Full-width slider soliloquy lite

Having trouble getting the slider to cover the full width of the page. Using Headway base theme. Images are 1583 X 680 and will not cover full width of page even when browser width is scaled down to less than image width.

Searched other posts; the only ones that I found simply admonished the OP to open a support ticket because they are on the paid version.
