Ok, it's very simple. An LCD, Plasma, DLP, etc...TV cannot output an interlaced picture, it's not how they work. The will convert the image to a progressive picture because, they don't scan every other line every other screen refresh, they scan every line every refresh, make sense?
Thank you for the basic lesson, but I think most people already know that digital displays are fixed at either 720p or 1080p. I also think most people already know that whatever the source, the TV will up or downconvert to the TVs fixed resolution.
However, what I don't know is why you say 1080i is so much worse than 720p, especially when a lot of sources are broadcast in 1080i. So when you are sending a 720p signal from your cable box and watching a 1080i channel, you are first downconverting the source, and then upconverting it back to 1080p.
Either way, if you send out 720 or 1080 from your cable box, your TV will display 1080p.
