How to adjust multiple screens
With the Edge blending and Color matching functions, you can seamlessly display the images from more than two 
projectors. Follow the steps below to adjust multiple projector images. 
Confirm if you use the same type of color wheel (high brightness or rich color reproduction color wheel) for each 
projector, and set the same screen size and image level.1
4Adjust the position, focus and zoom of each image if necessary, and then overlap the shaded areas by using the lens 
shift function. When the shaded areas are overlapped with each other correctly, the red lines turn yellow.
Edge blending 
Display the images to be edge blended on a screen. 
(The following example shows the case when you use two projectors (Projector A and B).)
Select ‘Edge blending’ in the setting menu and display the Edge blending dialog box on each image of Image A and B.
Then, set ‘Edge blending’ to ‘On’ and enter the width of overlap area. (Refer to page 52 for operation procedure.)

✔Note:
•  
The  overlapping  area  might  become  uneven  depending  on  the  images.  In  such  a  case,  it  is  recommended  to 
decrease the contrast of the images in the Image Adjust Menu or set the BrilliantColor function to ‘Off’.
If the colors of the left and right images do not match, then follow the next step.
Select ‘Color matching’ in the setting menu and display the Color matching dialog box.
Then, set ‘Color matching’ to ‘On’ and adjust the color settings (Red/Green/Blue/White). 
(Refer to page 53 for operation procedure.)

Color matching
✔Note:
•   
When you change the values of Target, make sure that each 
Target  value  should  be  within  the  range  of  Measured  value. 
(e.g.,  In  the  case  of  the  Fig.1,  the  X  value  of Target-Red 
should  be  within  0.623  which  is  the  X  value  of  Measured-
Red.)
Set to ‘On’.
5Set ‘Test pattern’ to ‘On’ to display a 50 % white image. The overlap area will be brighter than the non-overlapping 
area. Adjust the Black level in the Edge blending dialog box to increase the brightness of the non-overlapping area so 
that the unevenness is reduced.
Select ‘Advanced color matching’ if you need further adjustment.
In the Advanced color matching dialog box, set ‘Advanced color matching’ to ‘On’ and adjust the values of Target (Red/
Green/ Blue/ Cyan/ Magenta/ Yellow/ White).

Fig .1   For rich color reproduction color wheel
If the colors of the left and right images do not match, even 
if the Target values are adjusted, use a colorimeter which 
is capable of measuring the chromaticity coordinates and 
luminance. Follow the steps below.
1.   Set ‘Auto test pattern’ to ‘On’ in the Advanced color 
matching dialog box.
2.   Put the cursor in the Mesured-White and press the 
SELECT button to display a white pattern.
3. 
 Measure the chromaticity coordinates (x,y) and 
luminance (lx) by using the colorimeter.
4.   Enter the obtained (x,y) values in the Mesured-White. 
(The (L) value of Mesured-White should be left at 1.000.) 
5.   Put the cursor in the Mesured-Red and press the SELECT 
button to display a red pattern.
6.   Measure the chromaticity coordinates (x,y) and 
luminance (Lx) by using the colorimeter.
7.   Enter the obtained (x,y) values in the Mesured-Red. Then, 
calculate the (L) value of Mesured-Red by applying the 
following formula and enter the value.
  (L) value of Mesured-Red = [Lx of Red] ÷ [Lx of White]
8.   Enter the values of Mesured-Green, Mesured-Blue, and 
Mesured-Half white in the same way as Mesured-Red.
9.   Adjust the values of Target again.
10.  Select ‘Store’ to complete. (Apply the same adjustment 
to the other projector if necessary.)
