Default Question for HDTV gurus

I have directv HD boxes that can be switched from 480i through 1080i. If the tv is rated at 720p, will the picture get any better by having the box set on 1080. I keep getting messages to set to the highest level.

The best picture is obtained when seen at the display's native resolution.

Anything less and the display must 'invent' data to filling in for what is missing.

Anything more and the display must decide what data to drop.

I'm saying the display is making the decision but it can just as easily be made by the source, i.e. cable box, sat box, DVD player, etc.

Set your sat receiver to 720p.

Correct. 720p is probably slightly superior to 1080i as it is non interlaced.

Depends what your watching. 1080i has a sharper resolution when watching some of the early lame slow moving discovery chanel hd programs. But 720p will be superior when watching faster paced scenes such as action movies, sports and porn!

Correct. Interlace scan is better for depicting the illusion of motion, particularly where image latency is an issue as it is with LCD displays. Plasmas are faster, better for watching complex scenes in motion (sports, zebra trying to save its ass from a hungry tiger, etc ...).
