Operation
58 Vidikron Vision Model 65/Model 75 Installation/Operation Manual
VAC: Use the VAC control to increase or decrease the V ² Aperture Control setting. VAC lets
you control the aperture or iris size (the physical opening through the lens; similar to an
“f-stop” on a camera). Doing so allows you to optimize brightness and contrast according to
the amount of ambient light in the viewing area.
Use a higher setting for rooms with a lot of ambient light. Use a lower setting for more
“theater-like” viewing conditions (little or no ambient light).
12-volt Trigger: Select 12-volt Trigger from the Setup menu to configure the 12-volt trigger
output.
• Set the 12-volt Trigger to Normal if you want the trigger to activate when the projector is
turned on (for instance, if the trigger is controlling a retractable screen).
• Set the 12-volt Trigger to Cinema if you want the trigger to activate when the Cinema or
IntelliWide 2.35 aspect ratio is selected. Choose this setting if your Vision 65/75 is
equipped with the Vidikron CineWide with AutoScope system.
V. Correction: To achieve the proper image geometry with the secondary anamorphic lens,
select V. Correction from the Set Up menu. Then, use the
or button to change the
native aspect ratio of the display, in small increments.
Amplitude: The Amplitude menu allows you to fine-tune the aspect ratio by compressing 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.
Auto Off: When using the Vision 65/75 with a computer, use the Auto Off feature to have
the Vision 65/75 go into standby mode when no source signal is present on the current
input. (A warning message appears on-screen for approximately eight seconds before this
occurs.) Select an Auto-Off interval of from five to 30 minutes, in five-minute increments. To
return to normal operating mode from the Auto Off standby mode, select the input with the
remote control or operate your computer.
When Auto Off is disabled, the Vision 65/75 remains in normal operating mode, regardless of
the presence or absence of an input sync signal.
Default: To restore all Setup Menu options to their factory-default values, select Default and
press the
button to highlight “Yes.” Then, press ENTER.
1. If the computer is turned off or not properly connected to the Vision
65/75, the system is set to the off state.
2. For instructions on using the computer's power management features,
refer to the instructions for your computer.
