- | ===== Nintendo GameCube Digital AV Connector ===== | ||
- | The DigitalAV connector carries digital sound and digital component video. | ||
- | There are other pages detailing the [[nintendoGCRGB|GameCube RGB + VGA]] and [[nintendoGCDA|Digital Audio]] mods on this wiki. | ||
- | |||
- | <box warning round|Caveats> | ||
- | * Most GameCubes have the digital connector, however to reduce costs Nintendo removed the port from newer systems. | ||
- | * The GameCube is capable of creating a progressive signal, however the software must support it. No PAL software utilizes the progressive capability of the hardware (so no VGA either). | ||
