Connecting Wii to AT&T U-verse Box (STB) — Not Direct

You **cannot** connect a Wii *to* an AT&T U-verse Set-Top Box (STB). The STB is an **input source** (outputs video to TV), not a display input.

Correct Connections

1. Wii → TV Direct:
   • **Composite (Yellow/Red/White):** Wii AV Cable → TV AV In (Video + L/R Audio). Select "AV" / "Video" / "Composite" on TV remote.
   • **Component (YPbPr — 480p):** Wii Component Cable → TV Component In (Red/Blue/Green Video + Red/White Audio). Enable **480p** in Wii Settings → Screen → TV Resolution → EDTV/HDTV (480p).
   • **HDMI (Requires Adapter):** Wii2HDMI / Pound HDMI / Kaico → TV HDMI. Upscales to 720p/1080p. Low lag.
2. U-verse STB → TV: HDMI (best) or Component / Composite → *Different* TV Input.

Switching Between Them

• Use **TV Remote → Input / Source Button** to toggle: HDMI 1 (U-verse) ↔ AV/Component/HDMI 2 (Wii).
• **Universal Remote (Logitech Harmony / SofaBaton):** One-button activities ("Watch TV", "Play Wii").

If TV Has Only One Input

• HDMI Switch (3×1 or 5×1): $15–$25. Plug Wii (via HDMI adapter) + U-verse + other → One TV HDMI. Button/Remote switches.
• AV Switch (Composite/Component): $10–$20. Manual button.

Audio (Optional)

• Wii Analog Audio (Red/White) → **Soundbar / Receiver / Powered Speakers** if TV speakers bad.
• U-verse HDMI → TV → ARC/eARC → Soundbar (single cable).

No signal flows *into* the U-verse box. Connect both to TV (or switch), select input.
