Hi
Add this code in custom.css file
.acm-slideshow .item {
background: none!important;}
.acm-slideshow .background {
opacity: 1;
}
it load in background so it will fill the text area.
If you will make it 100% width the image will not able to fill whole area.
you can try this this code
.acm-slideshow .background {
background-size: 100%;}
