Shifting Main Slider Image Up

How do I move the main picture of the monitor and mouse so that you can see the mouse on larger screens? The positioning of this picture and text is fine on phone, ipad, but it would look better if you could see mouse on larger screens. The trick is to move picture up without moving green rule, button or text.

Any input would be greatly appreciated. tx.
