3.6 Convergence
Registration
Convergence Registration is the process of aligning the red, green, and blue
color components on the projection screen. The projector’s convergence sys-
tem provides accurate color registration in 45 discrete convergence zones con-
figured in a 9 by 5 array on the projection screen. Since the projector must
converge colors differently for each source (due to varying scan frequencies),
convergence settings are saved for each input. Convergence settings can also
be saved in Recall memories.
There are three basic convergence methods available: Guided, Interpolated,
and Random Access. Any one of these can be selected for performing a
registration adjustment. All are easy to use and context-sensitive help is
available if needed. With the ACON feature, the convergence process is
completely automated. ACON provides fast, accurate convergence, and
is especially helpful when many inputs must be converged, or when the
projector installation position frequently changes.
To perform a convergence:
Begin by selecting the input source to be
converged. Convergence settings will be saved
in the current setup memory. Next, press
to display the Convergence menu. Select
one of the convergence options from the menu.
Guided Convergence provides a complete
guided convergence of the red and blue images
onto the green image in all 45 convergence
zones. Use this option if the image requires
minor convergence alignment and you wish
to be guided through the 45 convergence zones.
Interpolated Convergence provides a complete convergence similar to
Guided but is recommended when the image requires major convergence
alignment (and should be used the first time a source is converged).
Random Access Convergence allows you to converge a particular area of the
display. Any zone may be quickly selected and converged. This option also
allows convergence of the blue on the red image (if preferred to the normal
blue on green).
ACON is a feature that provides fast, accurate automatic convergence in
all 45 convergence zones. Minimal user intervention is required. If the
projector does not include ACON, item 4 in the menu reads “ACON
(not installed).”
The Service selection is used to access the convergence service utilities.
These utilities are provided for qualified service personnel only. (Password
access is required).
