You need to set two things - the image size and aspect ratio.
To set the image size you simply make an entry into your resolution.ini
file for the appropriate size (720p = 1280x72, 1080i/p = 1920x1080).
All HDTV compatible equipment should handle all three formats equally
well, so it's upto you which one you want to use (quality-wise there
isn't much of a difference as the 1080i/p formats have to make some
sacrifices to squeeze all that info into each frame).
But pixels in an HDTV image are not square (aspect ratio of 1), so you
need to tell povray to render non-square pixels. I'm not sure if there
is a more efficient way of doing this, but I always use the camera
command for this. You simply add the "right" command to the camera,
with the desired aspect ratio after the "right command. For HDTV this
is 16:9;
camera {
location <0,0,0>
look_at <0,0,1>
up y
right (16/9)
}
