8.0 ADJUSTING THE IMAGE
64
R599790 - FORCE Series User Manual
maintaining a good overall match of light output from screen-to-screen. By nature, achieving a uniform
brightness will require a slightly reduced overall brightness—this reduction will help ensure that you have
enough range of adjustment when examining brightness variables more closely from screen-toscreen, and will
help prevent premature “maxing out” when trying to match to a certain color, zone or projector.
•
USE A “USER” COLOR TEMPERATURE—Always adjust brightness uniformity for a User color temperature
defined when you matched primary colors, and continue to use it for all sources displayed on the wall. Your other
color temperatures will not necessarily be matched from screen-to-screen.
•
WHITE UNIFORMITY SLIDE BARS—White Uniformity slide bar values may not reduce to “0”. Each slide bar
adjusts overall light output in a specific screen zone, but the value shown represents the current setting for green
in this zone. When other “hidden” values (red or blue) are lower than green, during adjustment in the White
Uniformity menu their values will reach “0” first, causing the slide bar to stop earlier than expected.
•
JUDGE BY EYE OR USE A METER—Good brightness uniformity can be achieved with either.
Diagnostics & Calibration - Submenu
•
TEST PATTERN
Choose the desired internal test pattern to display, or select OFF to turn off a test pattern. Alternatively, use the
TEST key for cycling through test patterns.
•
GREY LEVEL
This will set the level of grey for displaying in the full gray field test pattern.
•
FREEZE IMAGE
Enter a check mark to freeze (stop) an image on a single frame. Use this diagnostic tool to examine in detail a still
version of an incoming image that cannot be “frozen” at the source. For example, in moving images it is sometimes
difficult to observe artifacts such as external de-interlacing/resizing and signal noise. Remove the checkmark to
return to normal.
•
COLOR ENABLED
Select which color(s) you want to see. Use this while working with color temperature, input levels or other special
setup parameters. Colors can be enabled/disabled by entering the corresponding function code listed on the back of
the standard remote keypad.
•
INPUT PEAK DETECTOR
A fast method for defining individual input levels, and improving the accuracy of input levels set by the Auto Input
Level function. Enabling the Peak Detector activates a special operating mode for detecting only pixels that are
considered black or white—all other levels are displayed as a mid-level gray. When used with a 16-step grayscale
pattern in which the two black and white bands 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.
•
INPUT LEVEL DETECTOR
The Input Level Detector check box 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. To use:
1. Enable Input Level Detector and display a continuous grayscale.
2. Set Level Detector Threshold to near black (such as 200).
3. Adjust Offsets to minimize area of black stripe.
4. Set Level Detector Threshold to near white (such as 800).
5. Adjust Gains to minimize area of white stripe.
•
LEVEL DETECTOR THRESHOLD
Input Level Value defines the value to be used by the Input Level Detector in recognizing blacks and whites. See
Input Level Detector, above.
•
ASPECT RATIO OVERLAY
Check this box to display an overlay pattern over the image. The overlay shows the boxes corresponding to the size
and shape of different aspect ratios.
•
TEST PATTERN COLOR SWAP
This function swaps the green and red color when drawing the Grid test pattern, and may be helpful when adjusting
convergence on the projector.
•
CALIBRATE LITELOC
The LiteLoc calibration process must be run to calibrate the LiteLoc sensor on all model types. “Constant Intensity”
mode cannot operate correctly if the calibration has not been performed. The calibration must be done in Dual Lamp
mode, after the lamps have warmed up for at least 5 minutes. NOTE: The shutter will close for the duration of the
calibration, and will automatically open again when the calibration is complete.
