53Runco VX-40d/-50d/-60d/-80d Owner’s Operating ManualSection 3: Operation

Use  the 
Configuration   menu  to 
define general operating parameters 
and communications with other 
projectors and equipment, and to 
access other advanced processing 
and image adjustments affecting 
overall performance. In addition, the 
Configuration menu provides access 
to diagnostic and calibration tools, 
as well as the  Ser vice submenu 
(password protected).
Keep in mind that settings in the  Configuration menu (and its submenus) are typically 
“global” settings applied regardless of the type of source your are using. This 
characteristic is identified with the (globe) icon alongside the option.  NOTE: The 
Configuration menu is recommended for experienced users/technicians only.
The first six options in the  Configuration menu are explained below:
Language
Choose from available languages to use in the projector’s menus. The change will take 
effect immediately.
Image Orientation
Set  the  orientation  of  the  image  according  to  the  orientation  of  your  projector.  If  the 
setting is incorrect, projected images will be reversed and/or upside down.
Fade Time
Set  how  long  (in  seconds)  it  takes  to  gradually  dissolve  one  image  into  another  for  a 
source switch.
Auto Power-up
Enter a checkmark to enable the projector to automatically power up after losing power 
due  to  a  power  failure  or  due  to  unplugging  the  projector  during  operation.  Runco 
recommends  that  this  be  left  unchecked,  as  a  power  loss  in  an  unattended  house  will 
result in the projector turning on without anyone realizing it is on.
Note that unsaved display adjustments may be lost.
Set Date and Time
Enter/read the current year-month-day and hour-minute-second. Changes here reset the 
projector’s real-time clock.

Menu Preferences — 
SUBMENU
Use  the  options  in  this  submenu 
to  adjust  the  appearance,  content 
and/or location of on-screen menus 
and messages.
LARGE  MENU  FONT  —  Enter  a 
checkmark  to  enlarge  menus  and 
their text. You may have to adjust “Menu Location” to accommodate the increased menu 
area.
MENU LOCATION — Use the pull-down list to choose a pre-defined default or customized 
location for the display of all on-screen menus. 
To create a custom menu location quickly, choose a preset that is closest to the desired 
location. Then adjust “Horizontal Shift” and “Vertical Shift” slidebars to move the menu to 
the desired location. Avoid locations too close to a corner or edge to prevent cropping of 
larger menus.
HORIZONTAL SHIFT AND VERTICAL SHIFT — Shift your menus as desired, creating 
a customized menu location.
DISPLAY CHANNEL LIST — Enter a checkmark if you want to see a scrollable channel 
list whenever you press Channel (
CHANL) from your presentation. Channels marked with 
a list icon in the  Channel Setup menu will appear here. The “Display Channel List” option 
also enables on-screen feedback when using the Input key. If you prefer to hide the channel 
list and input dialog box while switching channels and sources during a presentation, clear 
the checkbox.
NOTE: The Channel List and input dialog box cannot be hidden during use of the 
menus.
DISPLAY  SLIDEBARS  —  This  setting  is  not  applicable  to  this  projector/remote 
combination.
DISPLAY ERROR MESSAGES — Choose in what way you want to be notified of errors 
detected in either the incoming signal or projector. Select “Screen” or “All” to see a brief 
on-screen message or select “RS232” to receive messages via RS232 (or RS422) serial 
communication  only.  Select  “Off”  to  hide  error  message  displays.  Because  the  DHD 
Controller uses the RS232 port, Runco recommends this be set to Screen
.

Settings  in  the  Communications  submenu  define  and  control  how  single  or  multiple 
projectors are can link with each other and with a controlling device.
Baud Rates
The baud rate setting determines the speed of communication to and from the 
projector on the RS232 or RS422 links. The maximum rate for either standard is 
115200. The default baud rate for use with the DHD Controller is 115200. If this is 
changed, communication with the DHD Controller will be lost.
Projector
Enter a three-digit number (such as “001”) to assign or change a number to the 
projector currently in use. If the current projector already has a number assigned, 
that number will appear here (for example, “004” in Figure 3.14, above). Numerical 
identity for projectors enables you to communicate with a single projector within a 
multiple-projector application. If you make a mistake in assigning or changing the 
projector number, press 
Exit to cancel. 
NOTE: This feature is not used when the projector is used with the DHD Controller .
Network Routing
NOTE: This feature is not applicable when the projector is used by itself, with the DHD 
Controller or in a simple serial network with only one type of controller and linking.
SEPARATE: Select “Separate” (factory default) to keep RS232, RS422 and Ethernet 
messages on their respective paths instead of being broadcast to the other types 
of ports.

