What are 720p, 1080i and 1080p HDTV Resolutions?
High definition television (HDTV) is the highest form of digital television. It has a 16:9 aspect ratio, which is similar in appearance to a movie theater screen. HDTV has a couple of advantages over the old analog TV format — the wide screen and the resolution. The wide screen is good on our eyes — we see the rectangular wide screen images better than the old square format. Basically, our eyes see better from left/right compared to up/down. The wide screen will also let us see more of the on-screen scene, which is great for sports and movies. Resolution is undoubtedly HDTVs biggest selling point. HDTV’s resolutions are 720p, 1080i and 1080p — the number stands for the number of lines that create the image and the letter describes the type of scan used by the TV to display the picture. Resolution matters because the more lines means a better picture. This is a similar concept to digital photos and how dpi determines print quality. Which HDTV Format Is Better — 720p, 1080i, or 1080p
