8. Input menu
Genlock off (default position) locking done on input source of main window, when automatic was selected or on the
selected input source when a speci
fi c input was selected. Projector detects automatically the vertical
frequency and clock frequency of the input signal. A slightly difference with the source is possible.
Genlock on locking done on indicated vertical frequency and clock frequency. This vertical frequency and clock frequency
must be exactly the same as those of the source.
Only use genlock ON for very stable sources and preferable for broadcast sources.
For Genlock on,
to change the locking frequency, use the ▲ or ▼ key to select Vert freq and press ENTER to activate. The fi rst digit is selected.
Use the ▲ or ▼ key to select the desired digit and press ◄ or ► key to select the next digit in the address or enter the value with
the digit keys on the remote control or local keypad. The next digit in the value will be automatically selected.
to change the clock frequency, use the ▲ or ▼ key to select Clock freq and press ENTER to activate. The fi rst digit is selected.
Use the ▲ or ▼ key to select the desired digit and press ◄ or ► key to select the next digit in the address or enter the value with
the digit keys on the remote control or local keypad. The next digit in the value will be automatically selected.
For older custom fi les, created with software packages older than package 1.5.6, the Genlock function will
be grayed out. If you want to use this genlock function, a new custom fi le must be created starting from the
standard fi le. Copying the custom fi le in a new fi le do not solve this issue.
8.4 Minimum delay
Purpose
In normal mode, the processing (scaling and de-interlacing) in DLP projectors introduces a few frames delay (from input to screen).
Setting the option
Minimum Delay to "ON" disables all scaling and de-interlacing in the processing and reduces frame delay of the
projector (from input to screen) to ONE frame, caused by the formatter board (DLP technology restriction). The intended use of this
option is to apply native and progressive data to the projector and displaying it with minimum delay, using the full resolution of the
projector. Other formats will be displayed either unscaled and/or interlaced.
This feature can be used if additional delay in the projector is not acceptable. For instance if a projector is showing the DVI loop out
of another DLP or if an external scaler/de-interlacer does the processing.
How to toggle the delay?
1. Press MENU to activate the menus.
2. Use the ▲ or ▼ key to select Input and press ENTER .
The Input menu is displayed.
3. Use the ▲ or ▼ key to select Minimum delay and press ENTER to toggle between [On] and [Off].

8.5 Native resolution
What can be done
The aim here is to always show the resolution of the source independently of the resolution of the DMD panels.
