At work, I have a 2009 Mac Pro 2.66 Quad Xeon ... http://www.everymac.com/systems/app...-quad-core-2.66-early-2009-nehalem-specs.html ... with a 24" NEC display (1920x1080). I would like to connect a second monitor (NEC 22", 1680x1050). Am I right in thinking I just need a Mini-display-port to DVI-adapter ? I suppose I can use this for an extended desktop (not mirroring) ? Also, assuming everything's set up, can I have two different wallpapers, one for each display ?
