The original Wii does not have an HDMI output. To connect it to an HDMI-only television, use a powered Wii-to-HDMI converter that accepts the console’s analog AV output, then connect the converter to the TV with a normal HDMI cable. The adapter can convert and scale the signal, but it cannot create native HD detail that the Wii did not output.

A Cable Alone Does Not Convert Wii Video
| Part | Role |
|---|---|
| Wii AV output | Provides the console’s analog video and audio |
| Wii-to-HDMI converter | Converts the analog signal to digital HDMI |
| HDMI cable | Carries the converter’s HDMI output to the TV |
| USB power, when required | Powers the active converter electronics |
A passive cable with a Wii plug at one end and HDMI at the other cannot perform analog-to-digital conversion unless active electronics are built into the product. Check the signal direction and power requirement.
How to Connect a Wii to an HDMI Television
- Turn off the console and television.
- Connect the converter to the Wii AV port.
- Connect an HDMI cable from the converter output to the TV.
- Supply power to the converter if its instructions require it.
- Select the matching HDMI input on the TV.
- Open Wii System Settings and choose the supported TV resolution and widescreen setting.
Nintendo documents 480p as the EDTV/HDTV setting for compatible Wii connections. The converter and television must accept the selected signal. Do not assume an adapter advertised as 1080p output makes the game render at 1080p.
What Picture and Audio Quality to Expect
Conversion can make the Wii usable on a modern HDMI input, but scaling quality varies by adapter and television. Text edges, color and input delay may differ. Audio normally travels through HDMI after conversion; some adapters also expose a separate analog audio output.
A short normal HDMI cable is sufficient for this converted signal. The HDMI cable guide explains why buying the highest cable category does not improve a low-resolution source.
Fix No Signal, Wrong Colors or Missing Sound
- Confirm the TV is on the correct HDMI input.
- Reseat the adapter and HDMI cable.
- Test a known-good HDMI cable and TV input.
- Return the Wii to a compatible resolution setting.
- Provide the required converter power.
- Test the Wii’s original analog cable to separate a console fault from the converter.
Wii-to-HDMI Buying Checklist
- Explicit Wii input and HDMI output direction.
- Supported Wii video modes and TV output formats.
- Power requirement and included cable.
- Audio through HDMI and any analog audio jack.
- Return policy for display compatibility.
For another legacy console setup, see the PS3 HDMI guide; the PS3 differs because it has native HDMI output.
