Layerslider background resizing on responsive (reduced screen size)

Hi,

On the Advanced Layerslider I am using a background image whose dimensions are smaller than the actual background size:

– Background size: 1600×470
– Background image size: 800×235

I then let the browser stretch the image. I am doing this to reduce background image size, and the reason I can do this is because the background image is gaussian blurred anyway so the browser stretching the image has no negative visual side effects.

The problem is than when you reduce the browser screen size to iphone/ipad-like dimensions, the background image at some particular window size suddenly shrinks and is no longer stretched by the browser to fit the slider ‘window’.

Please can you assist?
Thank you!
