DCT5100 User Guide
The DVI/YPbPr OUTPUT setting displays as YPbPr OUTPUT if you are
not using the DVI video connection. The user settings will also be
displayed on the front panel LED whether your TV is off or on.
If the on-screen display menu does not appear on your HDTV screen,
your TV may not support the default video output setting. Use the
DCT5100 front panel LED to view and change your settings.
