To use the Thunderbolt 3 ports on the top* and back of your Mac Pro to connect displays, you must have at least one Radeon Pro MPX Module installed. If a Radeon Pro MPX Module isn’t installed, the Thunderbolt 3 ports on your Mac Pro are used only for data and power.

If you use Boot Camp and install a third-party graphics card from AMD, you might need to use different AMD drivers in Windows.
