When I look at your site, the “stretch” setting is in there, but there is a max-width declaration of 1080px in the tag for the slider:
<div class="metaslider metaslider-flex metaslider-164 ml-slider" style="margin: 0px auto; max-width: 1080px;">
so that although the slider itself is set to take the full width of the display, those slides on your home page are set to go no wider than 1080 pixels.
That may be a good thing; if those images are 1080px wide, you wouldn’t want them to be scaled up to fit a larger display. They would be blurry.
You may find there is a setting for that particular slider, or for all sliders, that limits the stretch setting to the width of the source image size to prevent blurry images, or it may be built into the slider itself.
Vantage uses some JavaScript to change the max-width parameter from 1080px to 100%. Everything looks right, but you have a JavaScript error which could be stopping it from working. The JavaScript issue looks like its something to do with a Responsive Contact Form plugin – could you try disabling that?
Thank you everyone 🙂 I was able to solve the problem. Matcha Labs you were correct it was the Responsive Contact Form plugin causing the problem!
