Video Cables: Types and Functions


video cables

Electronic displays usually have various input ports; this is to facilitate connections for the different video connectors that are prevalent. Here are the various types of video cables. You can simply key in the cable type or name on search engines, such as “best HDMI cables” or “HDMI to DVI cables” to look up options.

Composite cables

These are made for standard definition connections. They usually have three wires in separate colors- yellow, white and red. The yellow wire is meant for the video, while the white and red wires are meant for the right and left audio systems respectively.

Component cables

These cables offer HD connections between devices. They are usually made of three individual color-coded wires. These individual colors on the wires are to be connected to ports with corresponding colors, which makes for easy identification and setup. These cables are video-only cables, and necessitate the requirement for separate audio cables.

S-video cables

These cables are built for standard definition videos. The picture performance is better with these cables when compared to composite cables. They require separate cabling for audio devices.

HDMI cables

HDMI or high definition multimedia interface cables connect HDTV to converters and are made for high definition programming. These cables are not the sole option to facilitate HDTV but have a number of benefits. For instance, they carry both audio and video signals, so you won’t need individual cables for both. Also, the latest laptops and PCs have HDMI provision which allows users to project the monitor of the device on the TV.

DVI cables

DVI or Digital Visual Interface cables are typically for computer monitors. In fact, you will notice DVI ports on older versions of HDTV which won’t have HDMI ports. You will need separate audio cables if you’re using a DVI cable for your device.

HDMI to DVI cables

These cables have HDMI connection at one end and DVI connection on the other. They find their use in situations where a HDMI connection is required for a device which does not have the corresponding port. Say you have a HD converter, you can connect it to a HDTV without a HDMI port, but only a DVI port, with the help of a HDMI to DVI cable.
