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. On paper, they should offer more than twice the resolution of today's 1,280x720, or 720p, HDTVs, such as Samsung's HL-P5085W. Some companies, such as LG, refer to these super-high-res of sets as ultra-HD, while others prefer to substitute true or full for ultra.

2. Why 1080p is theoretically better than 1080i
1080i, the former king of the HDTV hill, actually boasts an identical 1,920x1,080 resolution but conveys the images in an interlaced format (the i in 1080i). In a tube-based television, otherwise known as a CRT, 1080i sources get "painted" on the screen sequentially: the odd-numbered lines of resolution appear on your screen first, followed by the even-numbered lines--all within 1/30 of a second. Progressive-scan formats such as 480p, 720p, and 1080p convey all of the lines of resolution sequentially in a single pass, which makes for a smoother, cleaner image, especially with sports and other motion-intensive content. As opposed to tubes, microdisplays (DLP, LCoS, and LCD rear-projection) and other fixed-pixel TVs, including plasma and LCD flat-panel, are inherently progressive in nature, so when the incoming source is interlaced, as 1080i is, they convert it to progressive scan for display.

3. What content is available in 1080p?
Really, nothing at this point. Today's high-def broadcasts are done in either 1080i or 720p, and there's little or no chance they'll jump to 1080p any time soon because of bandwidth issues.

There Is No Difference Between 1080p and 1080i
My bold-printed, big-lettered breaker above is a little sensationalistic, but, as far as movies are concerned, this is basically true. Here's why. Movies (and most TV shows) are shot at 24 frames per second (either on film or on 24-frame-per-second HD cameras). Every TV sold in the United States has a refresh rate of 60 hertz. This means that the screen refreshes 60 times per second. In order to display 24-frame-per-second content on a display that essentially shows 60 frames per second, you need to make up or create new frames. This is accomplished by a method called 3:2 pulldown (or, more accurately, 2:3 pulldown). It doubles the first frame of film, triples the second frame, doubles the third frame, and so on, creating a 2-3-2-3-2-3 sequence. (Check out Figure 1 for a more colorful depiction.) So, the new frames don't have new information; they are just duplicates of the original film frames. This process converts 24-frame-per-second film to be displayed on a 60-Hz display.
