Aspect ratio is a very important factor for not only DVDs, but also almost all kinds of video you would encounter in your daily lives. The most common forms of aspect ratio of a DVD are 4:3 and 16:9. In most cases, when you are burning a DVD, you will be asked to choose an aspect ratio from these two options. Although aspect ratio is crucially important for the video or the DVD, and a wrong aspect ratio could ruin the entire watching experience when you’re playing, a lot of people still don’t know which one to choose or how to change it. Today, let me explain to you the differences between the 2 different aspect ratios, and how to change a right aspect ratio of the DVD and how to set change the aspect ratio when you’re playing a video on your PC.
Part 1: Difference between DVD aspect ratio 4:3 and 16: 9
Technically speaking, aspect ratio is the relationship of the width of a video image compared to its height. As mentioned before, the two most common aspect ratios are 4:3, also known as 1.33:1 or fullscreen, and 16:9, also known as 1.78:1 or widescreen. Ther are also some other Larger aspect ratio formats, but they are used in the motion picture industry.
All the older TV’s and computer monitors you grew up with had the squarish 4:3 shape, which are 33% wider than it was high. 4:3 LCD monitors can display analog video signals that conform to NTSC and PAL standards, but they are not capable of displaying HD (high-definition) videos.
16:9 is the native aspect ratio of most high-definition LCD monitors and TV’s (16:9 and 16:10 are very similar). It is 78% wider than it is tall, and fully one-third wider than a 4:3 screen. 16:9 widescreen monitors are ideally suited to display HD video signals. Some models can also display SD (standard definition) video signals, but this will require some compromises.
Generally speaking, if your computer monitor or TV set are bought in recent years, and it looks more like wide than square, then it’s 16:9 in aspect ratio. If you have some old display devices, they could be 4:3 in aspect ratio.
