  • Quickly and easily connect the dock to your USB-C port equipped laptop (Windows only)
  • Adds dual-monitor output (dual DVI), and includes DVI to HDMI, and DVI to VGA adapters
  • A total of five USB 3.0 ports, including two front panel USB fast charge-and-sync ports (compliant with USB Battery Charging Specification 1.2)

This DVI dual-monitor docking station for laptops easily connects to your USB-C™ equipped laptop (Windows only), letting you create a full-size workstation that delivers display flexibility, fast charging, and desktop convenience to your home or office workspace.

It’s a vital laptop accessory for your USB Type-C™ equipped laptop, such as the Dell™ XPS™ 15, 13, or 12, as well as the Google Chromebook™. 

Docking through USB-C is simple

USB-C is the next generation of universal connectivity, and the connectors are small, reversible, and easy-to-use. Most new laptops feature a USB-C or Thunderbolt™ 3 USB-C port, but they often lack other vital connectivity ports.

This dock adapts to your USB-C equipped laptop to deliver a variety of useful connectivity ports, including dual-DVI video output, five USB 3.0 ports, Gigabit Ethernet, and a headset jack.

Display flexibility lets you get more done at once

Boost your productivity and add dual-monitor support to your workstation. With dual video, you can work faster by viewing more content at a glance and avoid the nuisance of rearranging or resizing multiple windows.

For extra display flexibility, we’ve included two DVI video adapters, so you can avoid the frustration and costs of purchasing additional products just to fit the displays you already use.

Now, you can leave the stress of interface limitations at the door by adapting to the most popular monitor types, right out of the box. With a range of video output options, the dock is ideal for hoteling or hot desking.

Device charging and plenty of USB 3.0 ports

Charge your mobile devices faster, with or without a laptop connected to the dock. USB charging is convenient, fast, and accessible through two always-on USB fast-charge ports on the front of the dock. You can simultaneously maintain work efficiency, while adding charge-and-sync flexibility for up to two mobile devices (two tablets, or one tablet and one smartphone).

Now, you can easily fast-charge your devices and connect numerous USB peripherals through the integrated 5-port USB 3.0 controller. Perfect for external USB 3.0 hard drives, the docking station supports UASP-enhanced performance for faster data transfer rates, which means less waiting and more productivity.

Desktop convenience and customization

With a single connection to your laptop or Ultrabook™, your required peripherals remain constantly connected. You can overcome laptop port limitations and reduce the hassle of constantly reconnecting devices (such as your wired Gigabit Ethernet connection), to create an organized and full-sized workstation with less clutter.

For greater host compatibility, you can also use the docking station with laptops that feature the more traditional USB 3.0 (USB-A) port, making it perfect for organizations that have a mix of different laptop makes and models. With the included cable and USB-C adapter, you can connect the dock to virtually any laptop, regardless of the laptop’s host USB port type.

Plus, for a clean and customized workspace you can position the docking station horizontally or vertically (tower), using the optional dock stand that’s included.

The DK30BACDD is backed by a StarTech.com 3-year warranty and free lifetime technical support.

Before You Buy

Digital Visual Interface (DVI) is a video display interface that can contain different types of signaling, based on the application. DVI cables and ports are created using different connector types to identify what application they are intended to be used in. The connector types are identified by the number of pins on the DVI connector. DVI comes in the following five different connector types: 

Single and Dual link DVI indicate the maximum resolution capabilities of the video source or video destination. The maximum resolutions are Single Link (1920 x 1080 @ 60Hz) and Dual Link (2560 x 1600 @ 60Hz).

Note: The maximum resolution of your video source and video destination are ultimately determined by the technical specifications of the devices. The connector type is not a definitive indicator of the maximum resolution.

DVI-A carries only analog (for example, VGA) with no digital component. DVI-D carries only digital video (for example, HDMI) with no analog component. DVI-I combines DVI-A and DVI-D connections to include both analog and digital components. A DVI-I port may be on either your video source or display, but whether or not a display carries either or both analog and digital sources depends on the technical specifications of your device.

No, you cannot use this docking station to charge a connected laptop computer.

To see a list of laptop docking stations that can charge a connected laptop, refer to the following FAQ: https://www.startech.com/faq/laptop-docking-stations-will-charge-laptop.

USB-C is a type of USB connector that is capable of supporting the following:

  • Data transfer speeds up to 10Gbps, if you use USB 3.1.
  • Bi-directional power delivery up to 100W, if both the USB host connection and the device support it.
  • Alternate modes, which deliver different types of data at different speeds. For example, DisplayPort Alternate Mode (DP Alt Mode).

If using Thunderbolt 3 over USB-C, the connection is capable of additional features. For example, Thunderbolt 3 is capable of 40Gbps of total bandwidth. For more information, refer to the following FAQ: https://www.startech.com/faq/thunderbolt-3-port-capabilities.

Not all USB-C ports or devices are capable of supporting all of the features listed above, or all of the features at the maximum capabilities. If you require a specific USB-C feature, your USB host connection, cables, and device must all support the feature that you require. For more information about whether your components support specific USB-C features, refer to the information provided by the manufacturers. 

This USB-C device requires that all of the following components support DisplayPort Alternate Mode:

  • The USB-C host connection (for example, a computer and its port).
  • The USB-C cable.
  • The USB-C device (for example, a hard drive docking station).

To check how much power this device requires, visit the product page, and look on the Technical Specifications tab.

For more information about the modes that your setup components support, refer to the information provided by the manufacturers.
