Full width in Slider Revolution

Basically ALL of your demos have full width photos using the Revolution Slider. Your demos also have the slider resize automatically when the browser window is resized.

I’m just trying to get THIS functionality which is obviously possible and shouldn’t be this difficult. But I can’t figure out where the Revolution Slider borders are in the editor. Images I insert do not use the full width, a dark space is always on left and right, not as your demos which occupy the full width of the screen.

I want my slider to automatically take up the FULL WIDTH of the entire page, even when resized.

How can be done?
