Twice 1920x1200, once 2560x1440. All monitors have both DisplayPort and HDMI. (1) Any way that it'll work on 2011 Mac Mini (via daisy-chaining or something else ... but not with $200 "adapters")? (2) Is the discrete GPU needed? (3) What about the 2009 models (with DVI and mini-DisplayPort)? Thank you.
