VGA to RCA adapters are used to output video from a computer to a standard definition television screen. The adapter must be used because standard definition televisions use RCA as a video input and do not contain VGA ports.
A VGA to RCA adapter can only be used if the computer's video adapter supports TV-Out through the VGA port. If so, the computer must be turned off, disconnecting the monitor from the VGA port and then connecting the VGA cable to the computer's VGA port. The user should connect an RCA cable to the video output port on the adapter cable. The other end of the cable is then connected to the television input.
The television and computer should both be turned on. The user then directs the remote control to select the video input of his television. The computer screen monitor should then appear on the television.
