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.
Press the "Menu" button on the Vizio's remote to open the menu screen.
Press the arrow key to bring up the Wide menu. Press the down arrow to the "Wide" option and press "OK" to change the Vizio's picture settings to display 1,080-pixel signal with the best possible picture.
