What Are My Screen Choices for DTV Sets?
Your choices are: Flat Panel, Rear Projection, Cathode Ray Tube (CRT), or Front Projector. Most digital TV sets are wider, but not as tall, as analog sets of the same diagonal screen size (Note that all TV sizes are measured diagonally across the screen). Most digital sets have an aspect ratio of 16×9, while analog sets have an aspect ratio of 4×3.
