How to Adjust Vizio Aspect Ratios
The aspect ratio on your TV dictates how the image appears on your screen. Some people leave their TV on one aspect ratio regardless of what they are viewing, while other people prefer one aspect ratio for movies, another for sports and so on. Vizio TVs give you a variety of aspect ratio options: full screen, stretched screen and two zoom levels. You can change the aspect ratio on your Vizio TV using the remote control that came with your TV.
Turn on your Vizio TV.
Press the "Menu" button on the Vizio remote.
Highlight "Setup" using the arrow keys on the remote, then press the "Play/Pause" button.
Highlight "Wide" using the arrow keys on the remote. Press the left and right arrow buttons on the remote to switch between different aspect ratios.
Press the "Exit" button on the remote to save your changes after you have found the aspect ratio you like.
