Display Conguration
Connect HDMI, DVI and VGA Displays
Notes:
• Connect an active adapter to the DisplayPort Port.
• This port does not support Multimode DisplayPort so an active adapter is
required.
• The Docking Station lets you connect two 4K displays.
• The maximum available resolution may be limited if your display is
connected through a video adapter. Check the documentation of the video
adapter to determine its maximum supported resolution.
You can use adapters to connect HDMI, DVI, or VGA displays to the Thunderbolt
3 Peripheral Port and USB Type-C Port:
Connect Multiple Thunderbolt 3 Displays
You can also set up dual displays using multiple Thunderbolt 3 Enabled Displays
in a daisy-chain conguration. For example, you can connect a Thunderbolt
3 Enabled Display to the Thunderbolt 3 Peripheral Port on the Docking
Station. You can then connect another Thunderbolt 3 device, such as a second
Thunderbolt 3 Enabled Display, through the rst Thunderbolt 3 Enabled Display.
Note: A maximum of 2 Displays can be used with each Thunderbolt 3 Port.

12
To view manuals, videos, drivers, downloads, technical drawings, and more visit www.startech.com/support
Congure Displays
Use your Windows operating system to adjust display settings for multiple
monitors. Your laptop hardware must support dual external displays through its
Thunderbolt 3 port.
Supported Video Resolutions
The Docking Station supports the following maximum resolutions:
Number of
Displays Ports Maximum Resolution
1 DisplayPort Port 4096 x 2160p
1Thunderbolt 3
Peripheral Port 4096 x 2160p (60Hz)
2
DisplayPort Port
and Thunderbolt 3
Peripheral Port
4096 x 2160p
• Depending on the conguration and the supported resolutions of your
connected monitor(s), the Docking Station can support video resolutions
lower than specied above.
• Video output capabilities are dependent on the video card and hardware
specications of your connected host laptop.
Video Resolution and 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) conguration that
you have used.
When multiple high-resolution displays are connected, the Docking Station

13
To view manuals, videos, drivers, downloads, technical drawings, and more visit www.startech.com/support
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 download bandwidth
allocation values. The allocation amount depends on the number and the
resolution of your connected displays.
• 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 Ports, a USB-C video
adapter may be required, depending on the input of your display.
