I recently got a Wii U. It outputs HDMI too all my TV's except for one. I don't understand why. The TV is a 2006 Panasonic and supports 1080i. Is the TV too old? Any idea how to fix? I know I'm not connecting it up wrong as I repair electronics as a side job. My guess is maybe does the wii u only support 1080p? I don't have a gamepad yet so I can't change video settings.
