    Whenever you install a new lamp in the projector, 
    access  the Lamp  menu  to  record  the  lamp  serial 
    number  in  the  projector’s  memory.  You  can  also 
    choose a lamp mode for regulating power and light 
    output,  change  Iris  size,  and  access  other  read-
    only  information  pertaining  to  past  and  present 
    lamps.
    laMP  hoURs  (read-only)  shows  the  number 
    of  hours  logged  on  the  current  lamp.  Whenever 
    you  record  a  new  lamp  serial  number  this  value 
    automatically  resets  to  “0”,  where  it  begins  to 
    log  time  for  the  new  lamp.  This  information  also 
    appears in the  Information menu. 
    laMP  s/n (read-only) is the serial number recorded for the current lamp. When you install a new 
    lamp and enter its serial number, the number will appear here. 
    Enter  a  checkmark  for  LAMP  MESSAGE  to  enable  a  warning  message  that  will  appear  upon 
    power-up	 when	the	lamp	 has	reached	 the	specified	 lamp	limit	and	should	 be	replaced.	 Delete	
    the checkmark to prevent display of this message — instead, when your lamp expires, only the 
    status display messages on the back of the projector will provide the visual warning to replace 
    the lamp.
    noTes:  1)  It  is  recommended  that  the  Lamp  Message  checkbox  remain  enabled.  2)  When  a 
    lamp warning message appears, press 
    Exit to temporarily cancel the message. The message 
    will continue to appear upon power-up until you install a new lamp.
    Set  laMP  lIMIT to the number of hours you expect to log on the current lamp before replacing 
    it. This will trigger a lamp message on-screen (if enabled).
    noTes:  1)  If  you  change  modes  over  the  life  of  a  lamp,  the  lamp  limit  you  originally  expected 
    may no longer be possible.  2) Turning the lamp on and off reduces lamp life significantly, as do 
    other factors.  3) It is recommended that Lamp Limit not exceed the expected lamp life, otherwise 
    a lamp could become dangerously fragile with overuse.
    Set  which  laMP  MoDe  you  want  to  use  in  order  to  control  the  light 
    output.  You  can  choose  to  run  the  lamp  as  bright  as  possible  (i.e., 
    always  using  maximum  power  —  this  is  the  default  upon  power  up) 
    or	 you	 can	power	 the	lamp	 with	a	specific	 wattage	 appropriate	 for	the	
    installed	 lamp	or	you	 can	set	a	specific	 intensity	 (brightness)	 to	maintain.	 Although	there	are	
    exceptions, generally higher light output or higher power settings can s\
    horten lamp life.
    Use the lamp mode that best suits your brightness needs. For example, in a tiled application you 
    may  want  to  precisely  match  brightness  levels  between  adjacent  images  —  judge  by  eye  and 
    set each individual  lamp Power setting as necessary. Or if you want images to be as bright as 
    possible — choose  Max brightness. Always keep in mind that higher lamp power settings can 
    shorten lamp life.

