The Nintendo Wii is a popular video game console that allows users to interactively play video games. Many people who own the Nintendo Wii also own a High-Definition Television (HDTV). These televisions allow users to connect to external devices and display high-definition video if the external device is able to display high definition. Typically, external devices are connected to the HDTV through the use of an HDMI cable. However, the Nintendo Wii does not have an HDMI output. You can, however, use a component cable (5 input jacks) to connect the Wii to your HDTV. This will display a sharper picture than the traditional RCA cable (3 input jacks).
Turn off both your Nintendo Wii and your HDTV before connecting the Wii to the TV.
Connect your component video to the inputs of your HDTV. A component cable has 5 input jacks, three of which are dedicated to video. Insert the green cable in the green jack. This should be labelled "Y" on the back of the television. Insert the blue cable into the blue jack labelled "Pb" or "Cb." Insert the red cable into red jack labelled "Pr" or "Cr."
Connect the component audio into your HDTV. There should be two remaining plugs left that are red and white. You can distinguish the red audio plug from the red video plug because the video cables will be grouped together and the audio cables will be grouped together. Insert the red audio cable into the red audio input jack on the TV. Insert the white audio cable into the white audio input jack.
Connect the other end of the component cable into the Wii. There should be a single input that slides into the A/V output slot.
Turn on both your Nintendo Wii and your television.
Select component input from your HDTV. You should be able to use your HDTV controller to scroll through the various input options.
Connecting the Wii with component cables will not be true high-definition video, but it will be a higher-quality image than the picture attained with a traditional RCA cable.
