    Current setup:

    Catalyst 12.6

    HDMI Out>HDMI In

    DisplayPort Out>HDMI In

    VGA Out>VGA In

    So, I can get each monitor to work. I can get a set of two monitors to work as long as one of them is the monitor with the active DisplayPort adapter. However, I can't get all three to work at once. When I try to extend to a third monitor, Catalyst says that one current monitor has to be disabled. How do I get my third one working??

    You have to have the same resolution on every single monitor. The VGA display resolution can be problematic.

    and if you're using three external monitors, you have to disable your laptops display and set one of the externals to primary display.