    							3-49
    Lamp modes are described below:Max  brightness:
    •   The lamp will always burn as brightly as possible, driven by 100% of the 
    power  level  rating  for  the  installed  lamp  (see  Section  6,  Specifications).  Keep  in  mind 
    that  the  “maximum  brightness”  for  any  lamp  gradually  diminishes  with  age  —  images  will 
    become dimmer over time. Its current output level appears in the “Intensity” option (not in 
    lumens).
    Intensity:
    •  	Brightness	 will	remain 	close	 to	a	specified	 level	for	as	long	 as	possible.	 Once	
    you  select  this  option,  enter  a  number  representing  the  intensity  level  (brightness)  you 
    wish to maintain — the projector will automatically adjust power as needed to maintain this 
    intensity as closely as possible. Note that the intensity value is a correlation only and does 
    not represent an actual lumens level. See “ Intensity” below.
    Power: 
    •  The	power	 supplied	 to	the	 lamp	 will	remain	 at	your	 specified	 wattage	level.	Once	
    you  select this option,  enter the number  of watts representing  the power  level  you wish  to 
    maintain. See “ Power” below.
    PoWeR  –  This  slidebar  and  number  indicates  how  many 
    watts are applied to the lamp. You can apply anywhere from 
    approximately 60-65% of the maximum power intended for the installed lamp up to 100% of the 
    lamp  rating.  Set  for  the  number  of  watts  as  desired,  keeping  in  mind  that  lower  power  levels 
    produce  dimmer  images.  When  in  either  Power  or Max brightness  modes,  the  power  level 
    remains  constant.  Specifying  a  maximum  power  level  here  is  the  same  as  operating  in  Max 
    brightness mode.
    noTe: Power level can be set only if the lamp is in  Power mode.
    InTensITY – This value and slidebar represents the current 
    brightness of your lamp, decreasing over time when you are 
    operating  in  Max brightness	 mode	or	at	a	specific	 Power  level.  When  you  are  operating  in 
    “Intensity”  mode  this  value  remains  at  the  original  “Intensity”  setting  chosen  and  cannot  be 
    adjusted.
    noTe:  The number shown for “intensity” is not the actual lumen output, but rather a correlated 
    value only — 1246 may represent 3500 lumens, for example.
    To  use  “Intensity”  mode,  judge  by  eye  (or  use  a  meter)  and  set  the  level  as  desired  for  your 
    application. Over time, the projector will automatically increase the power supplied to the lamp 
    as needed to maintain the chosen intensity as closely as possible.
    hoW  long Can I MaInT aIn bRIghTness? Software can maintain your “Intensity” setting 
    until  the  required  power  reaches  the  maximum  rating  for  the  lamp.  The  lower  the  setting,  the 
    longer it will take to reach this threshold and the longer you can maintain the desired brightness. 
    Keep in mind that once the lamp power reaches its maximum wattage (see “Power”, above), this 
    tracking is no longer possible. At this point, the lamp will gradually begin to dim as usual, even 
    though your original “Intensity” value will still appear in the menu. To resume accurate tracking, 
    reduce the intensity setting so that the resulting “Power” value is less than its maximum — the 
    lower the intensity, the longer it can be maintained.
    Section	3	►	Operation 
    						
    							3-50
    For example, a 1000 watt lamp can be driven at no more than 1000 watts. To produce desired 
    brightness at the screen, a new lamp would likely need less than this maximum rating — perhaps 
    812 watts (example only). Over time, however, the lamp will require more and more current in order 
    to generate the desired light, until eventually the lamp wattage reaches its 1000-watt maximum 
    and the lamp power automatically levels off. At this point, the tracking function terminates (i.e., 
    the power level stabilizes) and the lamp will begin to dim normally. Either reduce your “Intensity” 
    setting or replace the lamp.
    Do not lower the “Intensity” so much that the corresponding “Power” value reaches its  minimum 
    — the intensity setting will be inaccurate and cannot be maintained. For best results in achieving 
    uniform  intensity  amongst  tiled  images,  choose  an  “Intensity”  setting  that  enables  all  lamps  to 
    operate at less than the maximum number of watts available in your projector but high enough to 
    keep the corresponding lamp power above its minimum. See “ Power”, above.
    noTes:  1)  Lamps  become  more  stable  over  time,  thus  a  specific  intensity  is  more  easily 
    maintained  as  the  lamp  ages.  2)  Intensity  can  be  set  only  if  the  lamp  is  in  “Intensity”  mode  3) 
    Intensity cannot exceed the output of Max Brightness mode.
    IRIs  –  The  IRIS  inside  the  projector  controls  the  diameter  of  the 
    light beam passing through the system. With a fully open aperture 
    (slidebar  default  of  “0”),  the  maximum  amount  of  light  passes 
    through  for  maximum  brightness  in  your  images.  Increase  the 
    slidebar  setting  to  reduce  the  aperture  diameter  and  maximize 
    contrast ratio instead.
    laMP  hIsToRY – This read-only option lists the lamps most recently installed 
    and  recorded  in  the  projector.  Lamp  History  automatically  updates  whenever 
    you record a new lamp serial number — the new lamp is added to the bottom 
    of the list.
    Use Change laMP to record the serial number for a newly installed lamp:
    In the  Lamp S/N window, use the number text entry keys to record the new lamp serial number 
    and press again to accept the change. See  Using Slidebars and Other Controls if you need help 
    entering  the  number.  Once  entered,  the  new  lamp  serial  number  will  be 
    added  to  the  Lamp 
    History menu 
    and the  Lamp Hours timer will reset to “0”.  Lamp Mode and Lamp Limit remain as 
    they were for the previous lamp and can be changed at any time. See Figu\
    re 3.19.

