O.k, what is 1080P? 1080P refers to the amount of lines that make up a screen, and this image right here is very sharp and very crisp because there's one thousand eighty lines of progressive scanning on this screen. 1080I refers to one thousand eighty lines of interlace scanning, one line after another, not a constant scan. So, the 1080P gives you more scanning per screen than the 1080I which gives you a sharper picture, which is also better than 720P, which is just fewer lines, 1080P is great for Blu-Ray DVD reproduction. Hopefully, someday cable signals will be coming out in 1080P also, right now 1080I is the maximum for a cable signal or a satellite signal. Your standard definition televisions are either 480I or 480P resolution, so you can see there's a lot fewer lines that make up your standard definition television image, making 1080P a lot better picture.
