Instructions
Turn off the Wii and disconnect the standard AV connection. Insert the gray, singular side of the component cable into the "Digital AV Out" port on the back of the Wii. Insert the green, blue and red prongs on the opposite end of the component cable into the green, blue and red component inputs on your television. Connect the separated white and red cables into the white and red AV inputs on your television.
Set your television to its "Component" video display mode. Instructions vary, but most televisions and remotes have an "Input" button which you press to cycle through the display modes. Turn on the Wii. After a few seconds, the Wii logo appears on screen.
Use the Wii remote to select the "Wii" icon on the bottom of the Wii Channel menu. Select "Wii Settings." Select the "Screen" button. Select the "TV Resolution" button. Highlight "480p" as the resolution and select the "Confirm" button.
