DVI Dual-Monitor Docking Station for Laptops - HDMI and VGA Adapters - USB 3.0

There have been issues identified between DisplayLink powered USB video adapters and docking stations with macOS 10.13.4. At this time these products are incompatible with macOS 10.13.4. DisplayLink, a third party company that manufactures chipsets, is currently working on ways to address the issue identified in the current macOS release. StarTech.com is monitoring the situation and we will update our information as it becomes available.

If a system has updated to 10.13.4, reinstalling 10.13.3 or earlier is an option for advanced users to restore DisplayLink functionality: Revert to a previous macOS version.

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: 

• DVI-A (17 pin).
• DVI-D Single Link (19 pin).
• DVI-D Dual Link (25 pin).
• DVI-I Single Link (23 pin).
• DVI-I Dual Link (29 pin).

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.

Whether this device works with the Chrome OS™ operating system or not depends on the version of the Chrome OS operating system that you’re running and the model of the Chromebook™ notebook computer that you’re using.

Existing DisplayLink® enabled USB 3.0 products natively support Chrome OS build version R55 and later, but not all Chromebook notebook computers running build version R55 and later natively support DisplayLink. Support for DisplayLink is being rolled out to Chromebook notebook computers in a series of releases. To see the build version of the Chrome OS operating system that supports DisplayLink and corresponds to the model of the Chromebook notebook that you’re using, view the following knowledge base article on the DisplayLink website: http://support.displaylink.com/knowledgebase/articles/891030.

You can use an external display or projector with a Mac notebook while its built-in display is closed. This is known as "clamshell" or "closed display" mode.

Clamshell mode requires that the following devices are connected to the Mac notebook: 

• A power adapter.
• An external keyboard, mouse, or trackpad.
• An external display.

macOS does not see DisplayLink displays as external displays, therefore this criteria is not met and clamshell mode cannot be enabled when a DisplayLink adapter is the only external display connected to the computer.

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.
