I have a HP7700 desktop PC running Windows 7 Enterprise with a video card that has both a VGA _AND_ a DVI output. I connected two monitors to it, one to the VGA and the other to the DVI output. However, when I tried to configure them as an extended desktop, I see next to the Display just the one option, "(Default Monitor) on" with a drop-down window. When I click on the drop-down window, I see the same identical option. Normally, I should see two options, the second one allowing me to choose multiple monitors. So, basically, I am stuck with the same display on both monitors.
Thanks in advance.
