You can set up the slideshow to display on whole window width.
First of all, you need to choose proper module position in your
which is 100% wide.
If you are not sure if there is such module position you can contact your template provider.
If you are using
Joomla templates based on EF4
then you can set the full window width for template block in the layout builder and then publish the module in the module position of this block.
If you have the full-width module position then you just need to create the
module in this module position.
Next set the dimensions of the slides to some huge values, e.g. 1920 x 900. Note that the size you set in the module settings is the maximum size and the slideshow will be scaled proportionally for smaller screens.

You can set image resizing type as you need, however, to make the image always 100% width you should use a crop or fit to width option.
