You can select the monitor type to match your TV when you play

DVDs recorded in the picture’s height/width ratio of 16:9.

•16:9 NORMAL (Wide television conversion)

Select this when the aspect ratio of your TV is fixed to 16:9 (wide TV).

The system automatically adjusts the screen width of the output signal correctly when playing back a picture whose aspect ratio is 4:3.

•16:9 AUTO (Wide television conversion)

Select this when the aspect ratio of your TV is 16:9 (wide TV).

Select this when the aspect ratio of your TV is 4:3 (conventional TV). While viewing a wide screen picture, the black bars appear on the top and the bottom of the screen.

•4:3 PS (Pan Scan conversion)

Select this when the aspect ratio of your TV is 4:3 (conventional TV). While viewing a wide screen picture, the black bars do not appear, however, the left and right edges of the pictures will not be shown on the screen.

Ex.: 16:9 Ex.: 4:3 LB Ex.: 4:3 PS

NOTE

•Even if “4:3 PS” is selected, the screen size may become “4:3 LB” with some DVDs. This depends on how DVDs are recorded.

•When you select “16:9 NORMAL” for a picture whose aspect ratio is 4:3, the picture slightly changes due to the process for converting the picture width.
