As of January, 2011, television sets often feature three or more types of cable connector standards that you can use to connect other devices to the set. The different types differ in how easy they are to use and their performance abilities.
HDMI, or High Definition Multimedia Interface, is the simplest to use because it only needs a single cable connection for video and audio. Also, it supports full high definition display at the 1080p resolution.
DVI, Digital Video Interface, and VGA, Video Graphics Array, connection types are mostly used by computer monitors. However, many TV sets now feature these connection types. They support full HD, but they do not carry audio signals. If you want sound with DVI or VGA, you can use a separate audio cable.
The composite connection type is used for legacy support. Its supported resolution is sufficient for older devices manufactured before 2011.
Component cables resembles composite cables, but it supports higher resolution images. It uses the same style of audio connection as the A/V standard. It supports resolutions up to 1080i, but requires five connection cables.
Digital Optical Audio Connection
Digital Optical Audio is an audio-only connection type. It can be used to send audio from the TV to a sound system. It sports top-of-the-line sound quality.
RF, or Radio Frequency, is the oldest standard still supported by modern TVs in 2011. It produces low-resolution analogue video, but supports high-resolution digital video.
