are known to be at opposite edges of the image, you can watch these isolated areas
while adjusting individual black levels and input drives until both bands are just
visible. Images from this source will then display correct blacks and whites without
crushing or washing out.
NOTE: If using Peak Detector with PIP, both images must have the same color space.

Level Detector

The "Level Detector" checkbox enables specific thresholds for blacks and whites—
input levels that fall below a specified Level Value (see below) are displayed as black,
and all others are displayed as white. It aids in Odd Pixel Adjustment. To use:
1. Enable "Level Detector" and display a continuous grayscale.
2. Set "Level Value" to near black (such as 200).
3. Adjust Offsets to minimize area of black stripe.
4. Set "Level Value" to near white (such as 800).
5. Adjust Gains to minimize area of white stripe.
Level Value
Level Value defines the value to be used by the Level Detector in recognizing blacks
and whites. See Level Detector, above.
Aspect Ratio Overlay
Selecting this option with a checkmark will overlay a number of common aspect ratio
boxes on top of the source image. This is very helpful during the setup of the projector
and can be turned off after desired specifications have been achieved.
LiteLOC™ Calibration
NOTES: 1) LiteLOC™ Calibration takes up to two minutes. 2) For best results, allow
the projector to warm up for 15 minutes prior to calibration.
LiteLOC™ Calibration defines the range of power needed to maintain lamp
brightness. Select Calibrate LiteLOC for calibration using your projector's unique
specifications (recommended) rather than standard specifications. The projector will
revert to the default back-up in the event of a power failure.
Intelligent Lens System (ILS
This option allows you to choose between three types of lens calibrations. Reference
calibration determines a reference point that is used as a defined starting position for
relative motion of the lens. All positioning is measured from this reference point. A
reference calibration is lost when power is removed from the projector and will occur
on every power up as long as ILS™ is enabled. A motion calibration determines the
characteristics of each motor and values are saved in the projector's memory. If ILS™
is enabled and a motion calibration has previously been done, the projector will
automatically recall these settings from memory when it's being powered up and a
motion calibration will not take place. A full calibration performs both a reference
and motion calibration.
