how to get wide screen monitor working

[WIdgeteye]

I have version 3.2.10 r66896 and got windows 7 working but the only thing I have run into is I can't get the wide screen monitor to go wide screen. I tried seamless but it is greyed out. It works fine under linux host.

I downloaded the nvidia drivers for this card (nvidia GeForce 6150) but when I try to install it says it can't detect the card.
can someone tell me what I need to do?

Thanks
