Christie recommends using the lens offset to align the center of the image to the center of the
screen before correcting the keystone effect.
3. If one side of the image is longer than another, adjust the tilt and level of the projector.
Displaying a test pattern
Display a test pattern to refine and adjust the projected image or to diagnose and correct image
issues.
1. In the right toolbar, select Test Patterns.
2. Select Full Screen.
3. Select a test pattern.
When a test pattern is active, a blue bar appears below the test pattern icon in the right pane.
4. To display a 2D test pattern in 3D mode, select the 3D Sync option.
The 3D Sync option is selected automatically for 3D test patterns. 3D test patterns cannot be
displayed in 2D mode.
5. To change the frame rate of the test pattern display, select from the available Frame Rate
options:
•
For 2D test patterns, the available frame rates are 24, 30, 48, and 60 Frames Per Second
(FPS). The default value is 24 FPS.
•
For 3D test patterns, the available frame rates are 48 and 60 FPS. The default value is 48
FPS.
Changing the frame rate of the display can assist with color measurement when working with
corrected colors.
When changing the frame rate option, the option is applied to the next test pattern you select
unless it is not available for that pattern. If a selected frame rate is not available, the default
frame rate is applied for the test pattern display.
Adjusting the integrator rod and fold mirror
Understand how to adjust the integrator rod and fold mirror to control the illumination spot on the
DMD.
Extreme misalignment of projection optics can cause permanent damage to critical optical
components. Only Christie qualified technicians can perform internal optical adjustments.
The integrator rod and fold mirror adjustments are set by Christie. Make adjustments only if screen
shadows are visible.
When adjusting the fold mirror, set the light source to minimum power.
1. In the right toolbar, select Test Patterns.
2. Set the Red/Green/Blue power to less than 40%.
High power and misalignment can damage the DMDs.
3. Select the RGB-4K-Integrator Rod test pattern and display it full screen.
