Hi everybody. A few weeks ago I posted asking for a solution, because I couldn't get video out on Color 1.5 through my Multibridge Pro 2. Someone pointed out the difference between the graphic cards installed on the Mac Pro's. So, I updated mine. I had an NVIDIA 7300Gt and now I have installed a Radeon X1900XT. So, that was the problem. I finally see my color corrections on my third monitor through the Multibridge Pro 2. I hope this could be useful.
