Connect displays to the Thunderbolt 3 ports on your Mac Pro

You can connect displays to the HDMI and Thunderbolt 3 ports on your Mac Pro and Radeon Pro MPX Module. If your display uses DisplayPort or HDMI, you can use a Thunderbolt 3 adapter to connect your display to the Thunderbolt 3 ports on your Mac Pro.

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 can be used only for data and power.

Starting up your Mac Pro

When you start up your Mac Pro, one connected display initially illuminates. Any additional displays illuminate after your Mac is finished starting up. If one or more displays don't illuminate after startup completes, make sure your displays and any display adapters are connected properly.

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