Solution
There are three ways to display video that is down-converted from the 16:9 aspect ratio used for HD video to the 4:3 aspect ratio used for SD video. You can select one of the following display types in [SD Output] from the [Video Setup] menu.
Squeeze | The image is squeezed from the left and right so that the entire image fits within the screen. The image will appear normal if the external monitor also has a 16:9 aspect ratio. | |
Letterbox | The 16:9 aspect ratio is maintained but black letterbox bars are added to the top and bottom of the image. | |
Side Crop | The left and right sides of the image are cropped so that the central part of the image fits within the screen. |
