How Do HDMI Cables Work and What Are They Used for?

With the computer and TV industry taking off to greater heights each year, it’s understandable why someone might not know a lot about newer HDMI cable standards. Although they have been in use for some time, the difference between HDMI and other types of audio/video cables is not always understood.

HDMI stands for HD High-Definition Multimedia Interface, and it refers to a type of standard used for connecting high definition devices. These can include anything from smart TVs to various older HDTVs and computer screens, as well as projectors, DVD players, BluRay players and much more.

HDMI cables work by transferring digital signals, unlike the analog audio and video signals that were used in the case of older TV sets. With HDMI, the information being transferred is also much vaster. While older digital and analog cables typically transferred standard definition images, HDMI allows for resolutions of up to 1920 x 1080 pixels featuring a wide screen image.

Because of this fact, it’s important that, when you use HDMI for example to put together your very own home theater, you have to make sure that all the components of your home theater are compatible with it. Failure to do so would lead to a significant dilution of image quality and resolution that would basically defeat the point of using the HDMI standard in the first place.
