Step-by-step guide to connect a Wii to an HDMI upscaler using the RetroTINK HD15 Dongle Wii, including component cable choice, sync handling, and audio routing.
Quick answer
Connect the Wii's component cable to the RetroTINK HD15 Dongle Wii, then plug the dongle into your upscaler's HD15/VGA-style input using a VGA-style cable. Set the Wii to 480p and route audio from the dongle's 3.5 mm jack to your upscaler or speakers. This passthrough adapter keeps YPbPr separate on red, green, and blue lines, so your upscaler must accept YPbPr over HD15.
Check your upscaler accepts YPbPr over HD15
The RetroTINK HD15 Dongle Wii is a passthrough adapter, not a converter. It sends the Wii's YPbPr component signal straight to the red, green, and blue lines of an HD15 connector, so the device on the other end must be able to read YPbPr on those pins. Many VGA inputs expect RGBHV with separate sync, which is a different signal format.
Before you buy cables or start unplugging anything, confirm your upscaler's HD15 port supports component (YPbPr) input. If it only supports RGBHV, this dongle will not convert the signal for you. The dongle's job is clean passthrough with double-shielded cables, not format conversion.
Use the right Wii component cable and set 480p
You need a Wii component video cable (the one with red, green, and blue video RCA plugs plus white and red audio). Plug the video RCAs into the dongle's matching inputs. The dongle passes YPbPr directly, so cable quality matters: use a shielded component cable to avoid interference on the red, green, and blue lines.
In the Wii menu, go to Settings, then Display, and set the output to 480p. If your Wii is set to 480i, many upscalers will still process it, but you lose the progressive-scan benefit. The dongle does not change resolution; it only passes the signal, so the Wii must be set correctly at the source.
Connect the dongle to the upscaler and handle audio
Plug the dongle into your upscaler's HD15 port. If your upscaler uses a VGA-style HD15 input, you may need a short HD15 male-to-male cable or a VGA-style cable to reach the port. The dongle itself is a compact adapter, so plan for cable reach and strain relief.
For audio, the dongle provides stereo output on a 3.5 mm jack with separate shielding. Connect that jack to your upscaler's audio input or to a separate speaker system. If your upscaler only takes audio over HDMI, you will need a separate audio path; the dongle does not embed audio into the video signal.
Test sync, then add a Retro GEM or BlueRetro for convenience
Power on the Wii and check for a stable image. If you see rolling, tearing, or no sync, your upscaler may not accept YPbPr over HD15, or the Wii may still be in 480i. Try a different HD15 cable and confirm the Wii's display setting again.
Once the wired setup works, you can add a PixelFX Retro GEM for digital HDMI output on supported consoles, or an N64 BlueRetro Controller Receiver with Memory Pak to go wireless on Nintendo 64. These are separate upgrades, not required for the dongle to work, but they reduce cable clutter if you run multiple retro systems.
Setup steps
- Confirm HD15 input type: Check your upscaler's manual or menu to see if its HD15 port accepts YPbPr component. If it only accepts RGBHV, this dongle will not work without an additional converter. Checkpoint: the port must say component or YPbPr, not just VGA.
- Connect Wii component cable to dongle: Plug the Wii's red, green, and blue video RCAs into the dongle's matching inputs. Keep the cable short if possible and avoid running it alongside power cables. Mistake to avoid: plugging composite (yellow) into the green input, which gives a black-and-white or unstable image.
- Set Wii to 480p: In the Wii settings, open Display and choose 480p. If your Wii is set to 480i, many upscalers will still show an image but without progressive scan. Checkpoint: the Wii menu should show 480p as the active resolution.
- Connect dongle to upscaler HD15 port: Plug the dongle directly into the upscaler or use a short HD15 male-to-male cable if the port is recessed. Do not force the connector; HD15 is keyed. Mistake to avoid: using a VGA cable that lacks the needed pins for component sync.
- Route audio from the 3.5 mm jack: Connect the dongle's 3.5 mm stereo jack to your upscaler's audio input or to separate speakers. The dongle does not embed audio into the video signal. Checkpoint: you should hear game audio separately from the video path.
- Power on and check sync: Turn on the Wii and look for a stable image. If the picture rolls or drops, recheck the Wii's 480p setting and try a different HD15 cable. Next step: if sync still fails, your upscaler likely does not accept YPbPr over HD15.
Product facts
- RetroTINK HD15 Dongle Wii: Passthru of YPbPr signals directly from the Wii to the Red, Green and Blue lines on the HD15 connector; double shielded cables with individual shielding per signal plus global shield; stereo audio on 3.5 mm jack with separate shielding; durable overmolded design. It preserves the Wii's component signal without conversion, so your upscaler must accept YPbPr over HD15. The shielding helps keep video and audio clean over longer runs.
- PixelFX Retro GEM - Universal HDMI Upscaler: PixelFX Retro GEM is a digital lag-free HDMI output kit for retro consoles with simple WiFi firmware updates and advanced scaling and filters in Shiny Edition. Current console support includes Nintendo 64, Sony PlayStation, PlayStation 2, and Sega Dreamcast. If you want HDMI directly from those consoles instead of routing through an upscaler, the Retro GEM is a different path. It is not a Wii solution, so keep it for supported systems.
- N64 BlueRetro Controller Receiver with Memory Pak (Watermelon Red): N64 BlueRetro Controller Receiver with Memory Pak allows Bluetooth controllers such as PS4, PS5, Xbox, Nintendo Switch, and RetroFighters Brawler 64 BT (incompatible with some controllers) on Nintendo 64. It solves wireless controller pairing for N64, not Wii video. Use it if you want fewer cables on a different console in the same setup.
