    704×480 sampling preset does not necessarily cause aspect ratio error in itself since its sampling rate is correct for DC (858), but your display may scale 480p to 4:3 instead of keeping 1:1 PAR which then does. If the display supports VGA 640×480 timings, you can change 480p output preset timings to match that from output opt -> adv. display timing.
