What are 720p, 1080i, and 1080p and what's the difference?
These are the names used to describe an HDTV's native resolution plus the resolution of content that is either broadcast on a disc, that is displayed on the HDTV. 720 or 1080 refers to the number of horizontal lines there are to fill the screen - the more lines there are, the higher the resolution.
Standard definition TV by comparison is much lower ersolution at 480i. HDTV manufacturers typically offer 720p/1080i and 1080p televisions. High definition cable/satellite and network TV broadcasters can deliver content at a maximum resolution of 720p or 1080i. Blu-ray can deliver full 1080p content. Your TV will automatically display the best quality it can, based on the content.
The "p" refers to progressive scanning while "i" refers to interlaced scanning. Progressive scanning is better than interlaced scanning and produces smoother video that stayes sharper particularly during fast moving scenes. 1080p which is also known as "Full HD" is the highest standard for HDTVs and content.
