You can connect most PCs to a projector in just a few simple steps using an external VGA or HDMI cable.

VGA is one of the most common input types for digital projectors. If your projector and your laptop are both equipped with VGA ports, you can connect them with a VGA cable.

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.
