Using multiple

projectors

When working with more than two projectors, work left to right, top to bottom.

When an installation requires multiple projectors, use the RS232 serial ports to daisy chain the units

together and control the group with a single keypad or a 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. For additional

information, refer to M Series Installation and Setup Guide (P/N: 020-101941-XX)

Image tiling allows a single input image to be displayed, spread over multiple screens, with each

screen displaying a fraction of the image.

The image is displayed by the m × n array of projectors, where m is the number of rows (1-3) and n

is the number of columns (1-3). This allows the following arrays to be set up:

1x2, 2x1, 1x3, 3x1, 2x2, 2x3, 3x2, 3x3

Projectors are numbered from left to right (left column = 1), and from top to bottom (Top row = 1).

1. Set the total number of rows and columns in the array.

This setting is the same on all the projectors in the array.

2. Set the relative location of the projector within the array by identifying the row number and

column number for each projector.

3. Enable Tiling.

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.

Lighting and other environmental factors may slightly change how these colors appear on the 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.
