YES! If I select *only* the native resolution option on the viewer, the distortion goes away. Thank you so much! While I could live with the distortion for toolbars and dialog boxes for Photoshop and such, the distorted aspect ratio still bugged me.
Spent some time with the Premiere program monitor window on my phone through you, and that worked fine, and was useful; pushing the tech harder than I had initially expected to, but figured it was worth a try, and it both worked, and was useful.
Good luck hitting your expected release without too much death march!
