Pro Display XDR Limited to 5K With iMac Pro

Joe Rossignol:

Thomas Grove Carter has since demonstrated that the iMac Pro can in fact drive the Pro Display XDR, but only at a 5K resolution. This is likely because the iMac Pro uses Intel’s older “Alpine Ridge” Thunderbolt 3 controller without enough bandwidth to drive a 6K display.


To use the Pro Display XDR at its full 6K resolution, the display must be connected to the new Mac Pro with MPX Module GPUs, a 2018 or later 15-inch MacBook Pro, a 16-inch MacBook Pro, or a 2019 iMac.

This makes sense given that the iMac Pro’s specs haven’t been updated since it was announced in June 2017. Hopefully that will change soon.
