Hi all, I'm looking to upgrade to the 2013 Mac Pro later this year, and I've been eyeing the Dell UltraSharp 29 U2913WM. I'm figuring that with the FirePro's being able to pump out 4K and HDMI 1.4 being able to match that, that using this monitor with a resolution of 2560x1080 with the new Mac Pro would be a piece of cake. I've read in this and other forums that older OS's and GPU's can't run 2560x1080 through past iterations of HDMI because it's restricted to 1920x1080, but I'm assuming that with the Firepro's, Mavericks, and HDMI 1.4, it should all work. Am I right to assume this? I know this question has been answered all over the internet in the past with HDMI 1.3 or DisplayPort, but could anybody verify if my thoughts are correct or not? Thanks!
