automatically install some of the required drivers once
connected to your Host Computer. Follow the below
instructions to complete the full driver installation process.
1. Using a Web browser navigate to www.startech.com/
TB3DKDPMAW.
2. Click the Support tab.
3. Download the drivers.
4. When the download is complete, extract the contents of the

5. Double-click the appropriate driver for the version of
Windows that you are running and follow the on-screen
instructions to complete the installation.
Note: If you are prompted to restart your computer, do so to
complete the installation.
Charging a Device
If using the front USB-A port to charge a device, a connection to
a Host Computer isn’t required.
• Connect a USB device to the USB-A port located on the front
of the docking station.
Notes: This front USB-A port can only fast-charge connected

devices that comply with USB Battery Charging Specication
Revision 1.2.
When the docking station is connected to a Host Computer,
the front USB-A port functions as a Charging Downstream
Port (CDP), which has simultaneous charge and sync capabilities.
Conguring a Display Device
Use your Windows operating system to adjust display settings
for multiple monitors. Your laptop hardware must support dual
external displays.
• You can set up dual displays by using the video output ports
(1x DisplayPort and 1x HDMI).

Connect a display to the DisplayPort port
The docking station’s DisplayPort connection supports
DisplayPort 1.2, as well as DP++. Because the port supports
DP++, you can use passive adapters or cables to connect
dierent types of monitors to the DisplayPort port.
Type of Display Adapter
DisplayPort None
HDMI DisplayPort to HDMI 4K Audio/Video
Converter (DP2HD4KS)
DVI DisplayPort to DVI Adapter (DP2DVI2)
VGA DisplayPort to VGA Adapter (DP2VGA2)
Connect a display to the Thunderbolt 3 USB-C port
You can also connect a display (or a display adapter) to one of
the docking station’s Thunderbolt 3 ports. One of the docking
station’s Thunderbolt 3 ports must remain connected to your
Host Computer.
Type of Display Adapter
DisplayPort None
HDMI USB-C to DisplayPort Adapter Cable

VGA USB-C to VGA Adapter (CDP2VGA)
Visit www.StarTech.com/AV/usb-c-video-adapters/ for a range
of USB-C video adapters and cables.
Notes:
• The docking station lets you connect two 4K displays.
• The maximum available resolution might be limited if
your monitor is connected through a video adapter. Check
the documentation of the video adapter to determine its
maximum supported resolution.
Connect multiple Thunderbolt 3 displays in a daisy chain
You can also set up dual displays using multiple Thunderbolt
3 displays in a daisy-chain conguration. For example, you can
connect a Thunderbolt 3 display to the Thunderbolt 3 port on
the docking station. You can then connect another Thunderbolt
3 device, such as a second Thunderbolt 3 display, through the
rst Thunderbolt 3 display.

Supported Video Resolutions
Thunderbolt technology supports both video and data
throughput. However, it prioritizes video bandwidth to help
ensure seamless display performance. The performance of
the remaining dock functions depends entirely on the display
conguration you used.
The docking station supports the follow maximum resolutions:

• 3840 x 2160p resolution, found on most standard 4K
monitors, is also a fully supported resolution
• Depending on the conguration and the supported
resolutions of your connected monitor(s), the docking station
can support video resolutions lower than specied above.
• In a multi-display conguration, set the refresh rates on each
of your connected monitors to the same values, otherwise
your monitors might not properly display.
• Video output capabilities are dependent on the video
card and hardware specications of your connected Host
Computer.
• Certain monitors may be limited to 4K at 30Hz when
connecting through DisplayPort. (See Troubleshooting for
further details).
Bandwidth Allocation
Thunderbolt technology carries video and data bandwidth, and
it prioritizes video bandwidth to help ensure seamless display
performance. The performance of the remaining dock ports (for
example, the USB 3.0 ports) depends entirely on the display and
I/O (input and output) conguration that you have used.
When multiple high-resolution displays are connected, the
docking station needs to allocate additional bandwidth to the
displays, and the extra bandwidth is reallocated from the other
I/O ports on the docking station. In this situation there is less
bandwidth available for the remaining ports (for example, the
USB 3.0 ports).
The bandwidth allocation table outlines the approximate

• The bandwidth values are approximate and depend on
several variables including the number, type, resolution, and
refresh rate of your connected display(s).
• When connecting a display to one of the Thunderbolt
3 USB-C ports, a USB-C video adapter may be required,
depending on the input of your display.
Troubleshooting
If you are experiencing issues, there are some quick tests that
you can complete to narrow down the source of the issue.
Update your computer to use Thunderbolt 3
Visit http://thunderbolttechnology.net/updates and look
for your computer in the list of aected computers. If your
computer is listed, then you must update your computer for
its Thunderbolt 3 ports to function properly. To update your
computer, follow the instructions on the website or contact
your manufacturer.
Verify that your components are Thunderbolt compliant
6. Make sure that you are using Thunderbolt 3 certied cables.
7. Make sure that the port on your computer is Thunderbolt
3 compliant. Thunderbolt 3 uses the USB-C connector
type, but not all USB-C connectors are compatible with
Thunderbolt 3. If you are using a USB-C port that is
not Thunderbolt 3 compliant, switch to a port that is
Thunderbolt 3 compliant.
8. Make sure that your peripheral is Thunderbolt compliant. If
you’re not sure, check with the manufacturer.
To view manuals, videos, drivers, downloads, technical drawings, and more visit www.startech.com/support
16
Replace the Thunderbolt cable
• Use the Thunderbolt peripheral with a dierent cable that is
Thunderbolt compliant.
Test the Thunderbolt peripheral
1. Use a second Thunderbolt peripheral, and see if it works.
Ideally, the second peripheral is one that you know works
in other setups. If the second peripheral works in the
current setup, then there is probably an issue with the rst
Thunderbolt peripheral.
2. Use the Thunderbolt peripheral with a second setup. If it
works in the second setup, then there is probably an issue
with the rst setup.
Important operation notes
• Certain monitors may be limited to 4K at 30Hz when
connecting through DisplayPort. These monitors include
the following models: Dell P2715Q, Viewsonic VX2475Smhl4K, Philips 288P6LJEB, LG 31MU97C-B, Asus PB287Q (these
models will need to be set to 4K at 30Hz).
