Dubbelskärms-, KVM-, USB 3.0-dockningsstation för två bärbara datorer

Problem har identifierats mellan DisplayLink-drivna USB-videoadaptrar och dockningsstationer och MacOS 10.13.4. För närvarande är dessa produkter oförenliga med MacOS 10.13.4. DisplayLink, ett tredjepartsföretag som tillverkar chipset, arbetar på att lösa problemet som identifierades i den senaste versionen. StarTech.com övervakar situationen och uppdaterar vår information när den blir tillgänglig.

Om ett system har uppdaterats till 10.13.4, är 10.13.3, eller tidigare version, ett alternativ för avancerade användare att återställa DisplayLink-funktionaliteten: Återgå till en tidigare version av MacOS.

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.

No, you cannot use this docking station to charge a connected laptop computer.

To see a list of laptop docking stations that can charge a connected laptop, refer to the following FAQ: https://www.startech.com/faq/laptop-docking-stations-will-charge-laptop.

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).

2. Double-click the DisplayLink.zip file.
3. Double-click the MAC OS folder.
4. Double-click the appropriate folder for your operating system.
5. Double-click the DisplayLink Installer 75598.dmg file.
6. Follow the prompts to install the new drivers. Restart the computer when prompted.
7. 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.

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.
