2. Set Level Detector Threshold to near black (such as 200).
3. Adjust Offsets to minimize area of black stripe.
4. Set Level Detector Threshold to near white (such as 800).
5. Adjust Gains to minimize area of white stripe.
• LEVEL DETECTOR THRESHOLD
Input Level Value defines the value to be used by the Input Level Detector in recognizing blacks and whites. See
Input Level Detector, above.
• ASPECT RATIO OVERLAY
Check this box to display an overlay pattern over the image. The overlay shows the boxes corresponding to the size
and shape of different aspect ratios.
• TEST PATTERN COLOR SWAP
This function swaps the green and red color when drawing the Grid test pattern, and may be helpful when adjusting
convergence on the projector.
• 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 the calibration is complete.
• FREEZE IMAGE DURING AUTO SETUP
If selected, this will hide temporary image artifacts that may appear during the auto setup procedure.
Option Card Settings - Submenu
Allows adjustment of any settings specific to each option card that is currently installed in the projector.

8.5 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 to match colors.
To achieve consistency use a color meter to measure the native primary colors—red, green, blue, and white—as
they appear at the screen. Record these as Color Primary Settings in the Service menu (password-protected) for
this unit. On the basis of these new values, which are stored in memory, each projector will then automatically
calculate any necessary corrections to reproduce the original factory colors under the current environmental
conditions. This essentially calibrates a projector to its surroundings, compensating for factors such as screen type;
lamp and/or ambient lighting and will improve color accuracy and consistency in a group of projectors. It ensures a
good starting point for further customizing and matching; however, is not critical for all installations.
To access the Service menu (password-protected) return to the factory-set color primaries. Select the “Reset to
Factory Defaults?” option in the Color Primaries submenu. Then repeat the calibration process describe above and
continue with matching of colors.
8.6 Color Adjustment Procedure
Once the Color Primary Settings are calibrated for the site, use the Color Adjustments by X,Y or Color Saturation
menu to further refine each projector’s fundamental colors so that the hue and intensity of each color to match the
desired Test pattern colors.
Color Adjustment by X/Y
Enter known x/y coordinates from the chromaticity graph
NOTES:
1) For defining or changing a User 1, 2, 3, or 4 color performance or “gamut”. Sometimes known as Comprehensive
Color Adjustment™.
2) Factory-defined primary color levels, which ensure a specific color performance from projector-to-projector, can
be calibrated in the Service menu only. The factory settings can be recovered with selection of “Reset to Factory
Defaults” in the Color Primary Settings submenu accessed via the Service menu (password protected).
From the factory, the projector can utilize any of the three pre-defined color performance settings identified at right
(default=Max Drives), or colors can be driven on the basis of color temperature. For most applications, one of these
gamuts will produce accurate and realistic colors from a variety of sources. They can be applied at any time in the
