On-Screen Display Menus
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 image
aspect ratio by stretching it horizontally or vertically, in small
increments. 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.
The Remote Control menu shows you the primary and
secondary infrared (IR) codes assigned to the CL-610. The
Primary IR code is permanently set to +20. The secondary
IR code is also +20.
You can change the secondary IR code if either:
• Another device in the theater (a DVD player, for example)
is responding to commands from the CL-610 remote
control in ways that are unpredictable or undesirable.
• You have multiple CL-610 projectors and want to
control them independently, as opposed to broadcasting
commands from a single remote to all of them. In this
scenario, you can use multiple remotes programmed to
