Hook your wii U up to a non-HD TV...

By using the Wii's video cables.

Is this breaking news, or am I just a dumbass?

Why is this breaking news? And why would you be a dumbass?

I always thought it could only hook up to a flatscreen because it only came with an hdmi cord, so it's breaking news to me really

But why would you connect anything HD to a SD tv these days? You can get a monitor or smaller hdtv with an HDMI port for less than $150!
