Resizing for different screen sizes

I’ve been very happy with Master Slider, particularly the slider with Horizontal Thumbnails. It displays my work just how I want it.

Everything looks great on my 1920 x 1080 px screen, and resizes really well for the mobiles I’ve tried, and the ipad I’ve got.

The problem is, on my roommate’s 11″ macbook air 11″ , you have to scroll down to view both the image and the horizontal slider. Is there a setting somewhere that I’m missing that will resize things so that everything fits on one screen without scrolling?

I’m a novice with all this, and realize it might not be possible to have one style fit all different displays. The transition from 1920×1080 to mobile to tablet worked so well, I hoped it would be as smooth with notebooks as well.

Thanks!
