Need help with Color 1.5 monitor setup/card
 

Hi all,
I'm running an Intensity Pro Card on my Intel Mac Pro via HDMI and each time I set my Color Correction to monitor out Nothing shows and the app locks up......I just spoke with tech support at BlackMagic Design and he said he believes that color is only SDI out.....Is this true? If so, what set up should I consider ans if I have to replace the card which is the best mid-range considering price? Thanks
