My TV is connected to the DVI connection on my GeForce 6800 running the 88.61 drivers. I also have a flat panel display connected to the RGB. When Vista boots you can see both displaysbut after I log in the TV display goes black and Vista runs on the flat panel. When I go to Display Configuration it shows an analog and digital display but automatically sets it up for single display and when I try to change it to dual it won't let me. I even tried to force it to see the TV. Coincidentally, I hooked my laptop (running Vista &amp; ATI drivers) to the TV and it worked perfectly. So this tells me it's an Nvidia problem. Has anyone incountered this???
