ADVANCED EDGE BLENDING - SUBMENU
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”...

5. Re-adjust width (both projectors) until the overly bright band at the midpoint of the overlapping blends 
disappears or just changes to very light grey. For the shared edge, use the same Blend Width setting on 
each projector. 
NOTE: If the best blend appears to be between two settings, choose the wider setting for 
both projectors.

 Use this submenu to create, alter or copy a color gamut (i.e., “color adjustment”). Controls in this menu define 
the precise hue of each primary color component (red, green, blue, and white) used to generate the millions of 
colors produced in displays. The x/y coordinates for each color define its location on the standard CIE 
chromaticity graph, see Figure 3-36 CIE 1931 Chromaticity Diagram. Changing either or both...

BLACK LEVEL BLENDING - SUBMENU
Eliminates the differences between black levels when edge blending multiple projectors. The Black Level 
Blending submenu provides many controls to allow the edges of adjacent images to be smoothly overlapped 
creating a “seamless” image. (Edge blending smooths white levels, and if edge blending is not in use, Black 
Level Blending is disabled.) 
NOTES: 1) Adjust white levels before...

NOTES: 1) The menu options vary depending on the edge blending parameters. 2) You may need to re-adjust 
the black level hues following the overlap adjustments on each blended edge.
 3) When adjusting six or more 
projectors, you need to ensure that the hue and brightness of each target area is matched at closely as possible.

•CALIBRATE LITELOC 
The LiteLoc calibration process must be run to calibrate the LiteLoc sensor on all model types. “Constant 
Intensity” mode cannot operate correctly if the calibration has not been performed. The calibration must be 
done in Dual Lamp mode, after the lamps have warmed up for at least 5 minutes. 
NOTE: The shutter will close 
for the duration of the calibration, and will automatically open again when...

LAMP MODE
Determines how the lamp’s power and intensity are controlled. If Maximum Brightness the lamp burns as 
brightly as possible. Select Constant Intensity mode to maintain a specific brightness level over time. As the 
lamp ages, the projector will increase power as needed, to closely maintain the required output from the lamp. 
Select Constant Power to specify the power level supplied to the lamp. Both Constant...

CHANGE LAMP - Submenu
Initiates the lamp change process for the selected lamp and allows the serial number of the new lamp to be 
entered.
Lamp serial numbers are used for keeping statistics on each lamp used in each lamp position. Entering of serial 
numbers is optional, but is recommended. 
When using this function, the statistics from the previous lamp are archived, and starts statistics tracking for 
the new lamp. If...

Preliminary Calibration
All primary colors in the projector are precisely set to pre-established values to ensure that overall color 
performance is optimized and is as accurate as possible. Lighting and other environmental factors may slightly 
change how these colors appear on your screen. While the change is negligible in most cases, you may prefer 
to recover the originally intended color performance before trying...
