Slider Width

Hi, i am using a notable theme, here is its demo http://hb-themes.com/themes/notable_wp/

i tried several sliders, one by one slider, carousel and others but could not use to make sliders of this kind like you see on http://www.devicebee.com/

I could put buttons and text using one by one slider, but when i increased the width to 1600px or 100%, slider would not be extended in width, can anyone tell me on how to make a slider of this kind on devicebee, if there’s a code or any plugin for it??
