6.6.2 A/V Settings
6.6.2.1 Screen Format
This setting affects the video format at the VCR / CVBS output.
If your display is 4:3 format and the transmission of a program
happens to be 16:9, the
Letterbox
mode will give you a complete
picture, but black areas will appear at the top and bottom.
Alternatively you can choose the
Center Cut
mode to play the
program in a full-screen format, however information on the left and
right sides may be cut off.
If your display is 16:9 format, then set the mode at
Wide Screen
.
If a program happens to be in 4:3, black areas will appear at the left
and right of the screen in order to present the picture in a correct
aspect ratio.
6.6.2.2 Display Type:
This menu contains two options: Plasma / LCD and CRT. Normally,
different display equipment may have different delay in picture,
which may cause slight problem in lip sync. This feature allows you
to use “Left/Right” to select your choice according to your actual
video display equipment.

There are four default audio modes: Stereo / Left / Right / Mono.
Choose the one you prefer, normally it should be Stereo.

display equipment, in order to compensate for this delay. The delay time depends on which choice appears
to provide best performance of lip sync on your display device.
