Section 3: Operation

Defining the Size of	' Use the Tiling Setup submenu to define the size of a wall (number of rows and
a Display Wall	columns), and identify the location of each projector in the wall. If you are
	operating a stand-alone unit, enter “1” for items 1 to 4.

Matching Colors of	' For the image on a display wall to appear seamless, color and brightness must be
Multiple Projectors	precisely matched from screen to screen. This requires the adjustment of the
	projector’s primary colors from the Adjust Primary Colors menu.
	NOTE: Projectors manufactured later than August 2005 are color-adjusted at
	the factory to reduce adjustment time at site. Thus projectors should closely
	color-match following installation. Only minor adjustment should be required.
	Use the procedure below to ensure you achieve a uniform display.
	When matching screens in a display wall, do the following:
	NOTES: 1) It is recommended that you begin this procedure with all projectors
	at the same power level - 100W recommended setting. 2) Look at the center of the
	screen when performing this procedure. 3) A color meter can be used, but is not
	required to successfully perform this procedure. 4) Color matches are optimized
	for graphic sources. If using video sources with over-adjusted primary colors,
	you may notice a slight posterized or banded effect in images. 5) It is
	recommended that you look at the white color temperature again after installing
	a new lamp.
	Step 1: Preliminary Setup
	1a) Setup and optimize all projector settings – Optimize projector settings
	without trying to match color temperature or perceived light output at this
	point. E.g. Adjust size, position, and geometry.
	1b) Assign projector ID numbers – Make sure each projector is assigned a
	unique 2-digit number. This allows you to switch between communicating to
	one projector or all projectors.
	1c) Display a 16-step grey scale test pattern with black on the left and white on
	the right with 16 equal sized levels and run the Auto Input Level option.
	NOTE: Test patterns are provided on the CD found in the User’s Kit.
