Change the viewing settings of your Vizio HDTV to the 1080 setting to enjoy TV shows and videos in the best possible resolution. The 1080 format requires a wider viewing format that isn't supported by every type of input. However if you're using an HDMI cable to connect to your cable box, Blu-ray player or other video source then you will want to set your TV to the 1080 setting for the clearest picture.
Turn on the Vizio TV.
