Main Menu
The main menu lists the input channel select item, 6 sub menus, and a menu item for automatic setup
of VGA modes. The 6 sub menus are Output, Color, Geometry, Multiple Unit, Enhancement and
System.
On each menu page an Exit menu item is available to leave the menu or submenu. VP-794 also has a
separate back key to leave a submenu.
Some adjustments are not applicable to all signal types or operating modes, in which case those non-
applicable functions will be greyed out and are not accessible.
All menus have a top status line and a bottom line indicating the firmware revision number.
In the status line the currently selected input channel is indicated and the detected mode is identified.
The bottom line shows the firmware revision number of the boot-loader behind BL and the revision
number of the firmware behind FW.
Navigating the menu system or changing values is done with the jog wheel.
To set up your VP-794 it is recommended that you follow this procedure:
Choose the correct output mode and parameters to suit your projector or videowall.
For a LED videowall set window size to match the LED videowall module to be driven using the built in
test patterns, the white box around the outside of the ‘Aspect Test’ pattern is particularly useful for this
purpose.
Select the correct input signal.
Set the input levels and features appropriately to optimize the appearance of your image.
Set any other parameters to suit your application.
Note: The processor is designed to have separate memories for all the settings in each section. All Input
parameters are specific to your chosen input channel and input signal type, unless specified, they are
not global to the unit. If you change the settings in, for example, the composite video channel you will
not affect the settings you may have made in for example the DVI channel.
All Output parameters only affect the output, they do not affect any of the inputs but note that the
appearance on the videowall because it is the output these adjustments will appear to be global.

Input
The list of available inputs can be scrolled through using the jog wheel. The new input is not selected
until the Menu key is pressed. The list of inputs are: CVBS 1, CVBS 2, S-Video, Component, VGA, 3G-
SDI, DVI, HDMI and Test Pattern.
Test patterns can be generated by VP-794 without needing an input connected.
When Test Pattern is selected as the input and menu is off, the required test pattern can be chosen by
the jog wheel.

Output
This menu contains adjustments associated with setting up outputs from the unit. The items are
organized in four sub menus, Display Type, Gamma/Color/Crush, Output Config and Output Window
Size. Use the jog wheel to scroll to the required item and press the Menu key.

Display Type
Settings: LCD/Plasma, Projector & LED
The Display Type setting defaults to Projector.
In LED mode the Windows Size menu is available which allows easy to use adjustment to fit in a given
LED module.
Note: be sure to select Projector if you drive a projector and need the warp and blend functions.
