Help with MS aspect ratio on Widescreen

Hello,

I used to play MS pre-BB on my Widescreen laptop, and I could play on full screen mode without the image distorting. Now I'm trying to play on the same laptop (just got back to maple), and things look really stretched and ugly on full screen mode.

I tried fixing the scaling options on my video card, but seems I'm missing the option to keep aspect ratio, and the other options are greyed out. Here's my video card info and a screen of the problem, what can I do?

Thanks!
