It's easy to connect an iPad to a projector to stream content to a larger display. Here's what you need to know to do it.

Connect one end of the USB cable to the USB port on the back of your Optoma projector, and then connect the other end of the cable to an available USB port on your MacBook.

The Apple USB-C VGA Multiport Adapter lets you mirror your Mac display to a VGA-enabled projector, TV or display in up to 1080p HD. Thankfully there are cheaper third-party USB-C to VGA adapters.
