Axiom Home Page Forums General Discussion Technical Questions 720p or1080i

It's a fair question -- there were so many debates about whether 720p or 1080i was a better broadcast format, so...

Anyways, as pmbuko said you're generally best off feeding the TV with its native resolution to minimize the amount of processing along the way.

What makes the answer non-trivial is that the TV could conceivably be better than the cable box at converting from 480i/720p to 1080i -- in that case *if* there is an option to output whatever format the broadcast was in then that would be worth trying as well.

If the box outputs HD at broadcast resolution (ie 720p programs are output at 720p and 1080i programs are output at 1080i) and your choice only affects what happens with SD(480i) broadcasts then definitely go with 1080i.
