Question: how to hook up second monitor to macbook pro?
Answer: If you are using a 2015 or older MacBook Pro, you can connect an HDMI cable from your computer directly to a monitor. If you own a new MacBook Pro with USB C or a 12-inch MacBook you will need a USB C to HDMI or USB C to DisplayPort adapter. The MacBook Air requires a mini DisplayPort to HDMI adapter.
