1080p Info Guide

What is 1080p?
1080p is currently the highest of HD programing available for home viewing. When compared to 720p and 1080i, this HDTV standard displays twice as many lines of resolution at one time. And even if you`re not receiving a 1080p signal, your new 1080p television will upconvert the signal for an improvement you have to see to believe.

 

    Total pixels displayed (in millions) per second:
    55.3 - 720p - 1280x720 pixels at 60 frames per second
    62.2 – 1080i - 1920x1080 pixels at 30 frames per second
    124.4 – 1080p - 1920x1080 pixels at 60 frames per second

What's the "p" in 1080p stand for? is 1080p?
Progressive. This means the image is displayed in a single pass instead of two passes as with interlaced displays such as 1080i.

Common HDTV Resolutions
Note: In HDTV, interlacing is still used in order to fit all of the picture information into the bandwidth or down the cable line. Remember, though, if you’re not receiving a 1080p signal, your new 1080p television will upconvert the signal and display it progressively.

1080i: Interlaced ResolutionInterlaced - odd lines then even lines
The image you see on your TV screen is made up of hundreds (sometimes thousands) of tiny horizontal rows of individual pixels. These rows are called “scan lines.” To trick the eye into seeing motion, the image on your screen needs to show 30 frames per second. To reduce eye strain and completely smooth out motion, 60 frames per second is preferred. Due to technical limitations when the TV signal was developed, to achieve the necessary 60 frames per second, only half the signal was shown at a time: first all of the odd scan lines and then all of the even scan lines. Because the TV set switched these alternating sets of lines every 1/60th of a second, your eye “laced” them together; a process called “interlacing.” To denote this, an “i” is added to the end of the number of visible scan lines of image: 1080 lines shown interlaced are called 1080i. Interlaced video does have drawbacks: thin lines and text may appear to flicker, and fast-moving objects can become blurry.

1080p: Progressive ResolutionProgressive - all of the lines, every time
Because technology has advanced since the original signal was created, we can now show video at 60 frames a second without interlacing them. This is called “progressive scan” and displays all the lines of video progressively. Most current HDTVs display either 720 progressively-scanned lines or 1080 interlaced lines. A new 1080p television displays 1080 progressively-scanned lines. If you compare an older 1080i TV to a new 1080p TV, you'll find that the 1080p set has twice as many lines of resolution on the screen at any given time. Thus, a progressively-scanned image looks sharper and smoother than an interlaced one. And new high definition DVDs take advantage of this increased display capability. The best you can get with most standard DVD players is 480p, but with high definition DVDs and players, you'll be able to enjoy full 1080p quality.

Do I need a plasma HDTV to get 1080p?
1080p capability is not limited to plasma TVs. LCD, rear projection, and front projection sets are all capable of 1080p display.

Just how good is 1080p?
The high-end digital projectors in some of the world`s finest movie theaters use 1080p technology! The increased resolution of a 1080p television results in the sharpest, smoothest images possible. If you thought HDTV looked good before, it will blow you away when viewed on a 1080p television.