    noTe: Enter  a  serial  number  only  if  you  have  just  installed  a  new  lamp.  This  will  help  ensure 
    that lamp timer is not reset on an old lamp and that the number of hours logged on the lamp will 
    be accurate.
    IMPoRT anT: Always record the serial number of a NEW lamp.
    When  a  new  lamp  is  installed  and  its  serial 
    number recorded by selecting “Change Lamp” 
    in  the  Lamp  menu,  the  lamp  timer  resets  to 
    “0” and begins logging time for the new lamp. 
    This tally appears in both the  Lamp menu (see 
    right) and the Information menu.
    To  review  the  number  of  hours  logged  for 
    previous  lamps,  consult  the  Lamp  History 
    menu.
    If  the  “Lamp  Message”  checkbox  has  been 
    enabled  in  the  Lamp  menu  (recommended), 
    an expiry message will appear upon power-up 
    when	 the	lamp	 has	reached	 its	defined	 “Lamp	
    Limit”. The lamp should be replaced.
    The  “Lamp  Limit”  setting  should  not  exceed  the  expected  lamp  life,  as  an  old  lamp  becomes 
    increasingly fragile and more prone to sudden failure. 
    The  read-only  Information  menu  lists  a  variety  of  details  about  the  standard  and  optional 
    components  currently  detected  in  the  projector.  Refer  to  the  Information  menu  for  versions  of 
    hardware  and  software  installed,  the  type  (size)  of  lamp,  the  hours  logged  in  total  and  for  a 
    specific	 period	(such	as	a	rental	 period),	 and	for	your	 projector	 model	name	and	serial	 number.	
    In addition, the  Information	menu	identifies	 the	current	 channel,	 its	location,	 its	frequencies	 and

      Before You Begin
    Read through the entire procedure before attempting to adjust White Field Uniformity controls, 
    and keep in mind the following checklist of prerequisites and guidelines\
    : 
      aDjUsT ColoRs  fIRsT — Always adjust the primary colors as described in the “Matching 
    Colors  in  Multiple  Screens”  procedure  (above)  before  attempting  to  work  with  White  Field 
    Uniformity. This ensures that primary colors, color temperature, and maximized light output 
    are all well matched from one screen to another. These matches are needed before you can 
    achieve good White Field Uniformity results.
      RUn  laMP  foR 100  hoURs —	Light	 output	 and	White	 Field	Uniformity	 can	vary	 significantly	
    during	 the	first	 100	 hours	 of	lamp	 use.	For	best	 results	 with	new	 lamps,	 either	set	up	White	
    Field Uniformity after this period, or do an initial setup and re-check \
    at 100 hours
      seT  laMP  PoWeR  —  Ensure  that  each  “Lamp  Power”  setting  is  as  high  as  possible  for 
    your  application  while  still  maintaining  a  good  overall  match  of  light  output  from  screen-
    to-screen.  By  nature,  achieving  a  uniform  brightness  will  require  a  slightly  reduced  overall 
    brightness—this reduction will help ensure that you have enough range of adjustment when 
    examining  brightness  variables  more  closely  from  screen-to-screen,  and  will  help  prevent 
    premature “maxing out” when trying to match to a certain color, zone or projector.
      Use  a  “UseR”  ColoR  TeMPeRa TURe  —  Always  adjust  White  Field  Uniformity  for  a 
    User	 color	 temperature	 defined	when	you	matched	 primary	colors,	and	continue	 to	use	 it	
    for all sources displayed on the wall. Your other color temperatures will not necessarily be 
    matched from screen-to-screen.
      WhITe UnIfoRMITY  slIDe baRs — White Uniformity slide bar values may not reduce to 
    “0”.	 Each	 slide	bar	adjusts	 overall	light	output	 in	a	specific	 screen	zone,	but	the	value	 shown	
    represents  the  current  setting  for  green  in  this  zone.  When  other  “hidden”  values  (red  or 
    blue) are lower than green, during adjustment in the White Uniformity menu their values will 
    reach	“0”	first,	causing	the	slide	
    bar	
    
