Aligning The Image With Lens Zoom And Focus; Adjusting Digital Micromirror Device (Dmd) Convergence - Christie Griffyn Series Installation And Setup Manual

7. To continue to refine the fold mirror adjustment, repeat the horizontal and vertical
adjustments.
8. Lock the fold mirror screw to lock the adjustment knobs.
9. Once satisfied with the alignment, increase the projector power.

Aligning the image with lens zoom and focus

The lens zoom and focus adjustment allows the projected image to be focused and shifted to align
with the screen.
1. Display an image or test pattern that can be used to analyze image focus and geometry.
2. Select ZOOM.
3. Use the up and down arrows to zoom in or out of the image.
4. To exit, select Back.
5. Select FOCUS.
6. Use the up and down arrows to adjust the focus of the image.
7. To exit, select Back.
8. To refine your adjusts, repeat steps 2 to 7.

Adjusting digital micromirror device (DMD) convergence

A convergence problem occurs when one or more projected colors (red, green, and blue) appears
misaligned when examined with a convergence test pattern.
Two features can be used independently or in conjunction to adjust convergence: electronic (with the
remote or through the menu) and/or mechanical.
When adjusting the convergence, you are adjusting red and green to blue for mechanical
convergence. For electronic convergence all three colors can be adjusted. Always align the color
components of the sprite to the inner most line color (for each axis). The three colors should overlap
to form pure white lines throughout the image and one or more poorly converged individual colors
may appear adjacent to some or all of the lines.
For best convergence results, Christie recommends disabling all geometry and color (set the color
correction mode to Max Drive) correction before adjusting convergence.
If you wear glasses with corrective lenses when performing this adjustment, make sure you are viewing
the test pattern on a straight angle through the optical axis of your glasses, and not from a tilted or
angled perspective. This avoids a prismatic effect that can appear to shift convergence when viewing at
an angle.
