Universal USB 3.0 docking station

The Kensington K33991WW connects a laptop, two external monitors and multiple peripherals through a single USB-A cable. It supports dual 1080p output via HDMI, DVI or VGA using the included adapters. Compatible with Windows 7 through 10 and macOS 10.4 to 10.13. Ideal for professionals who move between meetings and a desk-based workstation.

Sustained connectivity across a full workday

The dock maintains stable video and data links during extended sessions without relying on short-burst performance. DisplayLink technology manages dual 1080p streams consistently while the two front USB 3.0 ports handle high-speed transfers at up to 5Gbps. Four rear USB 2.0 ports keep keyboards, mice and other accessories connected reliably throughout the day.

Quiet operation with minimal desk footprint

The unit runs silently with no active cooling, drawing power directly from the host USB 3.0 connection. A VESA mounting plate (sold separately) lets you attach the dock behind a monitor, removing it from the desktop entirely. Dimensions are 9.63 by 9.5 by 6.5 inches and weight is 1.65 pounds, making it unobtrusive in any workspace.

Questions about this item

Does the Kensington K33991WW run hot or make noise when driving two 1080p monitors all day?

The dock has no fan and uses a DisplayLink chip over USB 3.0, so it stays silent and only warms slightly under continuous dual-monitor load.

My laptop only has USB-A ports — will the Kensington K33991WW work without any extra adapters?

Yes, the host cable ends in a standard USB-A 3.0 plug, so any laptop with a USB-A port can connect directly.

Can I keep my older 1080p DVI monitor and add an HDMI screen at the same time on the Kensington K33991WW?

The dock provides one HDMI, one DVI-I and a DVI-to-HDMI adapter, letting you drive two 1080p displays in any HDMI/DVI/VGA combination.
