Most widescreen television sets bury the aspect ratio adjustment inside a menu, but Polaroid television sets allow the user to change the aspect ratio with a single button press. Users can select between the standard 4:3 aspect ratio, widescreen, stretched images and a zoom mode that fills the screen at the expense of cutting off the image on the sides. Not all models offer every mode.
Locate the "Zoom" or "Aspect" button on the remote.
Press the button to cycle to the next aspect ratio. Press the button repeatedly to cycle through the available aspect ratios.
Stop pressing the button when you get to the aspect ratio you want to use. The TV will remain on this setting until you change it.
