RGB Format

To overcome the drawbacks of Composite video format, the two signals are conducted on two different wires in this format. The cross section of a Y/C cable reveals the it has four wires; one for Chrominance, one for Luminance and two for Ground terminal. This isolation of signals improves the quality of image appreciably. But this format requires a special connector on the monitor to accept this cable. It cannot be connected onto the BNC type of connector. Since the format uses more expensive circuitry and also is for higher quality of image that is not required in ordinary uses of TV monitor, ordinary monitors do not have any provision for accepting this format cable. Specially designed medical grade monitors are available to accept this format besides BNC format.
