Can't get Revolution Slider to fit side nav

I cant get my slider to fit without padding on the left and right it’s looking like this
http://www.afterimageseattle.com/ and I want it to look like this: http://hb-themes.com/themes/highend/photography/ but I cant get the margin to completely disappear on both right and left. When I move the left margin to -50 it moves the margin -50 on one side it moves the container to the left but increases margin on the right… even when I put any size margin, negative or positive on the right, it makes no difference.

thanks!
