Apple has a helpful guide on their website. The projector won’t know the difference – and all the HDCP copy protection and image quality enhancements such as resolution scaling will work to make any Mac look good on the screen. If you have an HDMI equipped projector, you can use simple adapters on the cable to convert the HDMI signal to the right physical form to connect to your laptop.
