Did you set your aspect ratio in the menus too? If that doesn't fix it, what's your resolution set to in windows?

Right click on desktop, click screen resolution and click the "Resolution" drop down box

My resolution set in windows is 1366x768 and I haven't set any aspect ratio ?

I know, but can you change what the resolution is? Or is 1366x768 the highest it will go?

Never mind. I got a little confused here
