Hey guys, I've calibrated my 15" uMBP screen with the Spyder2Pro and am very happy with the results. However, I'll soon be hooking up my MBP to my 22" Dell 2209WA (IPS) monitor and would like to know if I need to "re-calibrate" it. How can I differentiate between the calibration of my 22" monitor and that of my MBP screen. Should I just create two color profiles? One for use when the MBP is connected to an external monitor and another for when I'm using the MBP as a stand-alone? What are your thoughts and is there a better (more intuitive) version of doing this? Thanks!
