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. 
These controls, which primarily affect white levels, are typically used in conjunction with mechanical 
lens blinders (optional), which are installed on the front of the projector and which primarily affect 
black levels. There is a centerline (both horizontal and vertical) in the Edge Blending test pattern. 
The intersection of these lines is the true center of the projector’s display area.

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-defined  primary  color  levels,  which 
ensure a specific color performance from projector-to-projector, can be calibrated in the Service 
menu only. If you suspect alteration of these defaults, the factory settings can be recovered with 
selection  of  “Reset  to  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  gamuts  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	 pre-
defined	 “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 the  Color Adjustments by X,Y 
or Color Temp Adjust	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) with these \
adjustments.
Note that the two menus differ only in their user interface, so use whichever menu best suits your 
needs and application. A color meter can help with adjustments.
Color Adjustments by X,Y
•   — Enter known x/y coordinates from the chromaticity graph.
Color  Temperature Adjustment
•    — Adjust  color  slide  bars  and  judge  image  color  by  eye  or 
meter.
A 	user-defined	 color	“adjustment”	 can	be	applied	 by	selecting	 it	in	 the	 Advanced Image Settings 
menu (“Select Color Adjustment”).
Section	3	►	Operation
ColoR  aDjUsTMenT  bY x,Y: Use this submenu if you want to create, alter 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  3.17)—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  may  move  the  color  closer  to  orange  or  closer  to  violet,  which  will  in  turn  affect  all 
displayed	 colors	having	 a	red	 component.	 Adjust	the	slide	 bars	or	enter	 new	specific	 coordinates	
as	 desired	 to	define	 or	change	 up	to	four	 “User”	 color	gamuts	 needed	 for	your	 environment	 and	
applications. Apply at any time in the Advanced Image Settings  menu.

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 Temp Adjust 
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.

Black  Edge  Blending   is  a  feature  that  eliminates  the  differences  between  black  levels  when 
edge  blending  multiple  projectors. The  Black  Edge  Blending  submenu  provides  many  controls 
to allow the edges of adjacent images to be smoothly overlapped creating a “seamless” image. 
Edge blending smoothes white levels, and if edge blending is not in use, Black Edge Blending 
is  disabled.  Black  Edge  Blending  provides  a  simple  solution  for  uneven  black  levels,  without 
the  need  for  external  hardware,  by  matching  up  black  level  hues  with  a  “target  area”  hue  (the 
intersection of the center lines), and adjusting the overlaps (edges) surrounding the target area. 
noTes:  1)  There  is  a  centerline  (both  horizontal  and  vertical)  in  the  Black  Edge  Blending  test 
pattern. The intersection of these lines is the true center of the projector’s display area.  2) Adjust 
white levels before adjusting black levels. 3) Blinders are recommended for fixed installations.

lens VaRIsCoPe™ (l Vs™) — sUbMenU
LVS™	 provides	 the	ability	 to	recall	 focus	and	zoom	 settings	 specific	to	each	 source	 input.	Custom	
lens  settings  you’ve  chosen  for  any  source  will  be  quickly  and  accurately  applied  when  you 
select a source that has already been calibrated. Place a checkmark in the checkbox to enable 
LVS™. If no calibration has previously been done you may be prompted to do a full calibration. 
If a motion calibration has been done, you will be prompted to complete a reference calibration. 
If both calibrations have been done, the checkbox will be checked and LVS™ enabled. If LVS™ 
is  enabled,  a  reference  calibration  will  be  done  on  power  up  and  the  lens  will  return  to  the 
saved position of the source that is active at the time of power up or to the position the lens was 
located  when  it  was  powered  on.  Further  adjustments  to  the  zoom,  focus  and  position  will  be 
automatically saved for source the selected source. If you switch to a source with different lens 
settings  and  switch  back,  the  lens  will  automatically  move  to  your  saved  settings  upon  return. 
Other sources can be used without using LVS™ .
noTes: 1) See  System Configuration – Diagnostics/Calibration, LVS Calibration  for further 
details about calibration.  2) LVS™ control is a preference setting and will be retained between

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  de-interlacing/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. Colors can also be enabled/disabled by entering 
the corresponding function code listed on the back of the standard remot\

noTes: 1) Factory-set and rarely required by user. 2) Source must be >90 MHz.
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  (one-pixel  wide)  “checks”  or 
vertical	 stripes	that	indicate	 adjacent	 “on”	and	“off”	 pixels.	 Using	the	Level	 Detector	 simplifies	 this	
process (see Figure 3.18):
Use  an  external  analog  native-sized  continuous  grayscale  test  pattern  with  at  least 
1. 
256-levels.
Turn “Level Detector” on.
2. 
Set  “Level  Value”  to 
3.  ~200.  The  image  should  now  be  black-and-white  (or  black-and-one 
color, if you use “Color Enable” function).
Adjust 
4.  offset. Half of the pixels will move, the other half will not.
Adjust	 until	the	two	 transition	 regions	overlap.	 The	stripe	 of	noise 	will	 be	minimized,	 defined	
5. 
by the value in the slide bar.
Set “Level Value” to 
6.  ~800. The image should now be black-and-white.
Repeat Steps 4 and 5, but adjusting 
7.  gain.
Repeat Steps 3-7 for all remaining colors. Your RGB source should now be OK.
8. 
Two sets of values are automatically saved with these controls — one value for Input #1, and one 
for Input #2 (analog). The current set of values depends on which source is in use. This enables 
a source to be processed correctly via two different inputs.

