Hey guys, I just bought a second monitor for my mac pro and I am having trouble getting it set up the way I want in windows. For some reason windows only uses my second monitor as the main display. Under the display properties/settings tab the (use this device as primary monitor) is grayed out on both displays. Also, if I click advanced I do not get any of the ATI options you would normally see when having a graphics card installed, only the basics. Any ideas on how I can get this to work, and can I get it to support rotation/portrait? Thanks again!
