across the whole image, adjust the convergence to perfectly align the three panels so that all pixels
line up. Read this entire section before adjusting convergence.

Before convergence
•
Make sure image zoom and centering is complete.
•
Make sure boresight procedures are completed.
•
Allow the projector to warm up for 15 minutes to reach nominal operating temperature.
•
During convergence, the lid and/or filter side of the projector is open, causing decreased prism
cooling performance and possible shifts in convergence or DMD focus. The prism temperature
must be monitored during the adjustment and kept within a few degrees of the nominal
temperature achieved above by lowering the laser power or periodically replacing the cover for
a cool-down.
•
If the procedure takes longer than an hour, watch for over-temperature alerts. Cool-down
periods with the douser closed and cover on may be required.
•
Typically the blue image component can be used as the fixed reference, so no adjustment is
required. However, if you need to adjust the blue image component it is easy to adjust, but the
side panel must be removed. The recommended normal convergence adjustments are from
green to blue and red to green.
•
Christie recommends that the vertical and rotation adjustment be done first, as they work
dependently together, and the horizontal adjustment done last.
•
Use extreme caution to not damage any electronic components.
