Things You'll Need
Instructions
Connect an RCA or component video lead for Nintendo Wii to the "AV Out" port at the back of the console.
Connect the video and audio plugs for your lead to the color-coded plugs in the back of your television. The white and red stereo plugs can also connect to the "Aux In" ports of a stereo system for an improved audio signal.
Turn on the Nintendo Wii and tune your television to the "AV In" or "Video In" channel. Select the round "Wii" icon in the bottom-left corner of the screen by pointing your Wii remote controller at the icon and pressing "A."
Select "Wii Settings" then "Screen." Choose "Widescreen Settings" and select "4:3 Standard" if using an RCA cable, or "16:9 Widescreen" if using a component video cable on a widescreen HDTV.
Point your remote at the "Confirm" button and press "A" to complete setup.
