I know some things about tv but know very little about computers. My friend is an expert in computer but knows nothing about tv. When we discuss about movie or image resolution, we couldn't communicate. For example, with computer let say you get 1024x768 image. That's the vertical and horizontal pixels right? But what happens when you play a movie on such a screen? When we talk about vcr, dvd, HDTV and the likes, we go into horizontal lines of resolution interlaced or progressive. How does that compare? If you freeze an image on tv from a 480i, 480p or 1080i source and so on, what resolution are we getting? Any help will be appreciated.
