Images, Launchscreen.storyboard and Autolayout

First off, I hate Autolayout… And for the code and UI part of all of my apps I manage quite well with out it.

However, for a Launchscreen.Storyboard you have no choice, you must use AL

What I need is rather simple (or so I think). I have an image… with a physical size of 1334x320. All I want to do is to display it across the top of a Landscape view, locked to the left and right… So it fills the WIDTH of the device (regardless of which one), and maintains the proper aspect ratio.

No matter what I do, it displays at what seems to be 1024x228 on all devices… this is the correct adjusted size for only the 9.7" iPad

Anyone able to help here?
