It depends on the audio/video connection you are using. If you are using the composite video/audio cables. Which are the Yellow, Red & White cords. Then you are only going to get a definition of 720p. To get the full 1080p resolution & get the best quality out of your Wii U & your TV . You need to use a HDMI cable. Connect an HDMI cable from your WII U to your TV & it will bump up the quality to 1080p.
