Connect your Wii to a smart TV using its yellow, white and red AV cable if the TV has matching inputs, or use a compatible HDMI adapter or powered converter and select the connected TV input. Then connect the Sensor Bar and pair your Wii Remote to operate the console.
Nintendo says the original Wii has no native HDMI connection, so a passive cable cannot replace analog-to-HDMI conversion. Check your console model before buying an adapter because Wii mini requires a composite-compatible connection.
The short version
- Matching AV sockets: Connect yellow to video, white to left audio and red to right audio.
- HDMI connection: Use a compatible Wii HDMI adapter, powered converter or gaming upscaler.
- Wii mini: Choose direct composite, a compatible AV breakout adapter or composite-to-HDMI conversion.
- TV source: Select the AV or HDMI input matching the connected port.
- Remote setup: Connect and position the Sensor Bar, then pair the Wii Remote when needed.
Choose the connection that matches your TV
| Connection | What you need | Compatibility and limits |
|---|---|---|
| Direct composite AV | Wii AV cable and TV composite inputs | Wii and Wii mini |
| AV breakout adapter | Wii AV cable and TV-compatible adapter | Wii and Wii mini; adapter must match the TV model |
| MAYFLASH W016 HDMI adapter | Adapter and HDMI cable | Component-capable Wii only; no upscaling |
| Composite-to-HDMI converter | Wii AV cable, powered converter and HDMI cable | Wii and Wii mini |
| Component-to-HDMI converter | Wii component cable, powered converter and HDMI cable | Standard Wii only; PORTTA RHX passes resolution through |
| RetroTINK-5X Pro upscaler | Compatible analog cable, processor and power supply | Standard Wii through supported inputs; Wii mini through composite |
| ElectronAVE internal modification | Professional installation and mini-HDMI connection | Standard Wii revisions; excludes Wii mini |
| Wireless HDMI extension | Compatible Wii conversion plus transmitter and receiver | Conditional compatibility; added latency can affect play |
Check the TV’s input labels for composite AV sockets, an AV adapter connection or HDMI inputs. For an HDMI-only TV, choose a Wii-specific HDMI adapter, a powered converter or a gaming upscaler that accepts your console’s output.
Before buying a converter, check its direction and supported input formats: the Wii’s analog signal must go into the converter, with HDMI coming out toward the TV. A component-to-HDMI converter and a composite-to-HDMI converter accept different video signals, even though both use color-coded plugs.
Connect the Wii directly to AV inputs
With the equipment off, plug the Wii AV cable into the console’s AV Multi Out socket, or into the AV Out connector on Wii mini. Connect yellow to the TV’s composite video input, white to left audio and red to right audio. Turn on both devices, press the TV remote’s Input, Source or TV/Video button, and select the connected AV input.
Some TCL Android TVs and other televisions use an AV breakout adapter instead of three full-size sockets. If your TV’s manual specifies one, connect its supplied or model-compatible adapter to AV IN, then connect the Wii cable’s yellow, white and red plugs to the matching sockets. Connect the cable’s console end to the Wii, power on both devices and select the TV’s AV input. Use the adapter specified for your TV model.
Use a Wii HDMI adapter for an HDMI connection
For a standard Wii, a compatible plug-in adapter connects the console’s AV output to an HDMI cable. Insert the adapter into the Wii, connect its HDMI output to the TV, power on both devices and select that HDMI port. ElectronWarp and MAYFLASH W016 are two options, and both exclude Wii mini.
You can get the ElectronWarp Wii HDMI adapter for a compatible standard Wii. Match the Wii’s output mode to a resolution your TV accepts. Electron Shepherd says the adapter converts the signal rather than creating HD game detail.
The MAYFLASH W016 accepts NTSC 480i and 480p, plus PAL 576i, and does not upscale the picture. Connect it with a standard HDMI Type-A male-to-male cable; no driver installation is required. If your TV rejects interlaced HDMI, use the Wii’s supported 480p mode with a compatible setup.
Use a powered converter for Wii mini or AV cables
A powered composite-to-HDMI converter accepts the yellow, white and red AV cable from either a Wii or Wii mini. Connect yellow to the converter’s CVBS input and white and red to its left and right audio inputs. Connect HDMI from the converter to the TV, supply the converter’s required power and select the connected HDMI input.
On the OREI XD-M901, supply USB power and use its 720P/1080P switch to choose an output your TV supports. This selects the converter’s output resolution, separate from the Wii’s own resolution setting. It does not give the Wii a native HD connection.
For a standard Wii with a Wii component cable, you can use a compatible component-to-HDMI converter. On the PORTTA RHX, connect green to Y, blue to Pb/Cb and the video red plug to Pr/Cr, then connect the separate white and red audio pair to left and right audio. Connect HDMI from the converter to the TV, attach its USB power adapter and select that HDMI input.
PORTTA says the RHX passes the resolution through without scaling, so your TV must accept the selected Wii resolution. Its inputs do not accept the Wii’s yellow, white and red composite cable. This component connection also excludes Wii mini.
You can use a gaming upscaler when you need supported analog inputs and selectable output resolutions. The RetroTINK-5X Pro accepts composite, S-Video, component and RGB SCART; Wii mini must connect through composite. Connect your Wii using a compatible cable and the corresponding input, then connect the processor’s digital video output to the TV. Supply microUSB power from a 5V/2A source, then use its remote to select the connected input and an output resolution your TV supports.
