The Xbox 360 Component HD AV Cable comes bundled with most of the Xbox 360 console bundles. It works with both high-definition and standard TVs and also monitors.
1. Set the switch on the A/V connector for your TV or monitor:
If the TV is HDTV, High definition: set the output to HDTV.
Note: Set the switch to HDTV only if your TV or monitor supports a screen resolution of 480p or higher.
2. Connect the connectors on the component HD A/V cable to the corresponding color input jacks on the TV.
§ On a high-definition TV, if the cable has a yellow RCA composite video connector, it can be left disconnected.

3. Connect the A/V connector on the component HD A/V cable to the A/V port on the console.
