Vista Dual Display Issues (8800GT)

Ok so I've researched for the past week and have found nothing so I figured I'd ask you guys for some help.

I just upgraded from XP to Vista Home Premium (32 Bit) and I'm having a heck of a time getting my dual display working. I'm using an nVidia 8800GT card with dual DVI out. The first is going to my 24'' HP monitor, the second is going to my 42'' LCD TV. In the nVidia Control panel, it is recognizing both however, when I go to clone the screen the secondary monitor turns on but it is just a black screen, no image.

I've been looking all over for fixes for this and have yet to find any, this is really hindering my production capabilities so any help would be much appreciated. Thank you.

Thats weird, cuz it's showing both.. hmm what driver are you running that 8800GT on. 175.19 or osmething?

I'm using the most recent driver from nVidia. (178.13)

I solved all my dual-monitor problems with a 3rd party utility, ultramonitor, which you can find at http://www.realtimesoft.com/ultramon/. I wasn't very happy with the NVidia Control Panel.
