Connecting to a Computer

18

CAUTION

When connecting the projector to a computer, be sure to check the following.

•Turn off the power for both the projector and the computer before connecting them. If the power for either device is on at the time of connection, damage may result.

•Check the shapes of the cable connectors and the device ports before making the connections. If you try to force a connector to fit a device port with a different shape or number of terminals, damage to the connector or port may result.

•Do not bind the power cable and the connecting cable together. If the power cable and the connecting cable are bound together, image interference or errors in operation may result.

Eligible Computers

The projector cannot be connected to some types of computer, or projection of images may not be possible even if actual connection is possible. Make sure that the computer you intend to use satisfies the conditions given below.

•Condition 1: The computer must have an image signal output port.

Check that the computer has a port such as an "RGB port", "monitor port" or "CRT port" which can output image signals.

If the computer has a built-in monitor, or if using a laptop computer, it may not be possible to connect the computer to the projector, or alternatively you may need to purchase a separate external output port. Refer to the documentation for your computer under a heading such as "Connecting an external monitor" or similar for further details.

•Condition 2: The display resolution and frequency of the computer must be listed in the "List of Supported Monitor Displays". s"Appendices: List of Supported Monitor Displays" p.99.

Some computers allow you to change the output resolution, so if necessary, change the resolution to one that matches a setting in the "List of Supported Monitor Displays", while referring to the documentation provided with the computer.

TIP

•You may need to purchase a separate adapter depending on the shape of the computer's port. Refer to the documentation provided with the computer for further details.

•If the computer and projector are too far away from each other for the accessory computer cable to reach, use the optional VGA-HD15 PC cable. s"Appendices: Optional Accessories" p.93
