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.

Does NOT provide power over the back USB-C port!

By: Raymond123 - 03/29/2021
My unit did not provide power on the back USB-C port so i contacted their support chat support and I was told that the USB-C port on the back does not provide laptop power unless you but the adapter listed in the description: HB30C1A1CPD. Add an extra $35 if you want to use it as a full docking station.....

Mac book Pro not able to work with the lid closed

By: lauu - 07/29/2021
It works great when you have the mac lid open, but once I close it it starts disconnecting my monitors, it's very sad because I just want to use the external monitors and don't have the space to keep my mac open, hopping to have a driver update that can solve this soon.

Barrington, Customer Support on 7/29/2021 3:38:38 PM
Drivers are developed by DisplayLink, the maker of the chip used in this docking station. Certain limitations are as result of OS constraints, and some may be resolved through a future OS or driver update. We apologize certain features aren't currently available in our dock, but please check our latest driver downloads in case this changes with a future driver release by DisplayLink.
