Run dual 2560x1600 screens at the same time? Really I say? And how would one connect the second one since 2560x1600 requires the mini DP to dual link dvi adapter, and there is only one mini DP port?
Dont always believe what Apple tells you... I called yesterday and asked about 2560x1600 support, the rep told me the mini supported it out of the box and that I would not need any extra adapter, and finished with "would you like me to place that order for you now"?
I then asked if that was really true, mentioned the dual link adapter etc, he then excused himself to talk to a "technician". When he returned he confirmed that the extra $99 adapter was indeed needed.
Use the mini dvi port for the second 2560*1600 screen.. The first 2560*1600 screen uses mini display port...
