Aspect ratio on Samsung LE40A559 stuck on 4:3

Hi Everybody

I recently bought a Samsung LE40A559 LCD TV.
Im running Windows XP SP3, with a Nvidida 6200 graphic card and my primary monitor is a Samsung Syncmaster 206BW.

First problem: I usually use clone, but since my Syncmaster cant go higher than 1680 x 1050, I cant clone and get Full HD on my LCD TV, correct?

Anyways, I tried using dualview instead, and this works, resolution on LCD TV is now 1920 x 1080. But whenever I play a movie and tries to run fullscreen on secondary display, the image is squashed and is in something like 4:3 aspect ratio. It seems know matter what I do, its still 4:3!
Im using VLC media player, and if I change the aspect ratio here, it does nothing to the video on the secondary display.

Please, is there anybody out there with a solution for this problem?
I would appreciate any help.

Thanks in advance.

Regards
Rolf

I would say get a better card for dual view support and that might support the aspect ratio of your LCD TV. Also did you also try to update your driver for your graphic card?
