dock falls back to 4K at 30 Hz. The three USB 3.2 Gen 2 ports share a 10 Gbps uplink, so simultaneous high-speed transfers will contend for that bandwidth. Gigabit Ethernet runs at 10/100/1000 Mbps and audio passes through a 3.5 mm jack.

Host must supply DisplayPort 1.4 for full refresh

If the source computer only offers DisplayPort 1.2 or earlier, the maximum refresh rate at 4K drops to 30 Hz on both video outputs. Buyers whose laptops lack DP 1.4 support should expect that limitation. The dock does not add video capability beyond what the host controller provides.

Questions about this item

Should I pick the DisplayPort or HDMI output for my 4K monitor?

Use DisplayPort when your source supports DP 1.4 for 4K at 60 Hz; HDMI also reaches 4K 60 Hz but drops to 30 Hz without DP 1.4.

Will the 10 Gbps USB ports actually hit that speed with my external SSD?

The two USB 3.2 Gen 2 Type-A and one Type-C ports are rated for 10 Gbps; real-world throughput depends on your drive and cable quality.

What does the 200 W charging figure mean for my laptop?

The dock can deliver up to 200 W total, with each USB-C host port supplying up to 100 W, so a single laptop can charge at 100 W.
