You can also connect the dock to your USB 3.0 laptop through a USB-A port, using a USB-C to A cable, such as the USB315AC1M(sold separately). Note: Power Delivery to charge your laptop is not available through USB-A, and only dual display is supported. 

Enhance Productivity 

The 4K USB-C docking station lets you create a three-monitor Ultra HD workstation. Connect: 

  • 2x 4K DisplayPort (DisplayLink) at 4096 x 2160 resolution @ 60Hz / 3840 x 2160 @ 60Hz and 
  • 1x 4K HDMI (DP Alt Mode) at 4096 x 2160 resolution @ 24Hz / 3840 x 2160 @ 30Hz 

For high-resolution applications, you can connect the dock to a 5K display at 60Hz, using the two DisplayPort ports. 

100W Power Delivery 

Using a single cable, the USB-C dock will power and charge power-hungry laptops, with up to 100W Power Delivery, and power your peripherals with its 150W power adapter.  

Powerful Connections 

This triple-monitor docking station lets you transform your laptop into a full-sized workstation. It gives you five USB 3.0 ports (1x USB Type-C and 4x USB Type-A incl. 1x Fast-Charge port), a Gigabit Ethernet port, headset jack, and separate 3.5 mm audio and microphone ports. 

Connected Device Transparency with the StarTech.com MAC Address Changer Utility

The DK30CH2DEP, includes a free Windows® application that enables you to better manage your enterprise network security. When you connect to your network through the ethernet port of the dock, the computer’s MAC address is typically not broadcast to the network, as your network only sees the MAC address of the docking station. However, the StarTech.com MAC Address Changer or Cloning software enables the USB-C dock to use MAC address spoofing of the connected Windows laptop rather than the MAC address of the dock itself. This ensures your network administrators have full visibility of each device on the network and can monitor and limit activity accordingly. To request access to our MAC Address Changer utility, please contact our Technical Support Department by phone, live chat, or e-mail.

The TAA compliant DK30CH2DEP is backed by a StarTech.com 3-year warranty and free lifetime technical support.

Frequently Asked Questions

Installation

Starting in High Sierra 10.13, macOS enforces stricter security policies than previous revisions. As a result of these changes, software packages, like those used in this installation, will need to be allowed within the macOS Security and Privacy settings, immediately after the software has been installed, in order for the device to operate.

To allow the software, follow these steps after you've completed installation on your Mac:

  1. Open System Preferences.
  2. Open Security & Privacy.
  3. Click the Allow button near the bottom of the General tab.

Note: The option to allow the software will be available within the Security & Privacy settings for 30 minutes. If the software is not allowed within that time frame, the software must be reinstalled in order for macOS to grant the opportunity to allow it again.

Note: Do not physically connect the USB laptop docking station to your computer until you are instructed to (Step 6).

  1. Download the latest drivers from the StarTech.com website (http://www.startech.com/Support). You can find the part number and product ID on the product’s packaging.

    Note: Windows will typically save the files to the Downloads folder associated with your user account (for example, C:\Users\your_name\Downloads).
     
  2. Once the download is complete, extract the files from the zip folder. Right-click the DisplayLink.zip or DisplayLinkDock.zip file, select Extract All and follow the on-screen instructions.
  3. Select the appropriate folder for your operating system.
  4. Right-click Setup.exe. 
  5. Click Run as Administrator.

    Note: If the Run as Administrator option is not available, you may be attempting to run the installer from within the zipped file. Please extract the files using the instructions in Step 2.
     
  6. Follow the on-screen prompts to install the device drivers and software. Restart the computer either when prompted, or when the installer disappears.
  7. Connect any video cables from your display(s) to the video port(s) on the docking station. 
  8. Once Windows has restarted, connect the docking station to your computer.
  9. Your computer will automatically complete the driver installation.

Note: Installation may take several seconds to complete. During the installation your display might flicker. This is normal.  Once the installation is complete you will see your Windows desktop extended to the additional monitor(s).

Note: Do not physically connect the laptop docking station to your computer until instructed to (Step 7).

  1. Download the latest drivers from the StarTech.com website (http://www.startech.com/Support). You can find the part number and product ID on the product’s packaging.

Note: Mac OS X will typically save the files to the Downloads folder that is associated with your user account (for example, hard_drive_name\Users\your_name\Downloads).

  1. Double-click the DisplayLink.zip file.
  2. Double-click the MAC OS folder.
  3. Double-click the appropriate folder for your operating system.
  4. Double-click the DisplayLink Installer 75598.dmg file.
  5. Follow the prompts to install the new drivers. Restart the computer when prompted.
  6. Once Mac OS X has restarted, connect the laptop docking station to your computer.

