use anything other than hdmi and i will hate you with a passion unless you dont have a hdmi tv witch will make you a monster

i use nintendo to output video on my tv, any other questions?

i use HDMI

I use HDMI but I got this Wii U second-handed and they used AV but I switched it

Bro who's out here using a composite cable for their Wii U, you must still have one of those CTR TV's :skull:

Believe it or not, the Wii U will allow outputting 1080P through the component connection. It's good that they thought ahead that far, but unless you really want to use up those jacks in your TV, it's probably a good idea to use HDMI anyway.
