Diagnostics & Calibration - Submenu - Christie J Series User Manual

Section 3: Operation
The features that act differently when Tiling is enabled are:
 The PIP border is disabled
 Cascading menus are turned off
 Menus show only 5 items, with a scroll bar to allow the rest of the menu items to be reached.
 Projector source switching in the array is not synchronized. Therefore some latency can be seen from when
the commands are issued to each projector, causing switching to not be as seamless when in a tiling config-
uration. When using loop-through via the Twin HDMI Input Card to distribute a signal to the tiling array,
additional latency in the switching can occur during HDCP repeater negotiations with the source player.
HINT: When the FUNC+HELP key combination is pressed, the tiling settings will be cleared.
NOTE:
Tiled warps/keystones can be enabled through Christie TWIST 1.6; Refer to the Christie TWIST User
Manual.
3.8.9 DIAGNOSTICS & CALIBRATION - Submenu
• TEST PATTERN
Select the desired internal test pattern to display, or select OFF to turn off a test pattern. Alternatively, use the
T
EST
key for cycling through test patterns.
• GREY LEVEL
This will 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
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 grey. When used with a 16-step
greyscale 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.
