Active adapters are required if adapting DisplayPort to HDMI or DVI monitors. Active adapters use additional chips to make the conversion inside the adapter. Passive DisplayPort to HDMI or DVI will not work with this device.
Prior to installing this device, ensure that your operating system is up to date (for example, you have installed the most recent service pack).
To install the driver:
Note: Windows will typically save the files to the Downloads folder that is associated with your user account (for example, C:\Users\your_name\Downloads).
Note: If the Run as Administrator option is not available, you might be attempting to run the installer from within the zipped file. Extract the files using the instructions in Step 2.
Sometimes an on-board network interface card (NIC) conflicts with a new NIC. In these cases it is best to disable the on-board NIC.
The best way to disable your on-board NIC is to go into your BIOS and disable it there if possible. To do this, consult your motherboard manual.
You can also disable any NIC in Windows. Here is how you do this:
First click Start, or, in Windows 10 and 8, hold down the Windows key and press X. Then click Control Panel.
If you are experiencing flickering issues with the MST hub, your monitors may be at a 59 Hz refresh rate. If they are at 59 Hz, you need to adjust the refresh rate to 60 Hz. In order to change your monitor's refresh rate, complete the following:
Note: This step may vary depending on your operating system and graphics card.
By default, most systems will duplicate to multiple displays when a MST hub is attached. If you are getting mirrored displays and cannot detect more than one display in Screen Resolution or Display Settings, your graphics card may not be compatible with MST. For more information about how to determine if your graphics card is MST compatible, refer to the following FAQ: https://www.startech.com/faq/mst-hubs-gpu-compatibility.
If you are using a version of Mac OSX, refer to the following FAQ for more information: https://www.startech.com/faq/mst-hubs-mac-osx-support.
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.

To arrange extended displays on Windows 10, complete the following.
To arrange extended displays on macOS, complete the following.
Recent versions of DisplayPort include the ability to split to multiple displays from one DisplayPort connection using Multi-Stream Transport (MST).
Although you will be able to connect the MST hub to the Mini DisplayPort (mDP) connection on your Mac, Mac OSX does not support MST for NVIDIA and Intel Graphics Processor Units (GPUs). This results in a mirrored image across the outputs of a MST hub and you will not be able to have multiple independent displays on your Mac.
The limitation of NVIDIA and Intel GPUs lies within Mac OSX. If a different operating system is used, such as Microsoft Windows via Bootcamp, you may be able to use the MST functionality of your Mac.
Yes, you can use this laptop docking station to charge a laptop computer.
For more information on what the requirements are and about how much power this laptop docking station provides, refer to the product manual.
This USB-C device requires that all of the following components support alternate modes:
If your host device includes a Thunderbolt™ 3 connection, this USB-C device will work with your host device.
For more information about the modes that your setup components support, refer to the information provided by the manufacturers.
