Note:
Video adapters can limit the maximum available resolution. To determine the
maximum resolution your video adapter supports, consult the documentation that
came with the video adapter.
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 ports (for example, the USB 3.0 ports) depends entirely on the display and
I/O (input and output) configuration that you are using.
When you connect multiple high-resolution displays, the PCIe expansion box needs to
allocate additional bandwidth to the displays and the extra bandwidth is reallocated
from the other I/O ports on the expansion box. In this situation there is less bandwidth
available for the remaining ports (for example, the USB 3.0 ports).
