About DVI to HDMI Cable
DVI (Digital Video Interface) and HDMI (High-Definition Multimedia Interface) are two different cabling systems for connecting devices to monitors, TVs, projectors, graphics cards and other similar items. The major difference between the two standards is that DVI is not capable of carrying an audio signal, and this often leads to a situation where the user has a TV/monitor that only has one of the two connectors. In this situation, a DVI to HDMI cable is required that will convert the signal from one format into the other.
Different lengths of these cables are available, and this can be extremely helpful when dealing with a projector setup. For example, if a computer is only capable of outputting a DVI signal, and a projector can only handle a HDMI input, these cables can be run the necessary length to have the projector attached to the ceiling. Most TVs will also only have a HDMI input, which makes these cables essential for attaching a computer to these larger screens.
For more general cabling needs, complete kits of audio and visual cables are available that allow the user to get around the issue of DVI not being able to handle audio. For example, finding a kit with a 3.5mm to 3.5mm lead (headphone jack size) will often allow the audio signal to be carried separately to an external device. Composite audio leads (white/red plugs) will also do the same job, and the audio signal can then be fed into a hi-fi system or similar music equipment.
