How to Set Up Your Projector on a Network
By James T Wood
Some projectors come with the ability to connect to a local area network, thereby allowing you to not have to plug in a video cable to use the projector. Because network connections aren't as fast as the direct connections from a video cable, full motion video probably won't look very good, but still images and presentation slides are ideal for running on a projector via a networked computer.
Connect your projector to your local area network. If you have a cable connection, plug the Ethernet cable from the projector into a network jack or router. If you have a Wi-Fi connection, use the on-screen configuration utility on your projector to enter your Wi-Fi network name and passcode.
Note the IP address of the projector on your network. An IP address is a series of numbers separated by periods that identifies a location on a network, for example 192.168.1.1. The IP address will be available in the on-screen configuration tools for your projector. Look for Network or LAN settings.
Connect your computer to the network, either wired or wirelessly. If the projector has it, install the networking software on your computer. A CD or DVD may have come with your projector. Not all projectors have software that can be installed. If no software came with your projector, you may be able to use the built-in software on your computer to access the projector.
Power on the projector, if it isn't already. Launch the software that came with the projector. Or, alternatively, press the Windows Key, type "Connect to a Network Projector" and press Enter.
Choose your projector from the options listed. If you don't see your projector listed, you can type in the IP address of the projector. Choose the option to connect to the projector. It will appear as an additional display on your computer.
Press “Windows-P" to select the way you want the projector to function. Press "P" while holding down the Windows key until the option you want is highlighted, and then release both keys. "Duplicate" will display the same information on your computer and the projector. "Extend" will use the projector as additional display space, which is useful if you have presenter notes. "Projector Only" will not display on your computer but only on the projector.
If you can't find the IP address on the projector, open up the configuration page for your network's router and look at the devices connected to it. The projector should be listed by name -- likely a model number -- with the IP address associated with it.
