Video: HDMI®, Component, and More
If youre using a home-theater surround sound system as your entertainment hub, then you may need only one video connection on your television so that you can connect it to the sound system. But if the HDTV is to be the center of your configuration, then make a list of the devices you want to connect; for instance, set-top box, DVD or Blu-ray player, game console, network media player, and computer. Unless you use a switcher (which can create a new set of challenges), youll want to make sure that you have a connection for each one.
The best connection to use is HDMI®, as this digital standard offers the best fidelity and highest resolution. HDMI® stands for High Definition Multimedia Interface, and it uses a small, flat plug. The single cable can also carry surround signals, which reduces cable clutter by eliminating the need for separate audio cables. Newer devices support the more capable HDMI® 1.4, but this version is backward compatible with HDMI® 1.3 connections. You can also get an inexpensive cable that will connect an HDMI® port to a personal computers DVI port.
Your second choice for hi-def images is component video, an analog connection that uses three wires ending in red, green, and blue RCA connectors. A VGA connector can be a useful way to connect to a computer or laptop that doesn't offer a DVI connection. Use S-Video (a DIN multi-pin connector) or composite video (a yellow RCA connector) for standard-resolution devices such as older DVD players or camcorders.
