I have a 2013 Mac Pro running OS X 10.10.5 with 3 monitors: a 4K, 2560 X 1600, and 1920 X 1080. All are connected to thunderbolt ports. No matter which ports I use all three monitors always appear to be connected to the D700 GPU in slot 2 and never to the one in slot 1. Is this normal or unusual?
Got a tip for us?
