boxed style revolution slider

I try to get a ‘full-width’ revolution slider within the boxed wrapper style of the theme.
If i choose ‘auto’ within the settings of revolution slider then the slider is not ‘full-width’ with the boxed area (left and right some padding, see http://www.vanderborn.eu). And when i choose ‘full-width’ within the settings of revolution slider, the slider is then really full-width and ignore my boxed settings of the theme.

How can i fix this?
