HDMI backwards compatibility

HDMI and cable run distances

Can you run HDMI cables over a long distance? This is an important question in many situations, but especially for organizations that want to use HDMI to connect projectors, which are often mounted on the ceiling of the room, with playback devices that are often a significant distance away. One of the nice features about HDMI cables is that they are built with standard copper cabling frameworks, so you can freely extend them up to 10 meters without any problems. Getting beyond 10 meters - extenders and built-in equalizers There are two primary ways to extend HDMI beyond 10 meters. The first is through various extension methods. Because HDMI uses standard copper cabling you can use CAT 5 or CAT 6 wiring, or even fiber if you are willing to deal with signal conversion, to go past 10 meters. Built-in equalizerscan be an easier option if you only need a few extra meters. Some endpoints, such as televisions and projectors, feature built-in signal equalizers that maximize the strength of the signal moving over the cable and make it possible to extend the signal beyond 10 meters without too much trouble.
