Both 1080p and 1080i each offer 1080 lines of vertical resolution, so they both offer an amazingly clear picture.
The difference is that 1080i is "interlaced." This means that each time a single frame of video is sent to the screen (60 frames per second in an NTSC signal) the monitor only paints every other line of the image (540 total). The next frame fills in the other 540 lines. And so on, back and forth. Whereas with 1080p ("progressive"), all 1080 lines are painted during every frame.
Since this happens so quickly, the human eye can hardly detect the difference, except perhaps for a barely perceptible "flicker" with 1080i. However, when watching very fast motion, like sporting events, it could become more noticable and even a bit fatiguing to the eye. For that reason, many people prefer watching sports in 720p versus 1080i, despite the lower resolution.
And as others have said, practically nothing is broadcast in 1080p yet, so as of now it's a non-issue.

It depends. For instance there is nothing delivered "over the air" in 1080p, because it requires sending too more information at once than the proposed bandwidth can handle. Having 1080p to watch football will be useless for instance. At best you can see it at 720p. 1080i is shown "over the air" for most movies. 1080p can only be found in some video games and some HD/Blue Ray DVDs. The P means progressive scan, which prevents blurring and "ghosting" in fast moving objects. Terminator 2 and the latest action games will look better in 1080p than 1080i if you have good eyesight and if it's on a HD DVD. If it's over the air, then it will be only shown in 1080i or 720p.

In theory it is 1080p
1080p resolution--which equates to 1,920x1,080 pixels--is the latest HD Holy Grail. That's because 1080p monitors are theoretically capable of displaying every pixel of the highest-resolution HD broadcasts.

In reality almost ALL HD broadcasts are in 1080i and 1080p is for DVD (HD or Blu Ray) or computer video (including video games). Looking at the picture I doubt if you can see the difference

1080p(innovative test) is greater helpful.. 1080p high quality is exceptionally much double that of 1080i or 720p (what you could see popular HD on television in). exceptionally much quadruple that of 480i, what you could see on a customary television set. 10 circumstances that of the qulity of the classic bunny-ear antenna.
