Hi All, I would like to match the dispcal -dn choice with some information on the display model/serial no etc. I want to gather this information to help in scenarios where 2 displays (same model) are present on a Mac running 10.6&up. Can anyone confirm whether dispcal -d1 will always correspond with the display marked as "Main Display: Yes" in system_profiler on mac OSX? Also I can I use ArgyllCMS to help get the Path of each Current Display Profile? Thanks in advance! Matt
