How do you connect a Wii U to a computer monitor that doesn't have a HDMI port? I have to do that as I don't have a TV, though that will only be temporary. The monitor is an iMac 27 inch, and it has built in speakers. Also, I only need to connect the console to the monitor to set it up, because from a not so quick search, a TV is needed to set up a Wii U. Correct me if that is wrong though.
