CalibrationUse the Calibration menu to perform advanced picture quality adjustments. This menu 
should be used by ISF-certified technicians only. 
To recall the ISF Night or ISF Day settings, select “ISF Night” or “ISF Day” from the ISF 
Presets menu (see above). 
ISF Night - Display Color: Use the Display Color settings to change the characteristics 
of the output signal. These settings are global (independent of any particular input). 
Gain: Use the Gain controls to correct color imbalances in the bright areas of the 
image. A good way to do this is to use a test pattern consisting mostly of solid white 
areas, such as an 80 IRE “window” pattern. If the white areas contain traces of red, 
green or blue, decrease the Gain for that color.
Offset: Use the Offset controls in the White Balance sub-menu to correct color 
imbalances in the dark areas of the image. A good way to do this is to use a test 
pattern consisting mostly of dark gray areas, such as a 30 IRE “window” pattern. If the 
gray areas contain traces of red, green or blue, decrease the Offset for that color.
 Gamma: “Gamma” is a global setting that determines how gray shades are displayed 
between minimum input (black) and maximum input (white) for all signals. A good 
gamma setting helps to optimize blacks and whites while ensuring smooth transitions 
for the “in-between” values utilized in other grays. Unlike “Brightness” and “Contrast” 
controls, the overall tone of your images can be lightened or darkened without 
changing the extremes and all images will be more vibrant while still showing good 
detail in dark areas. 
In all but the most unusual situations, the appropriate “Color Temp” selection (see 
below) will produce accurate colors and a satisfying contrast level. However, it is 
sometimes necessary to adjust the red, blue and green gamma curves individually. To 
do this, select Gamma from the Display Color sub-menu and use the left- and 
right-arrow buttons to manipulate the on-screen slidebars. 
 Iris: Select Iris from the Display Color Menu to increase or decrease the Reflectance 
Volume Regulation setting. RVR lets you control the aperture or iris size (the physical 
opening through the lens; similar to an “f-stop” on a camera). Doing so allows you to 
optimize brightness and contrast according to the amount of ambient light in the 
viewing area. 
Use the lower setting (1) for rooms with lots of ambient light. Use the higher setting (2) 
for more “theater-like” viewing conditions (little or no ambient light). 
 Color Temp: Select Color Temp from the Display Color menu to adjust the color 
temperature. The default setting is appropriate for most situations. Higher settings 
produce a “bluer” picture.
ISF Night - Input Image: The Input Image controls are similar to those in the Picture 
menu, but are accessible only by entering the Calibration menu passcode. This makes it 
possible to restore the picture quality settings to what they were when the projector was 
installed, simply by recalling the “ISF Night” preset.

ISF Night - Input Color: The Input Color controls are similar to those in the Display Color 
menu (see above), but can be set independently for each input. 
 Gain/Offset: Refer to ISF Night - Display Color, above. 
 Chroma Delay: use the Chroma Delay control to correct a mis-aligned image from a 
Composite, S-Video or Component video source. Chroma delay in an image causes 
color shifts to occur to the left of the vertical edge transitions, producing artificial 
shadows or a “halo” effect. If necessary, adjust this setting to eliminate them. 
Phase: Adjust the phase if the image (usually from an RGB source) shows shimmer or 
“noise.” Pixel phase adjusts the phase of the pixel sampling clock relative to the 
incoming signal. The effect of this control is similar to that of a tracking control on a 
VCR. 
For best results, use a good test pattern such as a smooth gray consisting of a clear 
pattern of black and white pixels, or a similar “half on, half off” graphic image. (You may 
notice that you can stabilize the image at more than one point. Use either setting in this 
case.) 
 Noise Filter: Select Noise Filter from the Input Color menu to filter a noisy Composite, 
S-Video or Composite source signal. Adjust as desired, keeping in mind that reducing 
noise (which reduces high frequencies) may also soften the image. 
ISF Day - Display Color: Refer to ISF Night - Display Color. 
ISF Day - Input Image: Refer to ISF Night - Input Image. 
ISF Day - Input Color: Refer to ISF Night - Input Color. 
Save ISF Settings: Whenever you make a change to the ISF settings, you should always 
save it. Select Save ISF Settings from the ISF Calibration menu to do this. In the event you 
ever have to perform a 
System Reset, you can restore the saved ISF settings by selecting 
Restore Saved Settings in the Service menu. (System Reset and Restore Saved Settings 
are described on page 54.)
Output Shift: The controls in the Output Shift menu are similar to those in the Input 
Position menu, except that they change the characteristics of the output signal (so the 
change is visible no matter which input is selected). You can set these controls 
independently for each aspect ratio. 
To save the Output Shift settings for the current aspect ratio so that they can be restored 
after a System Reset (described on 
page 54), press  repeatedly to highlight “Save.” 
Then, press ENTER. 
Splash Configure: Use the Splash Configure menu to customize the appearance of the 
start-up message that appears on the vacuum fluorescent display upon power-up. You 
can have the VX-4000d/VX-5000d display the owner’s name, your name, the phrase “ISF 
Calibrated” and/or any other string, up to 20 characters in length. 
Use the up or down cursor button to select a character. Use the right and left cursor 
buttons to change the cursor position. Press MENU when you have finished entering text. 
Then, check the “Splash Enable” box to have the VX-4000d/VX-5000d display the 
information you enter here when it is turned on. 
OSD Position: Select OSD Position, press ENTER and use the arrow buttons to change 
the size and position of the OSD controls.

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 54), 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-4000d/VX-5000d 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 standard DHD remote control (
Figure 2-6) in ways that are unpredictable or 
undesirable.
 You have multiple VX-4000d/VX-5000d 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-4000d/VX-5000d, you must re-program the 
standard DHD 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. 
Analog Out Mode: Select Analog Out Mode from the Service menu to change the 
characteristics of the analog output signal from the DHD Controller. The choices are 
RGB-- (separate sync with negative polarity), RGB++ (separate sync with positive polarity) 
or RGBS (composite sync). 
Display Device: The options in the Display Device menu allow you to select the projector 
input source, change the picture orientation, perform keystone correction and reset the 
lamp timer.
 Configure: Select Configure from the Display Device menu to access the following 
projector-specific functions.
Input Source: Press  or  to select the projector input source (1 for RGBHV or 
2 for DVI).  
Orientation: Change the picture orientation to suit the method of installation (Floor 
Front, Floor Rear, Ceiling Front or Ceiling Rear). 
Keystone: If the projector and screen are not installed perpendicular to each other, 
the image may become distorted in a trapezoidal shape, as shown in 
Figure 4-7. 
Select Keystone from the Configure menu to compensate for this. 
Figure 4-7. Keystone Correction
Use the DHD Controller front-panel keypad to change the projector 
IR code. Then, change the code sent by the remote to match as 
described below. 
If the DVI 1 or DVI 2 input is active and the input signal is 
HDCP-encrypted, the RGBHV output of the DHD Controller is 
disabled.

Lamp Hours: 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 55). 
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. 
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 (or the entire screen when no incoming video signal is 
present). 
 Film Mode: Enable Film Mode to smooth out moving images from interlaced, 
standard-definition (SD) sources. In most cases, the VX-4000d/VX-5000d 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-4000d/VX-5000d 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 48), ISF Day/Night presets (page 50), Output Shift 
settings (page 50), Input Names (page 51) and Trigger settings 
(page 53).
