Full-width footer for widescreen

Site URL: https://www.thatspeakmtb.com

Hey guys! I am looking for some help with my footer. I have both a 15inch macbook and a 27inch imac. The footer looks great on the macbook but on the imac it isn't stretching to fill the wide screen. I have played about with some code and I can't seem to get it to stretch to fill the widescreen. 

Attached is an image to show what is happening.

Many thanks 🙂

Footer has 1900px limit width. You can add this to Design > Custom CSS to remove it

/* Footer width limit */
div.Footer-inner {
    max-width: 100% !important;
}
