With the advances of technology, the home theater experience becomes more important. When going to an electronics retail store to pick out a TV or projector, a potential buyer is often overwhelmed by the sheer selection and sizes of TVs to choose from. Not only do TVs come in large or small sizes, there is also another factor that you need to be aware of: Screen Aspect Ratio, which is the relationship of an image’s width to height.

What Does Aspect Ratio Mean?

Aspect ratio is the relationship of an image's width to height, or its proportions. For example, a 4:3 display produces an image that is more square, where a 16:9 ratio produces an image that is more rectangular in shape. The most common aspect ratios are 4:3 and 16:9(standard HDTV). Which one do you like better? It probably depends on what you plan to playback.
