Q: Intensity Shuttle for Color

I have recently purchased a Blackmagic Intensity Shuttle and Asus PA 238. Anyone out there have any advice as to the best settings to use for grading in Color. Another probelem is that I can use the PA238 as a second monitor with FCP 7 but not with Color. (Also unable to detect the Monitor through system settings so must be the settings I am using with the Shuttle)

Any help would be hugely appreciated thank you.
