1080p is the maximum video resolution available to consumers for most video displays and disc players. The best way to get 1080p video into your system is to use a Blu-ray player as a source connected via an HDMI cable. Most of today’s better HDTV sets have a native resolution of 1080p, including LCD HDTVs, plasma HDTVs and most front-projection technologies, such as D-ILA, SXRD and DLP.
1080p has an aspect ratio of 16×9, and has 1,920 pixels in width and 1,080 pixels in height. The “p” stands for progressive, which means every 60th of a second all the pixels are displayed. Most cable and satellite boxes only output 1080i (for “interlaced”) but with film-based material there is no resolution difference between 1080i and 1080p. With fast motion video, like sports, native progressive content will generally look a little better.
