The display resolution of a digital television, computer monitor or display device is the number of distinct pixels in each dimension that can be displayed.
HD is a term that’s thrown around a lot these days, but what does it really mean? There is no one answer. We’re going to walk you through the different formats, and compare them to scale.
After this demonstration, it should make a little more sense. This will work best if you view this video full screen, at 1080p resolution.
This is 480p, this is how clear television was for years, and it’s also the resolution of DVD video. Most video in this format also has a 4 by 3 aspect ratio, and that’s why it’s not quite as wide.
Now let’s move up to 720p. This is the resolution provided by most satellite and cable companies, advertised as HDTV.
This is 1080p. This is the current standard video resolution. Presently, the majority of consumer and professional video cameras shoot at this resolution. It is also the resolution used for Blu-Ray Discs.
Lastly, this is 4K resolution. Essentially it is 4 times the size of 1080p. The professional cameras that shoot in this resolution also have increased latitude and dynamic range, making the raw footage far more versatile.
There are many digital standards and #resolutions– it’s important to know which ones are available to you, and best suit your needs.
