ServiceUse the Service menu to access advanced projector configuration settings. This menu 
should be used by ISF-certified technicians only.
Test Video: Select Test Video from the Service Menu to access the internal test patterns 
on the VX-2. Four patterns are available, consisting of white/gray or colored bars. 
Press MENU to exit test pattern mode.  
 
 
 
 
Input Names: You can give each DHD Controller input a descriptive name. For example, 
you may want to change the default input name to the type of source component 
connected to it: “VCR,” “DVD,” “Laptop” et cetera. Composite, S-Video and Component 
SD input names can be up to 12 characters long; the others can be up to eight characters 
long. 
To edit an input name, select Input Names from the Service menu. Press  or  to select 
an input and press ENTER. Use the  or  buttons to change a character; press  or 
 to select a character to change. When you have finished editing the input name, press 
MENU. 
To restore the default input name, press  repeatedly to highlight that input name in the 
“Restore” column. Then, press ENTER. 
To save input names so that they can be restored after a System Reset (described on 
page 51), press  repeatedly to highlight “Save.” Then, press ENTER. 
Remote Control: The Remote Control menu shows you the primary and secondary 
infrared (IR) codes to which the VX-2 will respond. By default, both are set to 17. You can 
change these codes if either:
 Another device in the theater (a DVD player, for example) is responding to commands 
from the VX-2 remote control in ways that are unpredictable or undesirable. 
 You have multiple VX-2 projectors and want to control them independently, as 
opposed to broadcasting commands from a single remote to all of them. In this 
scenario, you can use multiple remotes programmed to use different IR codes. Or, you 
can use a single remote and change the IR code as needed to address a specific 
projector.

When you change a remote code on the VX-2, you must re-program your remote control 
to send that same code. To do this:
1. Using a straightened paper clip or similar object, press and hold the 
CODE button on the remote control for approximately three 
seconds, or until the red LED on the remote lights solid red.
2. Enter a new two-digit code between 00 and 31 inclusive. Include a 
leading zero for single-digit codes; for example, enter 9 as “09.”
3. The LED turns off to confirm the code change. If you enter an invalid code, the LED 
flashes for three or four seconds. Try again, entering a valid code. 
Display Device: The options in the Display Device menu allow you to change the picture 
orientation, reset the lamp timer, perform lens adjustments and access additional test 
patterns.
 Installation: Select Installation from the Display Device menu to change the picture 
orientation to suit the method of installation (Floor Front, Floor Rear, Ceiling Front or 
Ceiling Rear). 
This menu page also displays the number of hours that the lamp has been in service, 
and lets you reset the counter (which is recommended after you replace the lamp; refer 
to 
Lamp Replacement on page 53).
Lens: Select Lens from the Display Device menu to access the motorized lens 
controls. Refer to 
Lens Adjustments on page 36. 
 Diagnostics: Select Diagnostics from the Service menu to access additional test 
patterns for calibration or measurement purposes:
Select Red, Green or Blue to display only the selected color (simulating a filter of 
that color). 
Select 75 or 100 to display color bars (75 IRE or 100 IRE). 
Select Horz or Ver t to display a horizontal or vertical gray ramp. 
Select Checks to display a 15-segment checkerboard pattern. 
Select Align to display a white grid against a black background (useful for verifying 
proper image or screen alignment). 
HD Format: If the characteristics of the incoming signal on the HD1 or HD2 inputs are 
known, select HD Format from the Service menu and set them as described below. Doing 
so can reduce the time it takes the DHD Controller to switch from HD to 480i signals or 
vice versa. 
This is generally not necessary unless the DHD Controller – for whatever reason – has 
difficulty determining the color space (RGB or YUV), bandwidth or resolution of the 
incoming HD signal. In most situations, the Auto settings work well. 
 HD/RGB 1 and HD/RGB 2 (Color Space): Select Auto, RGB or YUV.
 ADC Bandwidth: Select Auto, 75 MHz, 150 MHz or 300 MHz.
 YPbPr Input Resolution: Select Auto or specify the input resolution, if known: 480i, 
480p, 576i, 576p, 720p or 1080i. 
Do not change the “Type” setting in this menu. Note

Triggers: Select Triggers from the Service menu to configure the 12-volt trigger outputs. 
You can assign one or more trigger outputs to each aspect ratio. Those triggers are then 
activated by selecting that aspect ratio. 
If your projector is equipped with the Runco CineWide with AutoScope system, assign at 
least one trigger output (the same one to which the lens motor is connected) to the 
Cinema and Virtualwide 2.35 aspect ratios.
To save the trigger settings so that they can be restored after a System Reset (described 
below), press 
 repeatedly to highlight “Save.” Then, press ENTER. 
Miscellaneous: Select Miscellaneous from the Service menu to set the following options: 
 Language: Select Language from the Miscellaneous menu and press the up- or 
down-arrows to select the OSD Language (English, French, Spanish or German).
 Menu Mode: This is the manner in which the OSD menus appear and disappear when 
you press MENU. Choose one of the following: 
0 = No transition; menus abruptly appear and disappear.  
1 = Menus fade in and out.  
2 = “Checkerboard” dissolve; menus appear and disappear in sections.  
3 = “Window shade” effect; menus are drawn on a diagonal from top left to bottom 
right, and retract in the opposite direction. 
 Timeout - Short/Long: These settings control how long the OSD menus stay on 
screen. Select a time-out period of from 2 to 60 seconds. 
 Side Bar Color: This controls the color of the inactive image area. The range is from 
-100 (black) to 100 (white). 
 
 
The inactive image area is on either side of the active image area when using the 
Standard 4:3 aspect ratio, and above and below the active image area when using the 
Letterbox aspect ratio. 
 Film Mode: Enable Film Mode to smooth out moving images from interlaced, 
standard-definition (SD) sources. In most cases, the VX-2 detects the proper 
“pull-down” rate and vertical frequency. However, if your source is jittery and/or tearing 
you may wish to enable Film Mode to ensure stable processing for that source. 
Resolution: The DHD Controller defaults to an output resolution of 720p. When using the 
VX-2 with a computer or certain HD sources, you may want to force the DHD Controller to 
use a different output resolution. If so, select Resolution from the Service menu and 
choose one. Then, press ENTER to confirm. 
System Reset: To reset ALL projector and controller settings (including image settings) 
back to their factory defaults, choose System Reset from the Service menu. 
A confirmation message appears, reminding you to save your settings before you perform 
the reset, so that you can restore them afterwards. If you have done this, select Confirm to 
continue with the reset. Otherwise, click Back to cancel. 
 
Restore Saved Settings: Following a System Reset, select Restore Saved Settings to 
apply all previously-saved settings to the projector and DHD Controller.
This action is not undoable. Proceed with caution! Before you 
perform a System Reset, save ALL settings, including “Custom” ISF 
Presets (
page 46), ISF Day/Night presets (page 48), Output Shift 
settings (page 48), Input Names (page 49) and Trigger settings (see 
above).
