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.
Select "Wide" mode for widescreen images with overscan.
Choose "Normal" mode for standard 4:3 images.
Pick "Zoom" to fill the screen with a 4:3 image by cropping the top and bottom.
Select "Cinema" to fill the screen with a 4:3 image by stretching the sides of the picture.
Enable "Dot-to-Dot" to display widescreen images without overscan.
Choose "Auto" to allow the TV to select the aspect ratio based on the input source.