Note: Installation might take several seconds to complete. During the installation your display might flicker; this is normal. Once the installation has completed you will see your Macintosh desktop extended to any connected monitors.

To install the DisplayLink Manager app, please follow these steps:

  1. Download the latest driver: [displaylink] mac usb display adapter.zip
  2. Connect the StarTech.com product to both your Mac and the external display
  3. Follow Steps 4 to 4.10 here: DisplayLink Manager App for macOS [external link to DisplayLink.com]

If the displays still do not work, please review these points:

  • After installing, ensure you have completed Steps 4.4 to 4.9 in the linked article, which includes running the application after installation and selecting “Launch automatically after logging-in”.  This will ensure it starts automatically every time you log-in.
  • On Apple M1-based Macs, you may be prompted to install Rosetta during the DisplayLink install process. This is currently required to allow DisplayLink to work on Apple Silicon Macs.
  • Clamshell and rotation support on macOS Big Sur 11.x with DisplayLink Manager [external link to DisplayLink.com]

Troubleshooting

DisplayLink powered USB video adapters and docking stations are not compatible with any MacBook running macOS 10.13.4 - 10.13.6. If a system has updated to macOS 10.13.4, 10.13.5, or 10.13.6, upgrading to macOS 10.14 (Mojave) is an option for users to restore DisplayLink functionality.

At this time, the DisplayLink compatibility issue also affects any 2018 MacBook Pro laptops with an Intel Coffee Lake CPU running macOS 10.14. Please see the DisplayLink site for a driver download workaround. This workaround will force AirPlay to extend or mirror one USB display.

For alternative product recommendations including our catalog of Thunderbolt™ products, connect with our Technical Advisory team at the bottom of our Support page.

Computers running macOS Catalina (10.15) may experience compatibility issues with products that use DisplayLink technology, such as USB Docking Stations and Video Adapters. Connecting to a DisplayLink-powered Product may cause the Display(s) to output a blank screen. If you experience this problem, follow these steps:

  1. Update computer to the latest version of macOS 10.15
  2. Permit Screen Recording by following these steps: macOS Catalina 10.15: Screen Recording permission (external link)
  3. Enable the DisplayLink Kernel Extension by following these steps: macOS 10.13, 10.14 and 10.15: Video functionality not enabled (external link)
  4. If the problem persists, try installing the DisplayLink Manager Application (external link). Be sure to run the application after installation and select “Launch automatically after logging-in” for it to start automatically every time you log-in.

When you troubleshoot issues with a laptop docking station, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Video cables

  • Video source

  • Video destination

  • Laptop docking station

  • USB peripherals

  • Ethernet connection

To test your setup components, try the following:

  • Use the video cables, video source, video destination, laptop docking station, USB peripherals, and Ethernet connection in another setup to see if the problem is with the components or the setup.

  • Use a different video cable, video source, video destination, laptop docking station, USB peripherals, and Ethernet connection setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

When you test the video cables, video source, video destination, and laptop docking station it is recommended that you do the following:

  1. Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager.

  2. If you do not see the USB video adapter in Device Manager, refer to the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windows.

  3. If the device is listed with an error, reinstall the drivers following the instructions on the website.

  4. Check to see if your video card drivers are current. You can check what video card you have in Device Manager under Display adapters. It is recommended that you go directly to the video card manufacturer's website to check for the latest drivers.

  5. Check to see if the monitor is being detected by Windows.

For more information about testing the USB peripherals and the laptop docking station, visit www.startech.com/faq/usb_hubs_general_troubleshooting.

When you test Ethernet and the laptop docking station, refer to the following FAQ: http://www.startech.com/faq/network_adapters_general_troubleshooting.

When you test sound and the laptop docking station, refer to the following FAQ: http://www.startech.com/faq/sound_cards_general_troubleshooting.

Works Great with Dual [email protected] Monitors

By: STRICQ - 11/09/2020
This is the third dock I attempted to get working with my HP zBook G5. It's also the first one that works perfectly. I run 2 2K (2560x1440 at 120Hz) monitors with no issues. All USB ports work, laptop charging, Ethernet, all work. I don't move my laptop often, but when I do, I absolutely love that I only have one cable to unplug and done.

Great! But improvements are wanted!

By: BRogers - 01/17/2021
My company picked up one of these for me a while back and It's been a workhorse. Pros: 1. Plenty of ports 2. Second USB-C port 3. Quick charge port on the right side. 4. 3 functioning monitors! Cons: 1. No ports in front. Could use more than the single side-port. 2. The DP passthrough goes to the HDMI 2.0 port rather than a DisplayPort output. 3. DisplayPort ouputs are on their own controller - making them less ideal for latency and high bandwidth streams. (Gaming) 4. Sometimes it'll bug out and I'll need to reset the device and my computer. (1/month or two)
