How to Connect a MacBook to an Optoma Projector Using USB

Many Optoma projectors come with USB functionality so that you can plug your computer into the projector directly via USB cable and run presentations from your computer. Though the projectors can also be used without a computer, when giving a presentation to a large group such as employees, business partners or possible clients, it can be very convenient to show documents and presentations that are saved on your computer. To connect your MacBook laptop to the Optoma projector you will need to plug the USB cable that came with the projector into both laptop and projector.

Open the presentation that you want to project on your MacBook so that you will be ready to project it once you have connected the laptop to the projector.

Locate the mini USB port on the back of your projector. It will be marked with the USB symbol.

Plug mini-USB end -- the small end -- of the USB cable into the mini-USB port.

Locate the USB port on the left side of your MacBook. It will have the USB symbol at its top left corner.

Plug the larger, regular USB end of the USB cable into your MacBook's USB port to connect your MacBook to the Optoma projector. Press the power button on the projector to turn it on and begin sharing the presentation from your MacBook.
