Automatically Correcting Frame Delay Issues In Tiled Images; Refining The Displayed Colors - Christie M Series User Manual

In a multiple-projector wall, you want to precisely match color and intensity from image-to-image so
that the full wall is as uniform as possible.
1. To achieve consistency use a color meter to measure the native primary colors (red, green,
blue, and white) as they appear at the screen.
2. In the Service menu for each projector, record these as Color Primary Settings.
On the basis of these new values, which are stored in memory, each projector then
automatically calculates any necessary corrections to reproduce the original factory colors
under the current environmental conditions. This calibrates a projector to its surroundings,
compensating for factors such as screen type, lamp and/or ambient lighting, and improves
color accuracy and consistency in a group of projectors. It ensures a good starting point for
further customizing and matching; however, is not critical for all installations.
3. To return the primaries to the factory-set color, in the Service menu select Color Primaries >
Reset to Factory Defaults.
4. Repeat the calibration process and continue with matching of colors.
Automatically correcting frame delay issues in
tiled images
Frame delay compensation attempts to automatically correct for frame delay issues which may occur
in three row tiling.
When enabled, and using three row tiling, the manual frame delay control is disabled.
The features that act differently when Tiling is enabled are:
• The picture-in picture border is disabled.
• Cascading menus are turned off.
• Menus show only five 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 with 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.
1. To clear tiling settings, press FUNC+HELP.
2. Enable tiled warps and keystones through Christie Twist.
Refer to the Christie Twist User Manual (020-101380-XX).

Refining the displayed colors

In a multiple-projector wall, match color and intensity from image-to-image as precisely as possible so
that the full wall is uniform.
Once the Color Primary Settings are calibrated for the site, use the Color Adjustments by X,Y or Color
Saturation menu to further refine each projector's fundamental colors so that the hue and intensity of
each color appears the same from one display to another. Once matched, you have created a single
new shared range of colors or color gamut that all of your projectors can produce. This palette—
