If so do you know which profile you are using while on the 2nd monitor?

System Preferences ---> Displays
It will show ytou which color profile is being used for each monitor (a box will open on each monitor)
 
That's an answer that you can only get by looking in the Color Settings dialogue in Photoshop itself.

That's my point.. Not many knows about this and I just found out and thought I would share what I found..

Let me just say that if you are using a MBP and have a nice 2nd monitor that when you are editing photos on it, PS is using your laptops profile..I am not talking about color space, like aRGB or whatever I am talking about the calibrated monitor.
PS does not have a dual monitor setting.
You have to cheat and use the 2nd monitor profile on your laptop to view it on the 2nd monitor.. understand?
