hi guys. ive got a late 2013 mac pro (trash can) and just bought myself a Dell UP3214Q 4K monitor. i would like to run the monitor at 60hz and was wondering which cable to use. I did some googling and could not find a definitive answer to my question. But from my research it says to get 'Displayport 1.2 to mini Displayport' cable. is this right? can i get a 'mini Displayport to a mini Displayport' cable? will that be sufficient to run the monitor at 60hz? any help is appreciated! thanks!
