Fullwidth Easy Slider Size In Mobile Version

Is there a way to change the size of the “Slideshow Image and Video Size” option, in a Fullwidth Easy Slider, depending on a media query?

In my case, I’ve set it to “Featured 1500×430” in the slider’s option. But due to the ratio of this image size, on a mobile device in portrait mode, the height is so small that the caption and button get “cut off”. I know that this is due to the image size, but maybe there was something I could do about it…

Thanks,
