16:9 – A wide-screen aspect ratio for video.
15:9 – Uses the full display.
Letterbox – Reduce image to display the true aspect with black borders on top and bottom.
True – Displays the current image in its true resolution.

Overscan
Video images normally exceed the size of the display screen. The edge of the picture may or may not be displayed cor-
rectly. The border area that is cropped can be adjusted by using the Overscan menu.
Set the overscan percentage between 0 – 15% to compensate for different screen sizes.
WXGA Mode
Selecting On gives priority to a WXGA (1280 x 768) signal when recognizing an input signal.
When WXGA Mode is set to On, an XGA (1024 x 768) signal may not be recognized. Set WXGA Mode to Off if this occurs.
To check if the signal is recognized, go to "Input" under "Information" menu (see page 90).
