Relaying information to a large audience is challenging. From passing out notes to using an overhead projector, there are a variety of tools you can use to try to make the information clear to your audience. One way you can relay information to your audience is by creating a presentation on your laptop and displaying it with your Optoma projector. To connect a Optoma projector to your laptop, you don't need to hire an audio/video specialist or install any additional software on your laptop. The Optoma projector includes a cable to make the connection possible.
Turn off your laptop computer, if it is on.
Plug one end of a VGA cable into the "VGA" port on the back of the Optoma projector. The VGA cable is included with the Optoma projector.
Plug the other end of the VGA cable into the "VGA" port on the side or back of your laptop. If using a Mac, plug the other end of the VGA cable into the "VGA" port on the side of a DVI to VGA adaptor. Plug a DVI cable into the "DVI" port on the other side of the DVI to VGA adaptor. Plug the other end of the DVI cable into the "DVI" port on the back or side of your Mac laptop.
Plug one end of a 1/8-inch audio cable into the "Audio" port on the back of the Optoma projector.
Plug the other end of the 1/8-inch audio cable into the "Audio" or "Headphone" port on the back or side of your laptop.
Turn on the Optoma projector by pressing the "Power" button on the projector. The projector will take about a minute to start up.
Turn on your laptop. Your computer may auto-detect the projector. You will see your laptop's display projected through the Optoma projector. If you don't see your laptop's display, press the function key on your laptop's keyboard that activates the VGA port on your laptop. Consult with your laptop's manual for more information.
Use the "Audio" buttons on the Optoma projector to adjust the audio transmitted from your laptop.
To adjust the projected image, move the cart the Optoma projector is sitting on. To turn off your Optoma projector, press the "Power" button twice. Wait until the cooling fan stops before unplugging the projector.
