Adjusting the image
Learn how to adjust image geometry so it displays correctly.
Maximizing light output
To ensure optimal operation and peak screen brightness, use LampLOC
™
to adjust the lamp position
when you install a new lamp.
Before running LampLOC
™
, verify the following:
•
The anode yoke is in the correct position for the lamp type.
•
The lamp extension nut is installed when using a CDXL-30SD lamp. Remove the nut if not
using a CDXL-30SD lamp.
•
The lamp is on and the douser is open.
When you complete the LampLOC
™
adjustment, the lamp is centered and is the correct distance from
the illumination system.
1. In the left navigation menu, select Lamp Settings > LampLOC.
2. Select Auto LampLOC.
Calibrating the Intelligent Lens System
On CP2420-Xe/CP4420-Xe projectors, the Intelligent Lens System (ILS) is activated by default.
Use the Auto Calibrate feature of the ILS to find and compensate for motor backlash, and to determine
the movement range for the currently installed lens.
1. In the left navigation menu, select Image Settings > ILS File Setup.
2. From the ILS File list, select an available ILS file.
3. Select Auto Calibrate.
4. Select Continue.
The system performs the lens calibration.
Aligning the image
Aligning the image ensures when it is reflected from the digital micromirror device (DMD) it is parallel
and centered with the lens and screen.
You must complete this procedure before completing a boresight adjustment.
1. Verify the projector is properly positioned relative to the screen (on page 19).
2. Display a test pattern to analyze image focus and geometry.
Christie recommends using the Framing test pattern.
