HDMI

High Definition Multimedia Interface is the current gold standard of home theater cabling. Not only can HDMI cables provide perfect, uncompressed digital high-definition images at 1080p and 7.1 surround sound, they do it all with one cable. That means a high quality digital video and audio connection between your components as well as far fewer wires hanging out the back of your home theater. If your components support it, use it.

The HDMI standard is actually derived from the DVI standard, so some backwards compatibility between the two technologies exists. You will find DVI to HDMI cables on the market that will allow the connection of devices with DVI-only output to HDTVs, projectors and A/V receivers with HDMI inputs. Because DVI does not transmit audio signals, however, you'll require additional audio cabling if you're using a DVI to HDMI cable to transmit video in your home theater setup.
