Front IR / Back IR 
As needed for your application, set to “any” so that the front and/or rear IR sensor 
locations on the projector respond to the IR keypad. Set to “off” to disable. 
To disable both IR sensors, you cannot use the IR remote keypad to select the second 
OFF setting. This safeguard prevents accidentally disabling an IR keypad while you 
are using it. Instead, use...

Brightness Uniformity — SUBMENU 
Brightness Uniformity provides further refinement of displays already matched for 
their primary colors and overall light output. Use Brightness Uniformity to create an 
exceptionally smooth image in which no area appears brighter and/or more red, green 
or blue than another. In the Brightness Uniformity menu, enable the “Uniformity 
Enable” checkbox to access a multitude of adjustments for critical color light output...

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.

PROCEDURE FOR X,Y ADJUSTMENTS:  See 3.11, Using Multiple Projectors. 
COLOR SATURATION: Use this 
submenu if you do not have 
specific color coordinates in mind 
and will simply judge color 
performance by eye or meter. 
Like the Color Adjustment by X,Y 
submenu, each color control 
actually defines new x/y

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 Level Blending is disabled. Black Level 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...

Test Pattern 
Choose the desired internal test 
pattern to display, or select OFF 
to turn off a test pattern. 
Alternatively, use the 
Te s t key 
for cycling through test patterns. 
NOTE: There is a center line 
(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.

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 2 different inputs.

NOTES: 1) Adjust offset before gain, since offset affects gain. 2) A value of 128 
represents no change in normal odd pixel offset or gain. 3) Odd Pixel...

LiteLOC™ Calibration 
NOTES: 1) LiteLOC™ Calibration takes up to two minutes. 2) For best results, 
allow the projector to warm up for 15 minutes prior to calibration. 
LiteLOC™ Calibration defines the range of power needed to maintain lamp 
brightness. Select Calibrate LiteLOC for calibration using your projector’s unique 
specifications (recommended) rather than standard specifications. The projector will 
revert to the default back-up in the event of...

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...

Other PIP or Seamless Switching tips to keep in mind include: 
• When using 2 digital signals or 1 analog and 1digital, 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)...
