Multi-Stream Transport for Driverless Displays

The multi-stream transport technology (MST) in this dock powers two HDMI monitors with no driver installation required so you are up and running faster.

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

The DK30C2HAGPD, 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.

Frequently Asked Questions

Troubleshooting

By default, most systems will duplicate to multiple displays when a MST hub is attached. If you are getting mirrored displays and cannot detect more than one display in Screen Resolution or Display Settings, your graphics card may not be compatible with MST. For more information about how to determine if your graphics card is MST compatible, refer to the following FAQ: https://www.startech.com/faq/mst-hubs-gpu-compatibility

If you are using a version of Mac OSX, refer to the following FAQ for more information: https://www.startech.com/faq/mst-hubs-mac-osx-support.

Sometimes an on-board network interface card (NIC) conflicts with a new NIC.  In these cases it is best to disable the on-board NIC.

The best way to disable your on-board NIC is to go into your BIOS and disable it there if possible.  To do this, consult your motherboard manual.

You can also disable any NIC in Windows.  Here is how you do this:

First click Start, or, in Windows 10 and 8, hold down the Windows key and press X.  Then click Control Panel.

Windows 10

  1. Click Network and Internet.
  2. Click Network and Sharing Center.
  3. On the left, click Change adapter settings.
  4. Right-click the NIC that you would like to disable and select Disable.

Windows 8

  1. Click Network and Sharing Center.
  2. On the left, click Change adapter settings.
  3. Right-click the NIC that you would like to disable and select Disable.

Windows 7

  1. Click Network and Internet.
  2. Click Network and Sharing Center.
  3. On the left, click Change adapter settings.
  4. Right-click the NIC that you would like to disable and select Disable.

Windows Vista

  1. Click Network and Sharing Center.
  2. On the left, click Manage network connections.
  3. Right-click the NIC that you would like to disable and select Disable.

Windows XP

  1. Click Network Connections.
  2. Right-click the NIC that you would like to disable and select Disable.

If you are experiencing flickering issues with the MST hub, your monitors may be at a 59 Hz refresh rate. If they are at 59 Hz, you need to adjust the refresh rate to 60 Hz. In order to change your monitor's refresh rate, complete the following:

  1. Right-click anywhere on your desktop.
  2. Click Screen resolution or Display settings.
  3. At the top of the screen, select the monitor that you want to change the refresh rate for.
  4. Click Advanced settings or Display adapter properties.
  5. On the Monitor tab, click the Screen refresh rate drop-down list.

Note: This step may vary depending on your operating system and graphics card.

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.

Installation

Prior to installing this device, ensure that your operating system is up to date (for example, you have installed the most recent service pack).

To install the driver:

  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 that is associated with your user account (for example, C:\Users\your_name\Downloads).

  1. Once the download is complete, right-click the zip folder that you downloaded, select Extract All, and follow the on-screen instructions.
  2. Select the appropriate folder for your operating system.
  3. Right-click Setup.exe. 
  4. Click Run as Administrator.

Note: If the Run as Administrator option is not available, you might be attempting to run the installer from within the zipped file. Extract the files using the instructions in Step 2.

  1. Follow the on-screen prompts to install the device drivers and restart the computer when prompted.
  2. Your computer will automatically complete the driver installation and your device should be ready to use.

Before You Buy

Yes, you can use this laptop docking station to charge a laptop computer. 

For more information on what the requirements are and about how much power this laptop docking station provides, refer to the product manual.

This USB-C device requires that all of the following components support alternate modes:

  • 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)

If your host device includes a Thunderbolt™ 3 connection, this USB-C device will work with your host device.

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

Recent versions of DisplayPort include the ability to split to multiple displays from one DisplayPort connection using Multi-Stream Transport (MST).

Although you will be able to connect the MST hub to the Mini DisplayPort (mDP) connection on your Mac, Mac OSX does not support MST for NVIDIA and Intel Graphics Processor Units (GPUs). This results in a mirrored image across the outputs of a MST hub and you will not be able to have multiple independent displays on your Mac.

The limitation of NVIDIA and Intel GPUs lies within Mac OSX. If a different operating system is used, such as Microsoft Windows via Bootcamp, you may be able to use the MST functionality of your Mac.

Excellent Dual-Monitor USB-C Mulitport Adapter

By: jrh865379 - 01/07/2019
I have been in the AV/IT Integration space for over 30 years. I found this unit easy to setup and use on my Microsoft, Android and Apple devices. This unit has the ability to simultaneously fast-charge your peripheral devices. The unit installs quickly with no additional drivers or software required, and is compatible with a variety of operating systems, which I tested. By using the DP Alt Mode switch, I found that you can choose between higher display resolution or faster USB speed to meet your specific needs, for both desktop and/or portable use. this unit is a must for the home office or road warrior. What is Included: 1 - Multiport Adapter 1 - USB-C Cable 1 - Quick Start Guide Note: “I received this product in exchange for an unbiased review.”

Excellent adapter for the office or on the go

By: ShawnO21 - 01/22/2019
This adapter worked well on all devices with which I tested. The passthrough power is great and a necessity on any dock or adapter in today's technical environment. An excellent option for those with USB-C and the need for additional displays. The installation is as easy as physically connecting the device and connecting HDMI displays, no software installation necessary. I received this product in exchange for an unbiased review.

Made to travel

By: Andrew11 - 01/30/2019
This is a great adapter for those who travel or present on the road, or want a minimalist setup on a desk. For the latter; the adapter has dual HDMI, Gigabit Ethernet and USB, plus USB-C charging through your USB-C charging adapter. The cable to connect it isn’t built into the box, rather is separate and 3 feet long, and provides options for very clean desktop setups. For the former; for all its many compact features, my only comment would be that there is no mechanism for transporting it. I would have loved to see a pouch or case to put it (and its cable) inside and take it on the road. It’s a very attractive unit, metal case for heat dissipation, and a genius switch for choosing one or 2 monitor outputs or USB2 or 3 speeds depending on your needs.
