Its kinda confusing most of those TVs support inputs of 1080 or 720 just fine, but it helps to think of what 1080 and 720 are they are just another way of talking of resolution 1080 is 1920 × 1080 and 720 is usually on 1366x768 then you get the difference between p and i. p is better than i but a 1080p is a rare beast to see as its not used by any of the hdtv providers i know of andHDTV movies are rarer than hens teeth, although when you see one its a jaw dropping site but youre only going to see it connected to a computer really, 1080i and 720p are actually pretty close the advantages and disadvantages tend to balance themselves out sometimes usually its not a problem as 1080i TVs are more expensive and 720p ones are much cheaper.
If you are confused i would read the wikipedia hdtv explanations its quite complicated i just think about the specs like i would a computer monitor rather than a TV.
