Game screen "bloats" on 32" monitor

[lars123456789]

Hi there... I just installed the game and ran the setup, I set the game to the native resolution of my screen which is 1920*1080, but the screenborders are still reaching outside the screen as if it was magnified a little.

I'm not sure if it is an issue with aspect ratios, or if it an issue with the borders in itself, the thing that'd make me think a border issue is that my taskbar is still available on the top of the screen.

It's a philips flatscreen, i'm using windows 7 ultimate, and using an nvidia gtx 285.

If anyone has an idea for a solution answes are happily accepted (unless it involves buying a new screen, i can't afford that after having bought this one here )

Found the error... it just seems i had been an idiot and forgotten to switch windows themes... computer, lack of sleep and no coffee isn't really a match
