I may not have explained the problem correctly. Sorry.
Here is two screen shots from 27″ monitor:


Here from a laptop:


On mobile everything looks great.
Issue is header images are not responsive for desktop experience on monitors 25″ or more.
How do we change/fix?
FYI, I did change the header image on the home page doubled the resolution. I am leaving there until I hear back from you. My graphics person now thinks I am an idiot! :)
Thanks. We will start changing images. I believe we were worried about load time. As is, the page loads a little slower than I would like.
I thought the responsive was set. Did we do something wrong or do we have to change something when we add the larger images?
