your connected host laptop.
You can connect a dierent type of display, such as a DisplayPort or VGA monitor using
an active video adapter (sold separately):

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 docking station functions depends entirely on the
display conguration you used.
Manual Revision: March 31, 2020 9:44 AM
The Docking Station supports the follow maximum resolutions:
Number of
Displays
Ports Maximum Resolution
1 1 x HDMI ports 4096 x 2160p (60Hz)
2 2 x HDMI ports 4096 x 2160p (60Hz)
Notes: 3840 x 2160p resolution, found on most standard 4K Displays, 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 Display
Devices to the same values, otherwise your monitors might not properly 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 3 compliant
1. Make sure that you are using Thunderbolt compliant cables. Thunderbolt 3 uses
the same connector type as USB-C. If you are using a USB-C cable that is not
Thunderbolt compliant, replace the cable with one that is compliant.
2. 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.
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.