Ethernet Settings (SUBMENU)
This menu is reserved for future use.
Backlight
Toggle the built-in keypad lighting on/off.
Front IR / Back IR
As needed for your application, set to “on” so that the front and/or rear IR sensor 
locations on the projector responds to the IR keypad. Set to “off” to disable.
To disable 
both IR sensors, you cannot use the IR remote keypad to select the second 
OFF setting. This safeguard prevents accidentally disabling an IR keypad while you 
are using it. Instead, use either the built-in keypad or a wired remote (optional) to 
set the remaining active sensor to OFF. The projector will no longer respond to an 
IR remote keypad.
Wired Keypad
Select “On” to enable use of a wired remote keypad connected to the rear of the 
projector. The projector will then respond to incoming commands from either port. 
To disable the wired keypad, you must use a different keypad—the built-in or an IR 
remote keypad—to select “off”. This safeguard prevents you from accidentally disabling 
the wired keypad during use.

In the 
Configuration  menu, select 
the Geometry and Color  submenu 
when you need to modify overall 
color performance and/or image 
geometry for all sources.
Test Pattern
Choose the desired internal test pattern or select OFF to turn off a test pattern. 
Alternatively, use the  TESTP key for cycling through test patterns.
Vertical Keystone
Use to correct a keystoned image shape in which both sides of your image are 
inclined toward the top or bottom edge. Keystone is typically caused by tilting the 
projector in relation to the screen, so that the lens surface and screen are no longer 
parallel to each other.

NOTE: Runco recommends that the keystone feature not be used unless absolutely 
necessary, as it may cause some artifacting in the image.
Brightness Uniformity — SUBMENU
Brightness Uniformity  provides further refinement of displays already matched for 
their primary colors and overall light output. Use Brightness Uniformity to create an 
exceptionally smooth image in which no area appears brighter and/or more red, green 
or blue than another. In the  Brightness Uniformity menu, check the “Uniformity Enable” 
checkbox to access a multitude of adjustments for critical color light output control 
in specific areas throughout the image. Your settings apply as long as the “Uniformity 
Enable” checkbox is enabled and you are using a “User” color temperature defined 
by the Brightness Uniformity controls. Remove the checkmark from the “Uniformity 
Enable” checkbox to disable the Brightness Uniformity function.

Edge Blending — SUBMENU
The Edge Blending submenu provides a range of controls for smoothing together 
the overlapping bright edges of multiple adjacent projected images to create a single 
larger “seamless” image.
Color Adjustments by X/Y, and Color Saturation — SUBMENUS
NOTES: 1) For defining or changing a User 1, 2, 3, or 4 color performance or “gamut”. 
Sometimes known as Comprehensive Color Adjustment™. 2) Factory-measured 
primary color levels, which ensure a specific color performance from projector-to-
projector, can be altered in the 
Service menu only. If you suspect alteration of these 
defaults, the factory settings can be recovered with selection of “ 
Factory Defaults” 
in the Color Primary Settings submenu accessed via the Service menu (password-
protected).
From the factory, the projector can utilize any 
of the three pre-defined color performance 
settings identified at right (default=Max 
Drives) or colors can be driven on the basis 
of color temperature. For most applications, 
one of these options will produce accurate 
and realistic colors from a variety of sources. 
They can be applied at any time in the 
Advanced Image Settings  menu (“Select 
Color Adjustment”) and are not adjustable.
DEFINING “USER” COLOR GAMUTS:  In some cases, you may find that none of the 
predefined “Select Color Adjustment” options exactly suit your needs. For example, 
you may require a unique color gamut (range) for a single projector or application, or 
you may need to precisely match colors across multiple adjacent displays. In such 
cases, use either the Color Adjustments by X,Y  or Color Saturation  submenu to define 
the precise hue of each primary color component (red, green, blue, and white) used 
to generate the millions of colors produced in displays. You can create up to four 
custom color gamuts (User 1, 2, 3, or 4) defined by these adjustments.
Note  that  the  two  menus  differ  only  in  their  user  interface,  so  use  whichever  menu  best 
suits your needs and application.
•    Color Adjustments by X,Y —  Enter known x/y coordinates from the chromaticity 
graph. For best results, use with a color meter.
•   Color Saturation —  Adjust color slidebars and judge image color by eye. A color 
meter can also be used.
A user-defined color “adjustment” can be applied by selecting it in the Advanced 
Image Settings menu (“Select Color Adjustment”).
NOTE: Defining a “User” color gamut when a test pattern is displayed does not get 
saved in the current channel. Display the source first, then select a color gamut (User) 
from Select Color Adjustment. Changes here are then saved for that source in channel 
memory. 
						

							
59Runco VX-40d/-50d/-60d/-80d Owner’s Operating ManualSection 3: Operation

COLOR ADJUSTMENT BY X,Y: 
Use this submenu if you want to 
alter, add or copy a color gamut 
(i.e., “color adjustment”). Controls 
in this menu define the precise hue 
of each primary color component 
(red, green, blue, and white) used 
to generate the millions of colors 
produced  in  displays.  The  x/y 
coordinates for each color define 
its location on the standard CIE 
chromaticity  graph  (see  Figure 
3.16)—changing  either  or  both 
of these numbers will change the 
hue of the color, and relocate the 
“triangle” for possible colors. For example, changing the x/y coordinates for red will 
either move the color closer to orange or closer to violet, which will in turn affect all 
displayed colors having a red component. Adjust the slidebars or enter new specific 
coordinates as desired to define or change up to four “User” color gamuts needed 
for your environment and applications. Apply the new “User” color gamuts at any 
time in the 
Advanced Image Settings  menu.
NOTE: Keep new x,y coordinates within the original color gamut triangle shown here. 
Refer to Section 6, Specifications, for color primaries.

