IIRC, the beta versions ran at a 1920x2160 resolution and just stretched the picture horizontally to get 4K. Wouldn't surprise me if the One X is able to maintain a proper 4K a lot of the time (albeit probably with some dynamic scaling involved), while the Pro ends up running at something in-between like 2560x2160.
