Initial load the images, the sider li does not fill the entire screen width..

[hughred22]

So my images are 1400px in width. When the page load, if the browser windows is more than 1400px, let's say 1550px, I can see part of the second image on the right. The slider does not responsive to fill the full width. But when I scale my browser windows a lit bit, then the slider scale to full width and the height change as well. How can I make sure the calculation of the width of the slider happen at the end of ng-repeat or what not to make sure when the slider finish loading, it is fill the entire screen width instead of just the images width?
