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:
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 laptop docking station to your computer until instructed to (Step 7).
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).
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:
If the displays still do not work, please review these points:
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.

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:
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:
Laptop docking station
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:
Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager.
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.
If the device is listed with an error, reinstall the drivers following the instructions on the website.
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.
Check to see if the monitor is being detected by Windows.
