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

CONV 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).
