slider with variables based upon mobile/desktop

Hi all, maybe I wasn’t descriptive enough, so I’ll try to be with this post.
I am using the Slideshow plugin.

I have worked with it, and have stumbled upon a problem that i’m not able to fix, or have received support for. so I’m looking for another slider that may do what I want.

I would like to have a slider establish a fixed height, and auto width, while in desktop mode, and have the images “stretch to fit”.
Here is the actual slider that I want in desktop mode.

Now in mobile mode, I would like to have auto height and width and “stretch to fit”, like this style. and also have the image properly proportioned so that the images don’t look skewed.

So the difference is: auto height while in mobile with proper proportion for image, and fixed height in desktop. does anyone know of a slider that can do that?

currently if you go to the test side via mobile, the slider does auto height and width, but its not properly proportioned and the images get skewed.

well i seemed to have solved the issue, now its just cosmetics, which i’m sure the plugin support area could solve hopefully.
