I have a Radeon 6670 2GB DDR3 card, and I am wanting to connect 3 monitors. They are generic Lenovo ThinkVision PnP monitors. There is no DisplayPort on the back of the card, but there instead is a VGA, DVI, and HDMI. For some reason, only 2 monitors can be displayed at the same time. I've went into the screen resolution in Windows 7, and it has 2 monitors working and one grayed out. (eg. 1 and 2 are normal, but 3 is small and gray) When I went into Catalyst Control Center and went into the Eyefinity tab, it didn't even show a third monitor. Just 1 and 2. Please help me get the other monitor working. Thanks in advance.