Select the connected input on your smart TV
Press your TV remote’s Input, Source or TV/Video button and select the port carrying the Wii signal. For HDMI, match the port number, such as HDMI 2. On Samsung TVs, an unrecognized adapter may appear under its port number rather than the Wii’s name.
On Samsung Smart TVs with Connected Devices in Smart Hub, open the Home screen, move to the left sidebar and select Connected Devices. Choose the connected HDMI input. If your TV uses a One Connect Box, connect the converter’s HDMI cable to an HDMI IN socket on that box.
On compatible Sony Android TV and Google TV models, press INPUT, then use the arrow buttons to choose the connected AV or HDMI source. On LG’s 2025 AI Magic Remote, hold Home Hub to display external inputs and select the connected port. On LG’s supported 2020 and 2021 remote layouts, press External Input to change sources, or hold it to open Home Dashboard. Check your remote’s model because button behavior varies.
Set up the Sensor Bar and Wii Remote
Connect the Sensor Bar to its socket on the Wii and center it above the TV or at the front edge of the surface below it. Keep its view toward the player unobstructed. Set the console’s Sensor Bar position to Above TV or Below TV to match its placement.
The Sensor Bar enables pointer operation and does not carry the picture. If you can see the Wii Menu but cannot operate it, complete the remote pairing as well as the Sensor Bar setup.
With the Wii powered on, access the remote’s SYNC button beneath its battery cover or through the cover’s access hole. Press and release it, then promptly press and release the console’s red SYNC button while the LEDs blink. Pairing finishes when a player LED remains lit. The console button is behind the front SD-slot cover on a standard Wii and on the side of Wii mini.
Match the resolution and picture shape
On the North American Wii interface, select Wii Button > Wii Settings > Screen > TV Resolution. Choose EDTV or HDTV (480p) for a compatible component-capable connection, or Standard TV (480i) for interlaced output, then select Confirm. Nintendo says Wii mini does not offer 480p, and some games do not support progressive scan.
To correct a stretched picture on Wii or Wii mini, open Wii Button > Wii Settings > Screen > Widescreen Settings. Choose Standard or Widescreen to match the intended display format, then select Confirm. Match the TV’s aspect-ratio control as well. This changes picture shape rather than resolution, and software support can vary.
Fix a missing picture or delayed controls
First, confirm that the selected TV input matches the physical socket carrying the Wii signal. For a powered converter, check its power connection and make sure the Wii cable feeds its analog input while HDMI runs from its output to the TV. Next, compare the converter’s output resolution with the formats your TV accepts.
For a composite connection, check that yellow carries video and white and red carry audio. Match the TV’s input labels and manual rather than relying on socket colors alone. If you use an AV breakout adapter, check that it is compatible with your specific TV model.
If controls feel delayed, select the Wii’s HDMI input before enabling a compatible TV’s gaming setting. On supported 2025 Samsung models covered by Samsung’s Australian instructions, open Settings > All Settings > Advanced Features > Game Mode Settings > Game Mode and enable it. On supported 2023 and 2024 models, open Settings > All Settings > Connection > Game Mode Settings > Game Mode and enable it. Samsung says this reduces display processing delay.
On compatible LG TVs running webOS 22, display the connected HDMI source and open Settings > All Settings > General > Game Optimizer, then select ON. Change Picture Mode to Game Optimizer when needed. Press Settings again to display Game Dashboard.
Frequently Asked Questions
Can you connect a Wii to a smart TV wirelessly?
You can consider wireless HDMI only after converting the Wii’s output to a signal the extender accepts. Connect the converter’s HDMI output to the transmitter, connect the receiver to the TV’s HDMI input, power both wireless units and select that TV input. The J-Tech Digital JTECH-WEX4K-100 accepts relevant HDMI modes, but compatibility with this Wii setup is inferred from its interfaces, and J-Tech does not certify the combination. Added wireless latency can affect gameplay.
Can a phone app display the Wii picture on the TV?
Phone remote apps select the TV’s input; they do not provide native Wii casting, Bluetooth video or Wi-Fi screen mirroring. If your compatible Samsung TV is already added to SmartThings, open its TV device card and select Remote. Use its Home and navigation controls to open the TV’s input selector and choose the connected Wii input.
Can you select the Wii input without the TV remote?
On Samsung TVs with a single-button TV Controller, press the TV Controller once to display its control menu, use short presses to move through it and hold it to select the source control and connected input. Joystick-style controllers use directional movement and a center press. Check your model’s manual for the controller’s location and operation.
Can you add an internal HDMI port to a Wii?
You can have an experienced installer fit the ElectronAVE Kit using Electron Shepherd’s revision-specific soldering instructions; it supports standard Wii revisions and excludes Wii mini. Connect its installed mini-HDMI output to the TV and select that HDMI input. If the installer soldered a connection to one of the Wii’s GameCube controller ports, open the kit’s settings by holding L + R + X + Y for a few seconds on a GameCube controller plugged into that port. To use a compatible universal remote with the installed IR sensor board instead, first hold the IR button on the installed board until the configuration screen appears, then press six buttons on your remote for the highlighted functions, one after the other.
