• In a multi-display configuration, 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
specifications of your connected host laptop.
• Certain monitors may be limited to 4K at 30Hz when connecting through
DisplayPort. (See
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) configuration 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 download bandwidth
allocation values. The allocation amount depends on the number and the resolution of
your connected displays.
