type: item
description: I heard about this high definition TVs having two sets of resolution; the 1080i and 720p. What are these two pests mean actually? How do they differentiate from the older versions of television that we used to have?

description: The 1080 and 720 refer to the vertical resolution used - standard TVs I believe are 625. The i refers to interlaced - the same system that standard PAL uses where on one pass every other line is done, eg lines 1,3,5,7 and then the second pass lines 2,4,6,8...etc are done. The p is for progressive - where all the lines are done every pass, giving a crisper, clearer picture.

description: I also have seen these features on the new TV's. What would you recommend then if I have to choose from 1080i and 1080p? How can check the difference between these 2 options?

description: 1080p is much better. It displays all lines in each frame, where 1080i only displays every other line per frame.
