My television has a 16:9 widescreen format; if the program is broadcast in 4:3 format, some picture content is cut off at the top and bottom?
The set-top box and flat screen TV may be set to automatic format adjustment. As a result of this, the picture size of a program broadcast in 4:3 format displayed on a 16:9 flat screen may be enlarged (zoom) until the width of the picture is the same size as the 16:9 screen. As the enlargement (zoom) doesn’t alter the picture proportions, the height of the picture increases accordingly and the picture content at the top and bottom of the picture is lost.
If you would like to change your picture format you need to change your viewing mode in the navigation menu on your flat screen TV.
Unfortunately, there is no standardization for flat screen menu navigation. Please refer to the user’s manual for detailed menu navigation.
