Multiple Monitors using LCD TV

I have a Samsung LCD 720P HDTV 32" that I have been using as a secondary
monitor. I just bought a new computer (HP Elite M9060N) with vista on it and
a Geforce 8500GTS NVIDIA card (factory installed). When I try to extend my
desktop onto my tv (using Dualview) it doesn't fill the entire screen. It
leaves a black ring around the outside. I've tried adjusting the resolution,
but it doesn't work. In addition to the ring, the resolution on the tv looks
horrible. I have the refresh rate maxed out and tried flip flopping which
monitor is my primary but just can't seem to get it to work. I'm also using
a Samsung LCD 20" monitor. I would appreciate any help...thanks

Oh...and I am connected using an HDMI cable.
