A method ( 100; 200 ) and apparatus ( 230 ) for controlling a display of video being output from a set-top box determines ( 102 ) if a user selected channel contains programming having a first aspect ratio and stretches ( 106 ) automatically video from the user selected channel having the first aspect ratio, if the user selected channel contains programming having the first aspect ratio, to fill a frame having a second aspect ratio that is different than the first aspect ratio using a predetermined stretching function. This determining and stretching is initiated automatically upon tuning ( 101 ) to a user-selected channel. According to another aspect of the present invention, an exemplary embodiment ( 200 ) of a method for controlling video output from a set-top box, upon receiving a zoom toggle command from a user via a remote control unit, the method determines ( 202 ) if a user-selected program includes a second aspect ratio different than a first aspect ratio and ignores ( 205 ) the zoom toggle command if the programming does not include the second aspect ratio. If the programming does include the second aspect ratio, then the method selects ( 206; 208 ) a next available zoom mode for a first or second aspect ratio television type if the television type setting is set for the first or second aspect ratio, respectively, and sets ( 207; 210 ) an output format to a mode specified by a first predetermined output setting.
