Maybe Apple should've thought through its Thunderbolt layout a little bit moreīus 0, by the way, includes the bottom two Thunderbolt connectors. Since it's part of Thunderbolt Bus 0, you can't connect another 4K display on that same Bus. There are six Thunderbolt ports and an HDMI port divided between three Thunderbolt busses, and the layout isn't the most logical.Īpple says you should connect only one 4K display to each Thunderbolt bus, and when using three displays, one needs to be connected via the HDMI port. Apple's redesigned Mac Pro supports using up to three 4K displays, but it isn't quite as simple as just plugging them in and seeing the high resolution glory.
