Stretch: Stretches squarish 4:3 images across the screen to display the entire image with less distortion than Stan- dard.

Stretch Plus: Similar to Stretch, but minimizes distor- tion on the sides by expanding the picture to crop off

portions of the top and bottom. Use to adjust the vertical position of the picture.

Narrow: Displays narrow 4:3 images in their original shape. Adds black side bars to fill the screen.

Wide Expand: Enlarges the picture, cropping the image on both sides. Removes or reduces black side bars added to narrow images converted to 16:9 signals for digital broadcast.

Note: All high-definition channels send widescreen (16:9) signals, but not all programming was created for the widescreen format. The broadcaster may stretch the image or add side bars to fill the widescreen area.

Full Native: Displays all pixels in the original image
