Getting background to fill entire window

Hi there,

I am having trouble getting my background graphic to fill the entire screen. The image cuts off and there is a big white space on the right when you do full screen. I made sure that the image is in a color section with the setting to fill 100% of the browser window. You can see this on the portfolio page. Do you have any recommendations? Do I need to set my image to a different dimension?
