I was trying different profiles for my external monitor (make and model in signature) and I noticed there were 2 identical profiles for Adobe RGB 1998 and sRGB 2.1. Is there a reason for this? I attached a screenshot of the system preference pane that shows up on my external display when I go to Displays. Does it have to do with my external being attached? Maybe the main LCD has one of each profiles and the external display has another set?
