Currently I have a 2011 MBP for personal use and my work computer is a 08 MBP Uni with mini display port. I know my 08 is useless with the ATD, which really sucks. I want more screen real-estate at home, for work and personal use. Work provided me with a ****** Lenovo 20 monitor that I cannot get to calibrate to match either of my macs, and the color difference is agonizing. Will I have the same profile issues with the Dell that I am having now? Are there any hardware adapters out there that would allow a mini display port to run on a thunder bolt monitor? Or should I just find a old ACD 27 and hope it works in my 2011 MBP.
