Frame Interpolation
(PowerLite Pro Z8450WUNL/Z8455WUNL only)
The current and previous frames are used to create intermediate frames 
which help to produce smooth-moving images. You can resolve 
clumsy-moving images, such as frames skipping when projecting a fast 
moving image.
The menu is displayed in the following order.
Signal Menu - Frame Interpolation
You can select the level of interpolation: Low, Normal or High. Set to Off 
if noise occurs after setting them.
Super-resolution
You can sharpen the image of a low resolution or blurry picture.The menu is displayed in the following order.
Signal Menu - Super-resolution
Depending on the image, distortion at the edge of the image may be 
enhanced. If you notice any distortion, set it to "0".
q
If you press the [Default] button while adjusting, the value that you are 
adjusting is reset to the default.
Noise Reduction
There are two kinds of noise reduction functions:
•Noise Reduction
•Mosquito NR

Settings for Multiple Projectors
When projecting to a wide screen from multiple projectors, you can 
adjust the difference of brightness and color tone between the edges of 
each projected image (Edge Blending), to create a seamless screen.
There are two general methods of projecting from multiple projectors.
Preparation Flow
The following is an example of using method U. (Method V follows the 
same basic flow except you use the scale function to adjust the position of 
the projected image sp.181)
Settings are explained here using the remote control, but they can also be 
set by the control panel.
Requirements
•Two or more projectors that support Edge Blending
•A dedicated computer with a GPU that has two or more outputs (VGA, 
DVI, HDMI, etc.) and supports Edge Blending
•Cables to connect the computer to the projectors
Projector ID/Remote Control ID
When an ID is set for the projector and the remote control, you can use 
the remote control to operate only the projector with a matching ID. This 
is very useful when managing multiple projectors.
When operating all of the projectors from the remote control, set the ID 
switch on the side of the remote control to Off.
UProjecting different images from each projector, and creating a 
seamless screen
VProjecting the same image from each projector, using the Scale 
function to project a large image

•Operation using the remote control is possible only for projectors that are 
within the operating range of the remote control. s"Operating range of 
remote control" p.23
•When Remote Control Type is set to Simple from Operation in the 
configuration menu, you cannot set the remote control ID. sp.67
•IDs are ignored when the projector ID is set to Off or the remote control ID 
is set to 0.
Setting the projector ID
ProcedureA
During projection, press the [Menu] button and select 
Extended - "Multi-Projection" from the configuration menu. 
s"Using the Configuration Menu" p.55
B

C
Select of one of the numbers from 1 to 9 to use as the ID and 
then press the [Enter] button.
D
Press the [Menu] button to close the configuration menu.
Checking the Projector ID
Use the following procedure to check the projector ID.

Procedure
A
Set the remote control ID switch to On.
B
During projection, while holding the [ID] button, press the 
[Help] button.
When you press the buttons, the current Projector ID is displayed 
on the projection screen. It disappears in about three seconds.
Setting the remote control ID
ProcedureA

While holding the [ID] button, press a number button to 
select a number to match the ID of the projector you want to 
operate. s"Checking the Projector ID" p.174

q
The remote control ID setting is saved in the remote control. Even if the 
remote control batteries are removed to replace them and so on, the stored 
ID setting is retained. However, if the batteries are left out for a long time, 
it is reset to the default value (ID0).
Adjusting the Position of the Projected Image
Adjust the position of the projected image, starting from the adjustments 
that have larger corrections. For the best results, use physical adjustments 
(moving the projector’s position, optical zoom, and lens shift) as much as 
possible to minimize the amount of digital correction (Quick Corner, 
Point Correction, H/V keystone, etc.) needed to correct your images.
q
•We recommend setting the focus, zoom, and lens shift at least 30 minutes 
after you start the projection, because images are not stable right after 
turning on the projector.
•The Test Pattern can be displayed to adjust the projection status without 
connecting video equipment. sp.157
•When projecting from multiple projectors, correction is easier if images are 
displayed as is (aspect ratio and image resolution are maintained) and 
without being enlarged or reduced in size.]
•We recommend projecting from the center of the lens when possible. As you 
get to the edges, the lens gets thinner which can cause distortion and affect 
the quality of the blend.
Point Correction
Corrects slight distortion which occurs partially, or adjusts the screen 
position in an overlapping area when projecting from multiple 
projectors.
A grid is placed on top of the projected image and you can move the 
points of intersection on the grid left, right, up, or down to correct 
distortion.
ProcedureA
During projection, press the [Menu] button. Select Settings 
menu - "Geometric Correction" and then press the [Enter] 
button. s"Using the Configuration Menu" p.55
