Advanced Image Settings
DECODER LUMA DELAY - This option
affects any incoming composite or S-video sig-
nal, delaying the luma signal (intensity) in rela-
tion to the chroma (color). In the image,
increasing the luma delay will move luma (seen
as a shadow where colors overlap) to the right
slightly, with colors remaining in place.
Decreasing this delay will move the shadow slightly to the left. If necessary, adjust so that no
shadows occur with adjacent colors.
INPUT VIDEO BLACK - This option determines where black levels are determined in rela-
tion to the clamping location on a video signal, so that blacks are neither crushed (i.e., with
dark gray appearing black) nor elevated (i.e., with black appearing dark gray). If black is
crushed in the current image, set to "0 IRE" so that blacks are at the clamping level. If black is
elevated, set to "7.5 IRE" so that blacks are set above the clamping level.
VCR - This option determines to what degree the projector tolerates signal disturbances. The
correct setting is automatically determined and set according to the type of incoming source
signal-for instance, there should be a checkmark for all VCR sources. The VCR option may
require a change from its auto setting in very rare circumstances only, such as if you are having
difficulty switching between two unusual and almost identical VGA computer sources.
Otherwise, it is not necessary to change this option.
MOTION FILTER - This option is most useful for smoothing out de-interlacing artifacts that
sometimes occur with moving interlaced images (such as HDTV). By default, the correct set-
ting is automatically determined according to the type of incoming source signal. If desired,
override the default setting as follows:
1.
Turn to OFF (delete the checkmark) if you have a static image.
2.
Turn to ON (enter a checkmark) if your mov-
ing image exhibits motion artifacts. The image will be
smoother while forfeiting some sharpness.
Lamp
Whenever you install a new lamp in the projector you need to
access the Lamp submenu and record the lamp serial number
in the projector's memory. You can also set different Lamp
submenu options such as intensity (output) or power required.
These setups can be changed at any time.
NOTE: See 4.4, Replacing the Lamp and Filter for complete
instructions on installing a new lamp in the projector.
From the Advanced menu, select the "Lamp" option for access to the Lamp submenu, where all
lamp functions and data appear. Read-only information includes the number of hours logged on
the lamp so far and the serial number recorded for the installed lamp.
