DVI to HDMI Converter Cable

DVI ports are rarely if ever found on new pieces of computer and audio/video equipment. Source devices and televisions built before 2004, however, often have them and need to be connected to newer devices. Many audio/video receivers are used as system hubs, with all A/V source devices connecting to it. From there, the signal is switched and routed to a compatible display. You need an adapter if you want to connect an upconverting DVD player or older digital tuner to a newer A/V receiver.

Since DVI does not carry audio, the adapter cable will not either. The adapter device internally converts the wiring so that the output of the source device matches the input of the television or receiver. Put simply, the adapter cable changes the shape of the connector from one end to the other, not the signals carried on it.

DVI uses a computer-style connector, employing two threaded posts. Once the DVI connector is pushed into the associated jack on the source device, these posts must be rotated clockwise to seat the cable firmly. The process is identical to connecting a computer to a monitor. At the other end, an HDMI cable simply slides into place. Match the shape of the HDMI connector to the port on the display or A/V receiver and push it straight in.

DVI and HDMI are capable of identical video resolutions, ranging from standard 480i to 1080p. The limiting factor with this video capability is hardware based, since some devices do not allow 480i over a digital cable. Run a separate audio cable alongside the DVI to HDMI adapter cable to enjoy high-resolution images with digital sound.
