Performing diagnostics and calibration
In
Configuration
>
Diagnostics & Calibration
, configure the following:
•
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—
Set the level of grey for displaying in the full grey 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 check mark 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 grey. When used with a 16-step grey scale 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 display correct blacks and whites without
crushing or washing out. If using Peak Detector with PIP, both images must have the same color
space.
•
Input Level Detector—
Enable 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:
a. Enable
Input Level Detector
and display a continuous grey scale.
b. Set
Level Detector Threshold
to near black (such as 200).
c. Adjust Offsets to minimize area of black stripe.
d. Set
Level Detector Threshold
to near white (such as 800).
e. Adjust Gains to minimize area of white stripe.
•
Level Detector Threshold—
Define the value to be used by the
Input Level Detector
in
recognizing blacks and whites.
•
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—
Swap the green and red color when drawing the Grid test pattern.
This 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 five minutes. The shutter closes for the duration of the calibration,
and automatically open again when the calibration is complete.
