Hi,

Try to edit your WPBakery column that contains slider and add this CSS class to it custom-slider-width. Then, put the following snippet to the custom CSS area

@media(max-width: 1200px) and (min-width: 1024px) {

.vc_row .custom-slider-width {
	margin-left: 270px;
	width: calc(100% - 270px);
}
}

Regards
