An RCA widescreen television can display images in both widescreen 16:9 and standard 4:3 formats. The two widescreen modes allow you to select whether or not you want to display the image with overscan. Overscan crops a small area around the edges of the picture and zooms the rest of the image to fit the entire screen. The standard 4:3 mode shows the image with black bars on the left and right sides, but does not distort the picture. There are also options to make 4:3 images fill the screen by cropping top and bottom or stretching the image.
Press the "ASPECT" button to toggle through the TV's aspect ratios.
