Twenty Fourteen Slider too small

Hello, I am using Twenty Fourteen theme and have Smoother Slider as my slider, when I use feature image the size fits the full screen, when I use the slider it is too small and doesn’t extend to full page width or height see https://www.expressivephotos.asia to see what I mean. I am using a static page and adding in a page the has the reference to the slider in it, slider works and fits in preview mode but Not within the main page. Does anyone know how I get the slider to fill the screen please?
