Looking at your tv specs, it says something about a DVI interface. I'm not sure how that would work, but all recent ATI Radeon cards can always use this. And on the Recent Radeon cards with both VGA and DVI, both can be used at the same time, and can both display different things.

I'm assuming any recent NVidia card should be capable of running both DVI and VGA at the same time, and independant of each other.
