So maybe not the run of the mill requirement for the new Mac Pro, but was hoping that with Mavericks and the nMP that you'd be able to run Keynote across multiple displays. For instance, make presentation 3840 x 1080 to go across 2 displays "natively" on the nMP's multiple display port outputs. And 5760 x 1080 across three etc, yes I know that Keynotes max resolution is 4000 pixels wide. But no. Yes you can utilise the Matrox Double/Triple Head or Datapath X4's but was hoping for natively this could be achieved with the D700's power!? And I've also noticed that even running a Quicktime movie and move it across two displays and it will only play a portion on one display!? Maybe I got the wrong idea of Apple going "multi-monitor" orientated with Mavericks and the nMP? Anybody heard of a workaround?
