HDTV Resolutions

My god, this stuff has my head spinning. Is it possible that someone here can explain what the difference is between all these? I hear someone say that HD programming is best in 1080i, and others say that 720p is better.

I have a Toshiba 51HX83, bought last year, with HD through Cox Communications. I'm just trying to figure out my best settings as my digital cable box fried today, and installed my new one, but forgot to note what settings I had on the cable box before uninstalling the bad box.

So, you tv guru's out here, how are settings and resolutions on your tv with HD?
 
1080p is currently the best offered.

16x9 is widescreen aspect ratio
4:3 is full screen aspect ratio

set your box for 720p should be best.

720p works too.
 
Its technically best to watch in the original format of the signal. Different stations broadcast in different ways. Some use 720p and some use 1080i.

If there is a bypass setting on the cable box this would allow your TV to use whatever the original source is

Otherwise, the difference will be small, but I would select 1080i. Seems to be better compatibility wise.

Your TV will simply take 720p signals and display them in 1080i
 
1080i is 1920x1080 resolution INTERLACED in 16:9
720p is 1280x720 resolution PROGRESSIVE SCAN in 16:9

If you don't know the difference between interlaced and progressive, you should search on it. Too much typing.

I used to own a similar TV to yours and Toshiba's work best with 1080i but also accept 720p signals and convert it to 1080i (it cannot display 720p natively, only 1080i).

You shouldn't have to change any settings on your TV. Just plug it in via component cables and it will autodetect the signal. Make sure the "picture size" setting is at "Full" for 16:9 material.
