Things You'll Need
Instructions
Connect the Wii end of your Wii-to-VGA cable to your Wii.
Connect the VGA end of the cable to your Gateway PC monitor.
Connect the audio (red and white) ends of the adapter to an audio output source, such as stereo speakers or a television.
Turn on your Wii and your Gateway monitor to test your signal. If need be, make sure your audio source is tuned to your RCA channel by pressing the "input" button on your audio device. The signal from your Wii should be seen on your monitor, with sound coming from your audio source.
