On-Screen Display Menus
The Image Shift menu allows you to precisely center the
image on the screen. (These controls are available only with
a 480i source signal.)
Horizontal: This control moves the image right or left within
the area of available pixels.
Vertical: This option moves the image up or down within the
area of available pixels.
NOTES:
1. To adjust the image position with a 480p or higher-
resolution source, use the
PC & HD Adjust controls in the
Option menu, described on page 38.
2. The values shown represent where the approximate center
of the image lies in relation to the total number of pixels
available horizontally or vertically. This varies widely according
to the signal; watch the image while adjusting.
The Amplitude Adjust menu allows you to fine-tune the
curently-selected image aspect ratio by stretching it horizontally
or vertically, in small increments. This can be useful if your
projector is equipped with an anamorphic lens.
The
Horizontal control adjusts the image width while keeping
the height constant. Similarly, the Vertical control adjusts the
image height while keeping the width constant.
This control compensates for incoming elevated black levels
present in certain video signals, and ensures that blacks in
the display are neither “crushed” (where dark grays appear
black) nor excessively elevated (where blacks appear dark
gray). By default, the projector automatically determines the
best setting according to the type of incoming video signal:
• 0 IRE – Used for DVD output with “enhanced black,”
SECAM, most PAL standards and Japanese NTSC.
• 7.5 IRE – Used for most NTSC video signals.
For some types of video, you may want to override the setting.
Generally, if black appears crushed when brightness = 30,
choose “0 IRE”. If black appears excessively elevated, use
“7.5 IRE”.
Select Lamp Power from the Set Up Menu to adjust the lamp
output level. You can choose to run the lamp as bright as
possible (250W; this is the default setting) or you can choose
the lower (200W) setting. Generally, lower lamp output can
prolong the life of the lamp, but decreases brightness.
