When you are in the Display Properties window, there should be 2 blue boxes representing your 2 monitors. Clicking on box 1 or 2 will select that monitor. Then when you go to the Advanced properties you can assign a profile to that monitor with the Color Managment tab.
The problem is whatever I select it always says "Current Monitor: ViewSonic VP171b-2" which has it's profile loaded, I'm trying to load a profile for my second monitor a CMV CT-722A which shows up as Plug and Play monitor.