    to	stop	earlier	than	expected.
      jUDge  bY eYe  oR Use  a MeTeR — Good White Field Uniformity can be achieved with 
    either.

    sTeP 1: geneRal seTUP
    1a)  Adjust primary colors (see Matching Colors in Multiple Screens) to ensure matched overall 
    color temperatures and light output between screens.
     IMPORTANT 
    Double-check that all WHITES and LIGHT OUTPUT are well-matched.
    1b)  Enable the White Field Uniformity checkbox. 
    This  will  enable  access  to  the  uniformity 
    controls  and  will  apply  the  settings  to  your 
    image.
    1c)  Select the 13-Point test pattern for display. This pattern 
    provides nine screen “zones” with 13 targets.
    foR  besT ResUl Ts: Rather than examining the CENTER 
    of  each  zone  when  assessing  White  Field  Uniformity 
    adjustments  focus  on  extreme  EDGES  as  indicated  in  the 
    illustration at right.
    1d)  In either Color Adjustments menu, select a “User” color. Then:
    If you have created a “User 1” color gamut (recommended) for a well-matched wall, continue 
    •	
    to Step 1e.
    If  you  prefer  maximum  brightness  rather  than  a  particular  color  temperature,  select  “Max 
    •	
    Drives”.
    IMPoRT anT: Do not change User 1 Color Adjustment in color-matched applications!
    1e)  In the  White Uniformity menu, set the “Overall” output level to  50.0 and all remaining slide 
    bars to  0.0. This decreases the light output just enough throughout the screen so that any 
    color level can then be increased later 
    as necessary for matching light output 
    from zone-to-zone. Do not exceed  50.0 
    for  “Overall”—a  higher  level  will  likely 
    interfere  with  achieving  White  Field 
    Uniformity and is not recommended.
      Ensure  that  overall  light  output 
    remains well matched from one screen 
    center  to  the  next.  Where  necessary, 
    increase  or  decrease  Lamp  Power 
    slightly to recover center matches.

    noTes:  1)  At  this  point,  ignore  the  brightness  of  individual  zones.  2)  Always  ignore  menu 
    colors.
    2a)  On each screen, compare the color temperatures in the eight target zones (four edges and 
    four corners) to that of the color temperature of the center. Compare using a  white	field	only,	
    and take note of any areas that do not match the center. Also decide if any screen exhibits 
    a more obvious color shift than other screens — begin with this scree\
    n in Step  2b. 
    2b)  Return to the  White Field Uniformity menu. Beginning with the screen that exhibits the most 
    obvious  color  shift(s),  for  each  edge  that  exhibits  a  noticeably  different  color  temperature 
    from the center, select the corresponding  Uniformity adjustment menu — Left, Right, Top or 
    Bottom. For example, if any part of the left side is too blue, too red or too green, go to the 
    Left Uniformity menu and adjust the colors (i.e., change their light output) until all portions of 
    the	 left	side	 closely	 match	the	center	 color	temperature.	 Adjust	an	edge	 first	(focusing	 on	its	
    center), and then adjust its corners. See Figure 3.21.
    Repeat the color adjustment of sides and corners for each edge of the screen that does not yet 
    match the center (note that each corner is adjustable in either of its two adjacent “side” menus). 
    When done, all areas of a given screen should match. Repeat Steps  2a & 2b for all remaining 
    screens.
    sTeP  3: aDjUsT lIghT oUTPUT In eIghT zones
    3a)  For each screen, compare the light output of each  edge and  corner to that of the  center. If 
    any  of  the  areas  differ,  use  the  White  Uniformity  menu  to  match  edges  and  corners  to  the 
    center  as  described  below  (see  Figure  3.22).  Begin  with  the  screen  exhibiting  the  most 
    obvious variations in light output.
    Adjust 
    •	 edge White Uniformity	 first—note	that	each	 edge	 adjustment	 also	affects	 the	rest	 of	
    the screen slightly. Keep all edges just slightly lower than the center light output rather than 
    matching  light  output  precisely.  Otherwise,  it  may  not  be  possible  to  brighten  the  corners 
    (typically the dimmest areas of the screen) enough. I.e., the best uniformity is a compromise 
    between the brightest and darkest areas of the screen.
    Adjust 
    •	 corner White Uniformity last—each corner adjustment affects only this quadrant. 
    Repeat for each screen.

