How to adapt full width parallax images on mobile?

When using parallax section with a full screen image then it does not scroll on mobile - which might be ok. But it also gets cut in portrait view which makes the image completely ugly.
How can I ensure to have the image in full width with adapted hight, no matter how big my screen is?
