Texas Instruments MATRIX 3000, DW30 user manual Using Multiple, Projectors, In Multiple Screens

Section 3: Operation

The read-only Status menu lists a variety of details about the standard and optional

3.9 Status Menu components currently detected in the projector. Refer to the Status menu for versions of hardware and software installed, the type (size) of lamp, the hours logged in total and for a specific period (such as a rental period), and for your projector model name and serial number. In addition, the Status menu identifies the current channel, its location, its frequencies and other details.

		Scroll the full Status menu using	. Use	for page up/down.
		When an installation requires multiple projectors, you can use the RS232 serial ports
	3.10 Using Multiple
		to daisy-chain the units together and control the group with a single keypad or a
	Projectors	computer/controller connected to the first projector. In such a network, you can
		choose to broadcast commands to the entire group, or use the Proj key as desired to
		limit responses to an individual projector.
		Alternatively, you may want to add projectors to a hub on an Ethernet network. See
		2.6, Connecting Multiple Projectors for full routing details.
		NOTE: Refer back to 3.6, Adjusting System Parameters and Advanced Controls for
		complete information about communicating with multiple projectors.
	Matching Colors f In a multiple-projector wall, you will likely want to precisely match color and intensity
	In Multiple Screens	from image-to-image so that the full wall is as uniform as possible. This matching is
		typically done in conjunction with brightness uniformity and edge blending.
		Preliminary Calibration
		As a final part of the manufacturing process, all primary colors in the projector are
		precisely set to pre-established values to ensure that overall color performance is
		optimized and is as accurate as possible (refer back to Figure 3.21). Upon installation
		at a site, however, lighting and other environmental factors may slightly change how
		these colors appear on your screen. While the change is negligible in most cases, you
		may prefer to recover the originally intended color performance before trying to
		match colors from several projectors. Or you may be renting a projector in which the
		colors were corrected for use at its previous site, but are not ideal for yours.
		The recommended first step in achieving such consistency is to use a color meter to
		measure the native primary colors—red, green, blue, and white—as they appear at the
		screen and record these as Color Primary Settings in the Service menu (password-
		protected) for each projector. On the basis of these new values, which are stored in
		memory, each projector will then automatically calculate any necessary corrections to
		reproduce the original factory colors under the current environmental conditions. This
		essentially calibrates a projector to its surroundings, compensating for factors such as
		screen type, lamp and/or ambient lighting that can alter the final color characteristics
		on-screen, and will improve 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.
		To return to the factory-set color primaries, such as when a projector is moved to
		different site, you must access the Service menu (password-protected). Select the
		Reset to Factory Defaults? option in the Color Primaries submenu. Then repeat the
		calibration process describe above, if desired, and continue with matching of colors.
