RGB cable is so because the connectors on the ends of the cables are color coded red, green and blue. There are a number of RGB cable. All RGB cables are a type of component video cables. Component video cable for video signals into three signals are routed. Two of the three signals that control how much red and blue in an image. It is called AS and RY component. The third signal is called luminance signal processing black-and-white information and controls the brightness of an image. He often described as the Y component. In contrast to composite cable, there is no compression of signals. For this reason, the color depth and resolution achieved better than composite video and even an improvement in the S-video installations.

RGB is still sometimes used in computers, but will be increasingly replaced by digital formats, Digital Video Interface Cable (DVI cable). Some of the many devices that use the RGB input and RGB cable and technology are color TVs, digital cameras and scanners. There are also several RGB output devices used frequently. These include computers, mobile displays, televisions with a variety of display products, such as cathode ray tube technology (CRT), liquid crystal display (LCD) and plasma TV or LED display, video projectors, and the big screen shows that as JumboTron are many sports and entertainment venues.

RGB Analog composite video signals must always be combined with another signal to function. One way this happens because the composite sync. In any form of representation, determines the resolution of the number of pixels which are arranged both vertically and horizontally on the screen as a computer monitor or a TV monitor. The number of vertical lines on the display is always solid. The vertical lines are also often called lines. But conversely, varying the number of pixels that can be between each vertical line. The number of pixels determines the horizontal resolution. Depending on the ability of the screen or display performance, quality resolution can be achieved varies. In this type of equipment, both horizontal and vertical signals are combined in an entirely separate thread. This type of synchronization is RGBS. A true composite signal resulting from the use of four wires. They are red, green, blue, and a connection for synchronization, usually white or yellow. Another way to combine the signals, is a separate sync. In a separate sync, horizontal and vertical signals are carried on a separate line. This type of synchronization used in RGBHV setup. Separate Sync, see the analog VGA devices such as the common computer monitors. Separate Sync requires five different plugs. They are color coded red, green, blue and either a combination of yellow and white, yellow and black or gray and black connectors.
