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 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 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 adapter may
be required, depending on the input.
