Layout issues on iPad

Hey, I just created a site with Parallax Frame and it looks really good - everywhere except on retina iPads in landscape format. Desktop view: iPad header: iPad body: I've been messing around with all the screen size settings I could find in the style.css file, but I can't figure out what part of it the iPad is using. Can anyone help me, please? I really don't want to have to configure a different theme because of this.
