5Select [Start position] and use the remote’s [ ] [ ] buttons to move the 
markers to the right edge where the images overlap.
6Select [Width], and use the remote’s [ ] [ ] buttons to move the markers 
to the overlapping area.
The area between the starting and ending markers is called the blending area. 
Brightness of this area is automatically adjusted to match the brightness of 
other image areas. After you complete settings for the left image, do the same 
thing for the right image, to specify the blending area along the left edge. Adjust 
the area so that the blending area for the left and right images is the same.
7Set [Marker] to [Off].
Edge Blending with Four Projectors
Specifying a large blending area may cause dialog boxes for input signal selection or 
status to be covered by the blending area. In this case, momentarily switch edge blending 
from [Adjust] to [Off], check the display, and then return the setting to [Adjust].
Although the starting marker is normally aligned with the image edge, it can also be 
aligned more toward the center of the image. In this case, the black blending area will lie 
outside of the starting marker.
Example: When specifying the blending area for the 
lower-right image, configure the settings for 
blending areas along the top and left image 
edges.
Complete the settings for the other three 
images the same way for the edges that 
overlap.
Images from four projectors can also be blended, as 
shown at left.
Specify the blending area where each image overlaps 
with others.

■Advanced Instructions: Black Level Adjustment
In overlapping projection, dark colors are projected with less intensity than other 
colors in the overlapping area. For this reason, overlapping image areas might be 
more noticeable when the images themselves are dark. You can make this 
overlapping area less distracting by adjusting the black level of non-overlapping 
image areas.
Here, the non-overlapping image area (from the end marker toward the center of 
the image) is called area “D.”
Normally, three areas are identified in the context of end markers: A, B, and C.
In the following instructions, only area D is adjusted, and the widths of A, B, and C 
are left at the default value of 0.
1On the edge blending screen of step 2 in “Basic Instructions” (P159),
select [Black level adjustment] > [Adjust].
The black level adjustment window is projected.
• To prepare for adjustment, set [No signal screen] to [Black], start projection with no input 
signal, and turn off the room lights, so that you can check dark image areas. (P109)
• Set [Marker] to [Off].

Here, you can use the following settings in the edge blending menu.

3Select [D-area base], and use the remote’s [ ] [ ] buttons to adjust the 
values for area D.
As you watch the image, adjust the values so that the brightness and colors of 
the blending area and area D match. Adjust [D-area base] to lighten the black 
level, and adjust [Red], [Green], and [Blue] to obtain an optimal black level 
color tone, as needed.

■Advanced Instructions: Smoother Overlapping Areas
Adjustments to areas A, B, and C may make the black level along the right edge of 
area D (that is, the edge bordering the blending area) more noticeable than that of 
surrounding areas.
To compensate, adjust each area as follows.
When there are multiple blending areas relative to the projected image (on all 
edges), you must adjust the width of areas A, B, and C.
In this example, instructions are given for adjusting area B.
1In the window of step 2 in “Advanced Instructions: Black Level 
Adjustment” (P162),  select [Adjustment type] > [Area] > [Side] > [Right].

2Select [B-width], and use the remote’s [ ] [ ] buttons to specify the width 
of area B.
This will make the width of area D narrower.
3Adjust the width of area B to roughly match the area where the black level 
is noticeable, and then use the following edge-blending settings to adjust 
the black level of area B.
Adjust the black level of area B the same way as you adjusted it for area D.
For adjustment instructions, see “Advanced Instructions: Black Level 
Adjustment” (P162), step 3.
4Fine-tune the position and width of area B.
5As you watch the image, adjust the width of areas A, B, and C.
6Readjust the black level of area B, as needed.

button.

B-area base Adjust the area B black level.
B-area red Adjust the red component of the area B black level.
B-area green Adjust the green component of the area B black level.
B-area blue Adjust the blue component of the area B black level.
Results of adjusting the black level of area B are applied to all sides.
However, adjusting [Contrast], [Screen color], or other settings may not eliminate 
distractions in image boundaries.
• To simplify adjustment, use the same lens shift position and image mode (ideally, 
[sRGB]) on each projector.
• For best edge-blending results, perform the following adjustments.
(1) Black and white adjustment by adjusting R/G/B gain and offset (P101)
(2) Gamma adjustment by fine-tuning gamma (P105)
(3) Color adjustment by using 6-axis color adjustment (P104)
• To reduce distracting colors or differences in brightness where images overlap, try 
darkening images by adjusting [Contrast] (or other [Image adjustment] menu settings) 
or [Screen color].

Network Connection Overview
Connecting the projector to a network enables you to control the projector from a 
computer and receive notification of projector errors via email. Settings related to 
the network connection can be made from either the projector side (P169) or 
computer side. (P178)
Depending on the method of network connection, preparation on the computer side 
may be necessary. The following is an explanation of preparation on the computer 
side.
Connection Methods
Connect the projector to the computer via LAN.
•When the [Network function] setting of the projector is set to [Off] (Network 
Connections is disabled), switch it to [On] to enable it. (P171)
•Referring to “Checking Projector Information” (P122), check that the projector IP 
address does not overlap with other computers that are on the same LAN. To set 
a projector IP address, follow the instructions in “Completing Computer Settings” 
(P178) and use the web screen, or use projector TCP/IP settings. (P174)
•When you connect the computer to the network for the first time, it is also 
necessary to perform settings on the computer. In this case, consult the network 
administrator regarding the necessary settings.
For details on networked multi-projection – projecting images from computers through 
one or more projectors over a network – see “Networked Multi-Projection.”
In a network environment where a DHCP server is operating, choose [On] on the 
projector [DHCP] screen to enable the DHCP function and connect it. (P174)
