How many displays can be connected to Mac Pro
The number of external displays that you can use at the same time depends on the resolution and refresh rate of each display.
Using a supported hub or daisy-chaining displays can enable up to 2 displays over a single Thunderbolt port, but does not increase the maximum number of displays that you can connect. Connect the display with the highest resolution first.
Mac Pro (2023)
Mac Pro (2023) supports up to eight external displays simultaneously, based on the resolution and refresh rate of each external display.
Port groups
Mac Pro (2023) has two port groups that each support up to four displays. An 8K (7680 x 4320) at 60Hz or 4K (3840 x 2160) at 240Hz display connected over HDMI uses the bandwidth of two displays in that port group.
Port group 1: The first four Thunderbolt ports on the back and the first HDMI port on the back
Port group 2: The last two Thunderbolt ports on the back, the second HDMI port on the back, and the two Thunderbolt ports on the top of the tower enclosure or front of the rack enclosure
