Hi. I've been looking everywhere and i can't see to find it but what I'm trying to do here is watch movies or ect with one screen and play games with the other. i have the thunderbolt port going to a 30" screen and the hdmi going to a tv. I can't seem to get it to work. all i can do is set the 30" as the main display and play games while the other just sits there. basically all i want to do is use xbmc on one screen and play games on the other. thanks.
