NTo set the
switches, use a Tweeker or small screwdriver to slide the switch to the on/up/closed or off/down/open position.
The default for all DIP switches is Off (down).
1 — DDSP
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.
Up — The interface uses DDSP instead of ADSP. DDSP does not process the sync signal.
NDDSP disables the horizontal and vertical centering controls.
Down — The interface performs sync processing operations, such as centering, with ADSP.
2 — Sync on green
Up — The interface outputs a composite sync signal on top of the green video signal (SOG) via the G output connector (RGsB).
Down — 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 will 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.
