The video cards used in the maxc will support two profiles, so if you are doing dual monitor with two hooked up, and open the display prefs, the box with the selections of profiles will appear on each screen, for that monitor. When you save the profile, you could, as a safety measure, title each profile with some sort of indicator as to which monitor it is for and when you are checking to make sure each monitor is set to ts correct profile, you will know.
