Frequently Asked Questions


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 laptop docking station to your computer until instructed to (Step 7).

  1. Download the latest drivers from the website ( 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 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
  2. Connect the 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]

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 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:

  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.

A Great Dual Monitor Docking Station

By: JHR63589 - 10/26/2017
I have been in the AV/IT Integration space for over 30 years. I found this unit easy to setup and use on my Dell, HP and Toshiba Laptops. The unit installs quickly and is compatible with a variety of operating systems, which I tested. There was no tearing of the video or audio sync issues during my testing. It was easy to set up dual displays by connecting to one HDMI and one DVI monitor. Plus, the dock includes a DVI to VGA adapter, so you can connect your VGA monitor in place of a DVI monitor. Overall, I found the unit to be reliable, easy to use and of high quality. What is Included: 1- Docking Station 1- USB 3.0 Cable 1- DVI to VGA Adapter 1- Universal Power Adapter 1- Quick Start Guide Note: “I received this product in exchange for an unbiased review.”

Most Excellent Docking (USB 3.0) Station

By: wizzard - 11/07/2017
This has become part of my essential computer tools and is used daily and I am loving it. It will work on any computer with a USB 3.0 port. It is well made. It comes with power adapters for difference countries, a USB 3.0 cable to connect to your computer, a manual, and a VGA to DVI adapter. It has Display Link drivers available for Windows and Mac (beta drivers also work in High Sierra). All work well. I have not tested any 4K display devices so can not comment on this or workability of this. This docking station provides all the essentials of USB ports (4 on back, 2 on front) as well as HDMI, DVI (via to dvi with included adapter), gig ethernet. 1 port on the front and 1 port on the back can be used to charge USB devices even when the docking station is not plugged into a computer, while the other ports are available when plugged into a USB 3.0 port. Stepping down from USB 3.0 to USB 2.0 may cause performance issues and non working of some USB devices due to speed differences. Well made and truly functional docking station and I, for one, will not part with it. This has been tested primarily on a MAC (under High Sierra) but has also been tested on Windows 10. Note: I received this product in exchange for an unbiased review.

Universal Dock with Lots of Ports

By: NickD_CA32 - 11/07/2017
I have been testing using this docking station as the primary dock for my laptop at work for the past few weeks and it has been working well. The docking station comes in a box about half the height of a shoe box. It felt heavier than I expected in the box, however once I removed it the weight was all in the AC adaptor and not the dock itself. The dock has 6 USB ports (2 on the front and 4 on the back), HDMI port and DVI port (the DVI port does both analog VGA and normal digital DVI), headphone jack and Ethernet jack. There is no microphone port and as the dock uses USB-A 3.0, it requires my laptop to be connected separately to a charger. The dock includes the DVI to VGA adaptor as well as multiple ends for the power cord to use in different countries. The power cord ends can all be inserted at 90 degrees so the AC adaptor can be plugged into the wall or power bar in different directions. When I connected the dock it for the first time it didn't seem to do anything then after 15 seconds or so I got a notice that the USB device I connected was not recognized. I went to the StarTech website to download the drivers for the dock, however before they finished downloading everything seemed to be working. The next time I re-connected the dock the warning still came up so I installed the drivers. This didn't seem to help as I kept getting the same warning. A few days later the warnings stopped coming up. I also noticed that the USB ports are extremely tight to the point I thought I was breaking something when inserting them, but they work fine once you force a USB plug in. The dock works great, nice and quick after the first day or two with it. I dislike the HDMI port as I can't find any "office" computer monitors with such a connector, but I can get an adaptor for this. I have not been able to make this dock slow down, it just work fast.

The easiest docking station you can use

By: WG Bill Ryan - 11/09/2017
I received this in exchange for an impartial review. Admittedly, I wanted it anyway so I hopped on the opportunity. I don't use monitors anymore, I have three large Smart TVS and my laptop monitor. It's an Acer VX15 which bills itself for it's high quality graphics. However to do what I need, I have two additional video cards. It has a USB C port, three USB ports, a HDMI port and a card reader. I travel non-stop and it's a nightmare, a NIGHTMARE, packing up and coming home b/c of all the hubs and all the video displays. To power things, I have extra USB video cards BTW and I run very short on usb ports. It took a minute to unpack this. I laid out my chords, powered it up and had it all set up in under 6 minutes. It was so easy that I'm sure anyone, without the instructions, could figure it out and do it well without any effort. However it's very well suited to people that travel a lot or have to take their laptops or tablets with them. Ok, so 1, 1 USB port is all it takes to power all of this. It took one port, gave me 6 USB ports, gave me another HDMI Port and runs USB 3.0. Only complaint is that it's very compact so the usb ports are a little tight, but honestly, it verges on a 'good problem'. I can't pretend I'm not overly fond of StartTech b/c of the luck I've had with their other items (In fact, I use two other StartTech products to power this setup). But it's saved me a good 10 minutes of packing time and 15 of unpacking time. And when I have to unpack, plugging in one chord instead of going through the whole ritual (and literally, it used to be a ritual to pack and unpack) is just divine. Well done. It runs a little hot sometimes, nothing much. And I didn't mention, you don't get the 'weak power' note when you are charging with it, b/c it is a charging station. Yes, it's that good.

Great USB3 Docking Station

By: Andrew11 - 11/10/2017
This docking station met and exceeded my expectations. I have 2 laptops that I use with it, and both set up and performed beautifully. There are more than enough ports for all of my devices and the unit is solidly constructed and heavy enough not to slide around my desk. I was so confident in its performance I once brought it into a conference room when a video adapter was needed, the presenter plugged in and was presenting in seconds, and also charged his phone with the fast-charge USB port! This unit “covers all the bases” with DVI port and VGA adapter, HDMI and 6 USB ports. I received this product in exchange for an unbiased review

Plug and play, works great.

By: morty - 11/15/2017
I needed a dock that would allow me to use two displays and an Ethernet port and this dock has filled that need plus more. I didn't know it before ordering but having two always on USB ports means I don't have to bring my phone charger with me any more. I just charge it off the USB ports on the dock which was actually surprisingly fast. I've used this dock on my work laptop (Windows 10) in addition to my personal Mac and both times it was as simple as plug and play. Small and lightweight, you can definitely carry this around and use it as a USB hub too. If I had one negative thing to say it would be that the LED indicator light on the front is very dull and hard to see in a lit room. Some people might like that though.
