RGB Cable

RGB Cable

Anachronisms have never been as widely used as they are today, it appears that any three or four letters in any sequence mean something, as if saying the entire word sequence would simply take too much precious time.

Just as no one says the Federal Bureau of Investigation any more, FBI just seems to roll off the tongue much easier, thus it is with RGB cable, for RGB cable is saying that the cable is made up of three different colors, Red, Green and Blue.

Any digital video device whether we are speaking of computer monitors, or digital cameras and even most game machines rely on RGB signals and thus support the RGB format. So, cables that deal with these digital video devices also require the use of RGB cable.

As mentioned, your computer monitor is using RGB signals. An RGB monitor consists of a vacuum tube that has three separate electron guns, one each for Red, Green and Blue, at one end with the screen at the other end.

These electron guns fire said electrons at the screen. The screens contain a phosphorous coating, thus when those phosphors become excited due to the electron beams they are receiving, they then glow.

If the red beam hits them, they will glow red, and so on with green and blue. This makes each pixel on the screen be a combination of those three colors. The colors are, of course, carried on a RGB cable.

Most RGB cable connections use three pins, one for each color, thus let’s say that you are connecting your laptop computer to a projector to enable you to make a computer presentation to your colleagues.

In order to make this connection there is going to be a RGB cable involved. If any of the pins on the cable are broken, bent or otherwise broken, by say being pushed in, the connection will be broken. Each pin is as important as the other.

Today, the need for RGB cable connections grows steadily, for instance in those Home Theater connections, RGB cable is needed. Depending on what you need to connect, often you’ll find that RGB cables are sold in six foot lengths, however they do come in much greater lengths depending on your specific needs.

Most RGB component video cable is actually hand-crafted in order to meet precise guidelines so that they will prevent noise interference while optimizing the conductor contact in order to achieve the best possible image.

You may have noticed that the connectors are gold and the wire between them is made of high-grade coaxial wire. This is to guarantee optimal picture fidelity, even in HDTVs.

Those cables are specifically designed for component video signals, which use a distributed Luma/ChromaR/ChromaB signal, denoted Y/Cb/Cr. So, if you desire to convert the component to a VGA-compatible Red/Green/Blue signal, you then will undoubtedly need a component to VGA converter.
