Hot Full Carousel has full in its name for two reasons. The first, regardless if you have 3 or 20 slides, it rotates in the same direction all the time, just like a real carousel. The second reason are its responsive features. This is responsive carousel with responsive behavior (if used with responsive template). Actually, this module can have fixed width, but can also occupy the full width of the screen. This behaviour is maintained on both large monitor screens, tablets and smartphones. Of course, to make it happen, you must publish the module in module position that spans the entire width of the screen. Check your template about this.
