e) Once all the color sensor and measured values are entered for all nine rows, select Apply
and Save.
8. Verify and complete the calibration.
a) Select a white point to measure by selecting either the DCI, D65, or Custom white point
buttons.
Once selected, the projector automatically enables LiteLOC, selects a White test pattern
with uncorrected colors at the white point specified, and sets the brightness to 80%.
b) Using a spectroradiometer, measure screen X and Y values at the center of the screen.
To verify the calibration has been successfully applied, the measured white point must be
within the expected tolerance.
c) When complete, select Finish.
The projector output is configured according to the currently selected calibration file and
you are returned to the Sensor-to-screen Calibration menu.
Recalibrating an existing calibration file
The Sensor-to-screen Calibration wizard guides you through the steps required to re-calibrate an
existing calibration file, if required.
1. Select Menu > Color Settings > Sensor-to-screen Calibration.
2. Select a user-defined calibration file to recalibrate.
3. Select Recalibrate.
The projector checks if the light source is on and the douser is open. If either condition is not
met, a warning dialog is displayed prompting you to make sure these conditions are met
before starting the wizard.
4. In step 1 of the Sensor-to-screen Calibration wizard, set the maximum brightness and color
point.
a) Enable the Display White Test Pattern option.
b) To set the maximum expected room and chiller (for chiller-based products) temperatures,
use the plus (+) or minus (-) signs.
c) Adjust the RGB sliders to set the brightness and color point.
d) Select Next.
5. Wait 20 minutes for the projector to stabilize or select Skip during the stabilization time
period.
6. In step 2 of the Sensor-to-screen Calibration wizard, measure and enter the screen values.
a) To trigger the measurement at a specific operating point, under Sensor to screen, select
Capture.
The Capture button changes color to indicate the capture process is activated. Only one
Capture button is active at a time but the buttons can be selected in any order.
The projector automatically sets the red, green, and blue output laser powers to the pre-
determined settings calculated and displayed in the Drive Percentage (Calculated) area of
the wizard.
A 10 second countdown begins to allow the projector white point and brightness to
stabilize and no changes can be made. At the end of the count down period, the Color
Sensor values fields are automatically populated by the projector for the currently selected
drive percentage value.
