Section 3: Operation
On each projector you must set the following:
• The tiling array size - set the total rows and total columns. This setting will be the same on all the projectors
in the array.
• The relative location of the projector within the array - set the row number and column number for each
projector
• Enable Tiling - can be enabled or disabled without losing any of the above settings.
NOTE: The Frame Delay Compensation function in the Tiling menu will cause the system to attempt to
automatically correct for frame delay issues which may occur in 3 row tiling. When this check box is set, and
using 3 row tiling, the manual frame delay control is disabled.
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
configuration. 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.
NOTES: 1) When the FUNC+HELP key combination is pressed, the tiling settings will be cleared. 2) Tiled
warps/keystones can be enabled through Christie TWIST 1.6; See the Christie TWIST User Manual.

• Test Pattern: Choose the desired internal test pattern to display, or select OFF to turn off a test pattern.
Alternatively, use the T
• 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 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 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 grey scale.
2. Set Level Detector Threshold to near black (such as 200).
