Should I set my receiver to 720p or 1080i

I just purchased an HDTV several months ago and am trying to get the basics down so I have a few questions. I have a Toshiba DLP with 1280x720 mirrors; I assume that means my native resolution is 720p.

Ok so I think what that means is that if my TV receives a signal other than 720p it must convert the signal so that my TV can display it. Is this correct?

So in that case I should set my receiver (921) in the setup menu to 720p. This will make the 921 do the conversion to 720p not the TV. Is this correct?

My Xbox 360 can display 720p or 1080i so I should also tell the Xbox that my TV doesn’t support 1080i so that the game outputs the 720p version to the TV and it will perform better because no conversion is necessary. If I tell my Xbox that the TV supports 1080i and the games supports both 720p and 1080i the Xbox will output 1080i and my TV will have to convert to 720P. Does this sound correct?

Thanks

Don't over analyze it, your display will do the right thing.
Try both settings for the best picture. Has more to do with the quality of the deinterlacer in the receiver (or lack thereof). Many of us with Dish 811s find 1080i works best with our (majority) 720p displays.

I suspect 720 on the Xbox will work just fine.

Correct. There is no sense to xbox generate more detail than TV capable to show, better spend those resourses for frame/s.

Teoretically eighter receiver or TV can do conversion 1080i->720p better.
Just test both. Probably you will see no difference, in that case use coin to select.
