i hook mine up to my 40" sony 1080i
What i did is just go into the nvidia control panel for video and set it up to single display, select the tv.
i didn't use the FN/F8 feature.
it's totally obvious you don't like or enjoy your MBP, just ebay it and you'll get 1200-1300 bucks (after fee's and shipping maybe 1100+) and get a windows laptop.
