I connected an HDMI cable (good quality cable included with the adapter) to the TV, then the cable to the converter and finally the converter to the Wii. And bingo, bango, bongo - now my games are full screen on my Samsung 40" Smart TV. No, these aren't 4K games, but the game fills the entire screen, looks great, and scales well. Nothing will stretched or distorted; The video looks very clear. Oh, it only uses one HDMI cable. The adapter only transmits video and audio to my TV via one HDMI cable. No additional audio cable is required. If you still have a Wii and are using RCA or component cables, buy this adapter and improve your Wii gaming experience by at least 100%.
