This banner is set with a Mobile Image, which means the background image will change on a mobile viewport. Try changing the width of the viewport to see it in action.
This banner has no Mobile Image applied, but has the 'Hide background image on mobile' toggle set, which means the image disappears on mobile. Hopefully this gives you lots of flexibility!
