OSD Menu Notes:
Note 1: The Output sub-menu provides user-selection of the desired output resolution.
Please be aware that some output resolution settings can cause an apparent malfunction if
the selected resolution is not compatible with the connected display device.
CAUTION: Make certain your display device can reproduce the resolution you select
BEFORE you select it.
Note 2: The OSD sub-menu provides user-selection of the On-Screen Display location
and appearance to suit personal preference. You can change the default settings if you
wish, or simply leave it at the factory setting.
Note 3: Since Video and Audio Lip-Sync can be lost in digital television systems, this unit
provides a secondary menu item called “Delay” under the Audio high level menu selection.
An audio delay can be introduced to restore proper lip-sync. Use this function if you hear
audio before the video portion of the program appears to make the corresponding sound.
Note 4: The Info sub-menu contains technical information. If you have problems with this
unit and require assistance, a technician may ask you to read information from this menu
as part of the troubleshooting process.
