Connecting Wii & DVD Player to a TV with Only One AV Input

If your TV has only a single composite (yellow/red/white) AV input, you cannot plug both devices in simultaneously without a switch or converter. Here are the practical solutions, ranked by quality and convenience.

Best Solutions

1. AV Selector Switch (Cheapest, Keeps Analog)

Buy a manual composite AV switch box ($10–$20). Plug Wii and DVD player into the switch inputs; run one output cable to the TV. Press a button to toggle sources. No power required for passive models.

2. Wii2HDMI Adapter + HDMI Switch (Best Picture Quality)

• Wii outputs 480p via component; a Wii2HDMI converter ($15–$25) upscales to digital HDMI.
• If DVD player has HDMI, use an HDMI switch ($15). If not, add a composite-to-HDMI upscaler for the DVD player.
• Result: Single HDMI cable to TV, sharper image, modern input.

3. Component Video (If TV Supports It)

Many early HDTVs have component (YPbPr) inputs (red/green/blue video + red/white audio) plus one composite input. Use official Wii component cables for 480p on component; keep DVD on composite.

Quick Tips

• Wii Settings: Set Wii to 480p and Widescreen (16:9) in System Settings for component/HDMI.
• Cable Quality: Shielded cables reduce interference, especially for longer runs.
• Audio: Switches pass audio automatically; ensure TV speakers or external audio system is on correct input.

Avoid: Cheap "Y-splitter" cables merging two outputs into one input — they cause signal collision and potential hardware damage.
