NOTE:
UHD/4K frame rates of 50, 59.94, 60 require optimum Thunderbolt 2 performance, and may
require most or all of the available PCIe bandwidth on a single Thunderbolt Port. Sharing a
single port with other devices in a daisy chain may not always be possible without risking
dropped frames on the AJA device.