Section 3: Operation

COLOR  SATURATION:  Use  this 
submenu if you do not have specific 
color  coordinates  in  mind  and  will 
simply  judge  color  performance 
by  eye  (or  meter).  Like  the 
Color 
Adjustment  by  X,Y  submenu,  each 
color  control  actually  defines  new 
x/y  coordinates  for  that  color  and 
changes its hue — it is just a different 
interface.
Adjust the hue of each primary color 
(red, green, blue, and white) by using 
more  or  less  of  it  in  relation  to  the 
other colors.
NOTE: A Color Saturation adjustment sets the corresponding x/y coordinates shown 
in the Color Adjustment by X,Y submenu. These x/y coordinates will remain stable for 
this User gamut until they are changed again via either menu. Values displayed in the 
Color Saturation menu, however, will likely fluctuate as you use the projector, and will 
be different when you return to this menu at some point in the future. These floating 
changes do not affect the x/y coordinates or gamut.
Test Pattern
Choose the desired inter nal test 
pattern to display or select OFF to 
turn off a test pattern. Alternatively, 
use  the  TESTP  button  on  the 
remote control for cycling through 
test patterns.
NOTE: Runco recommends that all 
calibration parameters (grey scale, 
sizing, etc.) be done with external 
test patterns.
Test Pattern Grey Level
Set the desired level of grey for displaying in the full gray field test pattern.
Freeze Image
Enter a check mark to freeze (stop) an image on a single frame. This diagnostic tool is 
useful if you need to examine in detail a still version of an incoming image that cannot 
be “frozen” at the source. For example, in moving images it is sometimes difficult to 
observe artifacts such as external deinterlacing/resizing and signal noise. Remove 
the checkmark to return back to normal.

Color Enable
Select  which  color  or  colors  you  want  to  see.  This  is  useful  while  working  with  color 
temperature, input levels or other special setup parameters. 
Odd Pixel Adjustment 
NOTES: Factory-set and rarely required by user. 
When using certain RGB sources, you may need to adjust the normal gain or offset 
of odd pixels in relation to even pixels. This will smooth out very narrow (1-pixel wide) 
“checks” or vertical stripes that indicate adjacent “on” and “of f” pixels. Although offset 
and gain slidebars can be adjusted individually and manually, using the Level Detector 
simplifies this process (see Figure 3.21):
  1.  Use  an  external  analog  native-sized  continuous  grayscale  test  pattern  with  at 
least 256-levels.
  2. Turn “Level Detector” on.
  3.  Set “Level Value” to 
~200. The image should now be black-and-white (or black-
and-one color, if you use “Color Enable” function).
  4. Adjust 
offset. Half of the pixels will move, the other half will not.
  5.  Adjust until the two transition regions overlap. The stripe of noise will be minimized,  defined by the value in the slidebar.
  6.  Set “Level Value” to 
~800. The image should now be black-and-white.
  7.  Repeat Steps 4 and 5, but adjusting 
gain.
  8.  Repeat  Steps  3-7  for  all  remaining  colors.  Your  RGB  source  should  now  be 
OK.
NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 
represents no change in normal odd pixel offset or gain. 3) Odd Pixel Adjustment 
eliminates “1 pixel on, 1 pixel off” patterns only, not any type of larger patterns.

No function.
Peak Detector
The “Peak Detector” is fast method of defining individual input levels, and can improve 
the accuracy of input levels set by the Auto Input Level function. Enabling the “Peak 
Detector” activates a special operating mode for detecting 
only pixels that are 
considered black or white — all other levels are displayed as a mid-level gray. When 
used with a 16-step grayscale pattern in which the two black and white bands are 
known to be at opposite edges of the image, you can watch these isolated areas 
while adjusting individual blacklevels and input drives until both bands are just visible. 
Images from this source will then display correct blacks and whites without crushing 
or washing out.
Level Detector
The “Level Detector” checkbox enables specific thresholds for blacks and whites — input 
levels that fall below a specified  Level Value (see below) are displayed as black, and 
all others are displayed as white. It aids in Odd Pixel Adjustment. To use:
  1. Enable “Level Detector” and display a continuous grayscale.
  2. Set “ Level Value” to near black (such as 200).
  3. Adjust Offsets to minimize area of black stripe.
  4. Set “ Level Value” to near white (such as 800).
  5. Adjust Gains to minimize area of white stripe.
Level Value
The “ Level Value ” defines the value to be used by the  Level Detector in recognizing 
blacks and whites. Refer to  Level Detector, above.
Whenever  you  install  a  new  lamp  in  the
