You can connect a GameCube to an HDMI-only TV using a simple AV-to-HDMI converter or an all-in-one HDMI cable made for classic consoles.

1. Connect the console’s yellow (video) and red/white (audio) plugs to the converter’s RCA inputs.
2. Run an HDMI cable from the converter to an open HDMI port on your TV.
3. Power the converter via USB (many include a USB cable; a TV USB port or a small USB power adapter can work).
4. Switch your TV to that HDMI input.
5. If the image looks stretched, use the converter’s 16:9/4:3 switch or your TV’s aspect setting.

Some solutions are a single cable that plugs into the console and outputs HDMI directly. Picture quality and stability can vary by converter and TV.

Look for a converter that matches the GameCube’s analog output and your TV’s HDMI input. Helpful features include:

• RCA inputs: Yellow video and red/white audio labeled “Video/L/R.”
• HDMI output resolution: Support for 720p or 1080p upscaling to match modern TVs.
• Aspect control: A 16:9/4:3 switch to avoid a stretched picture.
• USB power: Many units need USB power; check if a cable is included.
• Compatibility: Some models also work with other classics (e.g., N64/SNES), which can be convenient.
• Included accessories: You may need a separate HDMI cable if one isn’t provided.

Any of these options can help bridge the GameCube to HDMI. Actual image quality and latency can vary by converter and TV settings.

Most newer TVs only accept HDMI, so you’ll typically add a small converter between the GameCube and your TV.

• Use an AV-to-HDMI converter: Connect the GameCube’s yellow/red/white plugs to the converter, then HDMI to the TV.
• Power the converter: Many run on USB power from the TV or a USB adapter.
• Expect upscaling: The converter outputs 720p/1080p, but original games were designed for older displays, so sharpness will vary.
• Set the right aspect: Choose 4:3 on the converter or TV to maintain correct proportions.
• Alternative: If your TV still has composite (RCA) inputs, you can use the original AV cable instead of HDMI.

Results can differ by TV and converter, so minor adjustments may help.

Smart features don’t change the hookup—treat it like any HDMI TV.

• Converter or cable: Use a GameCube-compatible AV-to-HDMI converter (or a direct HDMI cable for classic consoles).
• Power: Many converters need USB power; a TV USB port can be convenient.
• Ports management: If you’re short on HDMI ports, an HDMI switch can connect multiple devices to one input.
• Audio options: If you prefer external speakers, an HDMI audio extractor can provide optical or 3.5 mm audio outputs.
• Input selection: Choose the correct HDMI input on your TV and adjust aspect ratio if needed.

Audio can travel with video over HDMI once the converter is set up.

1. Plug the GameCube’s red/white audio connectors (and yellow video) into the converter’s RCA inputs.
2. Connect HDMI from the converter to your TV and power the converter via USB.
3. Select the correct HDMI input on the TV and raise the volume.

• No sound? Check that the RCA plugs are fully seated, the converter is powered, and your TV speakers aren’t muted.
• External speakers: Consider an HDMI audio extractor to split audio to optical or 3.5 mm, or use a converter with a headphone jack if available.

Audio behavior can vary by TV and converter, so small setting tweaks may help.