PeaK DeTeCT oR
The	 “Peak	 Detector”	 is	a	fast	 method	 for	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 black levels and white levels until both 
bands are just visible. Images from this source will then display correct blacks and whites without 
crushing or washing out.
noTe: If using Peak Detector with PIP, both images must have the same color space.
leVel DeTeCT oR
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:
Enable “Level Detector” and display a continuous grayscale.
1. 
Set “Level Value” to near black (such as 200).
2.

lens VaRIsCoPe sYsTeM (lVs™) CalIbRaTIon
This option allows you to choose between three types of lens calibrations.  Reference calibration 
determines	 a	reference	 point	that	is	used	 as	a	defined	 starting	position	 for	relative	 motion	of	the	
lens. All  positioning  is  measured  from  this  reference  point. A  reference  calibration  is  lost  when 
power  is  removed  from  the  projector  and  will  occur  on  every  power  up  as  long  as  LVS™  is 
enabled. A  Motion calibration determines the characteristics of each motor and values are saved 
in  the  projector’s  memory.  If  LVS™  is  enabled  and  a  motion  calibration  has  previously  been 
done, the projector will automatically recall these settings from memory when it’s being powered 
up and a motion calibration will not take place. A  full calibration performs both a reference and 
motion calibration.
 
aUT oMa TIC l Vs lens CalIbRa TIon
When this option is selected (default) and the projector is in LVS mode, the projector will perform 
a lens calibration on each power-up. During calibration, the shutter will be closed and the status 
LED will display ‘LC’. If LVS is not selected, the ALC setting will be ignored. If, during power-up, 
ALC is not selected and LVS is, the last stored location from the previous LVS calibration will be 
assumed to be true and the lens will moved to that position upon power-u\
p if necessary.
noTe: It is recommended to leave this feature disabled.
The two “Option Card” entries In the  Display Setup menu identify which optional input modules 
(a.k.a.  cards)  are  present  at  InPUT  5  (Option  1)  and InPUT  6  (Option  2).  If  either  of  these 
option slots is empty, the corresponding read-only menu entry does nothing. If there is a module 
installed, the corresponding menu entry may activate a submenu of further options pertaining to 
that module.
For  example,  if  the  Dual  SD/HD-SDI  module  is  installed  at  InPUT  5  (Option  1).  The  Option 
1	 Card	 submenu 	provides	 controls	for	configuring	 the	various	 connections	 on	this	 multi-input,	
multi-output	 module.	As	desired	 for	your	 application,	 you	can	define	 1)  which  physical  input 
loops through to which output, and  2) which functional input (main or PIP signal) loops through 
to which output.
Select Automatic mode or a series of manual modes. In Automatic mode the input video payload 
information  is  read  and  compared  to  that  of  the  SMPTE  352  standard  to  detect  the  dual  link 
format  and  the  primary  channel.  Single  video  input  will  also  work  in  this  mode  without  any 
payload information. Dual link input video which does not contain payload information must be 
set up manually. Select the format and which of the two channels is the primary input.

Section	3	►	Operation
PIP (Picture-in-Picture) and Seamless Switching are independent but related projector features 
that  both  utilize  two  image-processing  paths  within  the  projector.  In  the  case  of  Picture-in-
Picture,  this  double  processing  enables  you  to  display  two  different  images  simultaneously  – 
typically a smaller “secondary” image within a large “primary” background.  In a seamless switch, 
the  double  processing  essentially  occurs  between  displays  so  that  a  full  image  relayed  from 
one source can smoothly transform into a full image from another source. This change can be 
virtually  instantaneous,  or  slowed  as  desired  so  that  the  current  image  appears  to  dissolve  or 
“fade” into the new image.
Options for enabling and controlling PIP and Seamless Switching all reside in the same menu. 
Note,  however,  that  because  both  features  utilize  the  projector’s  double  processing  capability, 
PIP and Seamless Switching cannot be used together. For example, fading a pair of PIP images 
into a new display from a different source is not possible.
For best PIP or Seamless Switching results, use two different	signal	types*	 as	defined	 below.	Do	
not mix two signals of the same type.
signal Type Description (Input location)
#1 5 BNCs (RGBHV or YPbPr)
#2 DVI - I (analog or digital)
#3 Decoded signals (Input 3, Input 4, Composite video, S-Video, or any video 
signal via Input 1 BNC connectors or via an analog option card).
#4 Analog Option Cards
#5 Digital Option Cards
#6 Digital Option Cards
* HD interlaced sources are not recommended for the PIP window.
Other PIP or Seamless Switching tips to keep in mind include: 	 When	 using	two	digital	 signals	 or	one	 analog	 and	one	digital,	 each	must	be	≤	165	
•	
megapixels. 
When	using	two	analog	signals,	each	must	be	≤	90	megapixels.
•	
Avoid using an interlaced source in the PIP window
•	
Seamless switching may affect image quality in some cases
•	
noTe:  To  control  the  primary  image,  access  all  picture  controls  through  the  Main  menu.  To 
control  the  secondary  (PIP)  image,  access  picture  controls  through  the  Picture-in-Picture  or 
Switching menu.

“Default”  aspect  ratio  when  incoming  format  has  square  pixels  (most  common).  This  ensures 
that  the  resulting  PIP  image  maintains  its  intended  aspect  ratio.  Use  “Anamorphic”  for  NTSC 
signals  having  narrower  pixels--this  will  stretch  the  pixels  horizontally  to  regain  the  intended

noTe:  If the image is already resized at the source it will remain that way in the PIP window. If, 
for example, an NTSC signal is already set to anamorphic through the Resize and Preset menu 
it will remain that way in the PIP window. If the NTSC signal is formatted as widescreen at the
