Connect a display to Mac Pro
The Thunderbolt 4 ports 
and the HDMI port on Mac Pro support video output, so you can connect external displays, projectors, or HDTVs to these ports.
Before you begin
Check the documentation that came with your display to see which port you should use: HDMI, Thunderbolt, or either one. Also, make sure you have the correct cable to connect your display.
When you connect a display, you can select a resolution and refresh rate (Hz) for that display. If you increase the refresh rate for your display, you should select a lower resolution for best performance. Use Displays settings in System Settings to adjust the refresh rate and resolution of your display. For more information, see Change your Mac display’s resolution in the macOS User Guide.
If you’re not sure how many external displays your Mac Pro supports, check your Technical Specifications. Open System Settings, then choose Help > Mac Pro Specifications.
Connect displays to Mac Pro
Make sure your Mac Pro and display are both connected to power, then connect your devices using the proper cable and ports. See the Apple Support article If your external display is dark or low resolution.
You can connect up to eight external displays to your Mac Pro in many different configurations, such as:
Connect two external displays with up to 8K resolution at 60 Hz using the HDMI ports.
Connect two external displays with up to 4K resolution at 240 Hz using the HDMI ports.
Connect three external displays with up to 6K resolution at 60 Hz using the Thunderbolt ports.
Connect three external displays with up to 4K resolution at 120 Hz or 144 Hz using the Thunderbolt ports.
Connect eight external displays with up to 4K resolution at 60 Hz using the Thunderbolt ports.
Tip: When connecting multiple displays, connect the display with the highest resolution first.
For more information about the display configurations for your Mac Pro, see Apple Support article How many displays can you connect to Mac Pro.
To learn more about using an 8K display with your Mac Pro, see the Apple Support article Use an 8K display with your Mac.
What cable do I need?
If your display has a connector that doesn’t match the port you want to use, you may be able to use it with an adapter (sold separately). Visit apple.com, your local Apple Store, or other resellers for more information and availability. Review the display’s documentation or check with the display’s manufacturer to make sure you choose the right adapter. See the Apple Support article Adapters for the Thunderbolt 4, Thunderbolt 3, or USB-C port on your Mac.
