1 Studio Display and 2 Thunderbolt Displays on Mac Pro 2019

Hello, I have a Mac Pro 2019 with an AMD Radeon Pro 580X 8 GB graphics card. So far, I have connected three Thunderbold displays with the Thunderbold 2 to Thunderbold 3 adapters. Without any problems. I now wanted to swap a Thunderbolt Display for a Studio Display. But now only the Studio Display and one of the Thunderbold Displays are recognized.

Mac Pro, macOS 15.2

your Mac and its display card specs are here:


Mac Pro (2019) - Technical Specifications - Apple Support


  • AMD Radeon Pro 580X
    • 36 compute units, 2304 stream processors
    • 8GB of GDDR5 memory
    • Up to 5.6 teraflops single precision
    • Two HDMI 2.0 ports on card
    • Four DisplayPort connections routed to system to support internal Thunderbolt 3 ports
    • Support for up to six 4K displays, two 5K displays, or two Pro Display XDRs
    • Half-height MPX Module fits in an MPX bay and enables PCIe slot 2 for additional expansion


trouble with Thunderbolt connections suggest you may be seeing an issue with too many data streams too close together. Try distributing your displays over more divergent Thunderbolt ports, including the TOP ports if not already in use.
