1080i vs 720p

Agree, 1080i is noticibly better than 720P on my display (Pioneer Elite Kuros 60"). When sporting events are transmitted in 720P, it is actually dissapointing, to me.

"no flat panel TV today actually displays a 1080i signal. They all buffer 1080i and display 1080p."

True, but if they would then 720p should be better in spite of lower resolution, since eye is extremely sensitive to horizontal misalignment.

I would think 720 P theoretically, than, should equal 1440i, but it doesn't. Inherent limitations of bandwith, and time, if I am not mistaken?

Sorry but the last 2 posts don't make any sense to me.

I don't agree that "no flat panel displays 1080i...". Mine does. Precisely. As for my post, I don't agree that a progressively scanned signal is half of the intelaced. Resolution isn't that simple. To me 720 P is a knock off of 1080i (due to transmitor not wanting to pay for the bandwidth and, perhaps, actually thinking a 720 progressively scanned image is better than a 1080 scanned interlaced image-fox network comes to mind); until 1080P, 1080i was the puresst hd resolution. I am not dismissing the advantage of a progressively scanned image, just the size of bandwith it travels in.