    If you do not want to use or apply White Field Uniformity settings, delete the checkmark from the 
    “Uniformity Enable” checkbox at the top of the  White Field Uniformity menu.
    Edge Blending  is an innovative set of software functions that can quickly and easily blend white 
    levels along the edges of multiple adjacent projected images to create a single seamless larger 
    image.
    Wha T Is a blenD?
    In simple terms, a blend appears as a gradient strip along an 
    edge  of  a  projected  image.  It  is  darkest  along  the  extreme 
    edge  of  the  image,  and  lightens  nearer  to  the  rest  of  the 
    image (see right).
    hoW  aRe blenDs UseD?
    In  multiple-projector  walls,  complementary  blends  between 
    neighboring images can compensate for the extra “brightness” 
    or intensity where these edges overlap. By controlling blend 
    width and other properties, you can achieve uniformity across 
    the  group  of  images.  Visible 
    overlaps will disappear:
    Figure 3.23. Edge Blending Concept
    3.10  edge blending 
    						
    							3-56
    Section	3	►	Operation
    For best results, use the same projector model and type throughout your display wall. In addition, 
    avoid high-gain screens whenever possible—the optical performance of such screens demands 
    minimal image offset, thus projectors must be located very close to one another.
    Edge blending software controls are located in the two-page Edge Blending submenu—access 
    via  Display  Setup  menu,  then  go  to  the  Geometry  and  Color  menu  and  select Edge  Blending. 
    The More option opens the second page of the  Edge Blending submenu.
    MaIn fUnCTIons
    Use  Edge  Blending  controls  to  set  the  precise  width, shape  and midpoint   you  need  to  blend 
    overlapping edges together smoothly. blend Width
    •   determines  how  much  area  is used for blending  along  an overlapping  edge. 
    Slide bar values represent the number of eight-pixel steps used for the blend. For example, 
    a	 setting	 of	“eight”	 creates	 a	blended	 edge	24	pixels	 wide.	A	setting	 of	“0”	 signifies	 no	
    blending. For best results in most applications, use a blend width of 16-48 steps (128-384 
    pixels).
      Ranges: 0-80 horizontal, 0-60 vertical.
      blend  shape
    •    determines  the  rate  of  roll-off 
    across  the  blend  width,  i.e.  how  quickly  the 
    white  levels  across  the  blend  change  from 
    light  and  dark.  Increasing  the  Blend  Shape 
    setting accelerates the rate of change at both 
    extremes so that less of the region appears 
    mid-gray  (see  Figure  3.24).  Decreasing  the 
    Blend Shape setting slows the rate of change 
    so that more of the region appears mid-gray. 
    For  most  applications,  this  subtle  control  is 
    best left close to 50. 
     
    blend  Midpoint
    •    determines  the  white  level 
    at  the  blend  midpoint  (the  point  equidistant 
    between the beginning and end of the blend). 
    Increasing the  Blend Midpoint  setting creates 
    a blend that appears brighter than the rest of 
    the  image.  Decreasing  the  Blend  Midpoint 
    setting  creates  a  blend  that  is  darker  than 
    the rest of the image. A setting of 50 means 
    the  midpoint  is  approximately  50%  black—
    for  best  results  in  most  applications,  keep 
    fairly close to this default.
