Inputs and Outputs
Elgato Game Capture HD60 has two inputs, and two outputs:
This connects to a game console or other video source. Signals protected by HDCP can't be used.
Analog Audio In
This connects to an analog audio source, using an 3.5mm cable. This is audio line in, and not a microphone port.
This sends the H.264 encoded video to your computer via USB 2.0. The signal is delayed by a few seconds from live. The USB cable also powers the Elgato Game Capture HD60 hardware.
This sends the HDMI signal in real time to a TV or display, so you can play your game normally.

Troubleshooting - No Image Appears On The TV
If your TV only supports 1080i or 720p, and not 1080p, then you may not get a video image when Elgato Game Capture HD60 is first connected. The video may still appear in the software, but not on your TV.
The solution would be to set your Wii U to output video to 720p or 1080i - whatever format your TV can support.
