I'm trying to figure this out and scratching my head. Basically I am looking to purchase a new mini to replace my old dying MacPro. What I'm trying to figure out is if I can use my 2 non thunderbolt 27" ACD's with it. These ACD's have the mini display port but was wondering how I can run a dual monitor setup on the mini since it only has one MD and one HDMI. Right now on my MacPro I have one plugged in the mini display port input and use a DVI to Mini DisplayPort Converter AT-DP400 to connected to the DVI input on the second vid card. I assume I can do a similar setup in the Mini? I read somewhere though there is a limitation of 1900 x 1200 on the HDMI port? No way to get the HDMI port to push 2560x1440 to match the resolution of the ACD on plugged into the mini display/TB port???
