Apple Pro Display XDR supports iMac Pro, but only at 5K resolution

Apple Pro Display XDR monitors were launched shortly after this week’s sale, and foreign media Relay FM pointed out that iMac Pro is not included in the list of Mac models compatible with displays on Apple’s website.

However, video editor Thomas Grove Carter found that the iMac Pro can actually be used with Pro Display XDR, but only at 5K resolution. This may be because the iMac Pro uses Intel’s older “Alpine Ridge” Thunderbolt 3 controller and does not have enough bandwidth to drive a 6K display.

To use Pro Display XDR at full 6K resolution, the display must be connected to a new Mac Pro with MPX module GPU, 2018 or later 15-inch MacBook Pro, 16-inch MacBook Pro, or 2019 iMac. It is reported that all these models are equipped with Intel’s updated “Titan Ridge” Thunderbolt 3 controller.

Pro Display XDR can also work at full 6K resolution on any Mac with Thunderbolt 3 ports and Black magic eGPU or Black magic eGPU Pro. These external GPUs are also equipped with “Titan Ridge” controllers.
