The default for all DIP switches is Off (down).
DIP switches — This bank of DIP switches is used to configure the interface. The
switches control:
1.
DDSP or ADSP — DDSP disables all sync processing. This feature may be necessary
for digital display devices such as LCD, DLP (digital light processor), and plasma
displays. Use this option if the image is not displayed properly after other options,
such as serration pulse and video termination changes, have been tried.
On — The interface uses DDSP instead of ADSP. DDSP does not process the sync
signal.
Off — The interface performs sync processing operations, such as centering, with
ADSP.
NOTE:
DDSP disables the horizontal and vertical centering controls.
2.
Sync On Green (SOG)
On — The interface outputs a composite sync signal on top of the green video
signal (SOG) via the G output connector (RGsB).
Off — The interface outputs separate horizontal and vertical sync (on the H and V
connectors) and composite sync (on the S connector) for RGBHV or RGBS.
3.
Serration pulses
Many LCD and DLP projectors and plasma displays do not display properly if
serration pulses are present in the sync signal. Flagging or bending at the top of the
video image is a sign that the serration pulses should be removed.
On — The interface outputs serration pulses in the vertical sync interval.
Off — The interface does not output serration pulses.
4.
Vertical sync pulse width
For some digital displays, if:
no picture appears
z
the picture cuts in and out
z
the picture is scrambled
z
try adjusting the output vertical sync pulse width or switching from ADSP to DDSP.
On — The vertical sync pulse is narrow.
Off — The vertical sync pulse is wide.
