Adjustments
Adjustments can be performed on individual colors if the RGB letters
are in the window on the screen. Selecting one (1) color makes it
adjustable but all three (3) colors still remain on the screen (unless
hidden by the H
IDE
key).
Pressing E

etc. up/down arrow keys are

also accomplish the same adjustments.
After completing the timing, geometric, and convergence adjustments for one (1)
source, the adjustment data may be backed up by copying the channel to another
of the 99 channels and the source file to another of the 20 sources.
NOTE: When backing up a channel, ensure that the “copied to” channel is blank.
Channel paste is only allowed to “cut” empty channel. Source paste will overwrite
current source geometry, convergence and ILA
®
settings. All data will be deleted
on the “copied to” channel. Refer to the Backing up Settings function from Section
4.10 on page 4-38 for more detail.
This provides backup for a previously set up channel and a good starting point for
setting up other channels. Also ensure that the "copied to" channel uses the
same type of VIC as the "copied from" channel. If the projector uses only one (1)
VIC, this is not applicable.
