The easiest way to connect a non-Apple monitor to a Mac laptop that doesn’t feature an HDMI port is to use an adapter that converts HDMI to Mini DisplayPort or Thunderbolt, depending on your machine. Most Macbook Pro laptops feature Thunderbolt 2 or 3 ports, along with a couple of USB ports.

The easiest way to connect a non-Apple monitor to your Mac is by using an HDMI cable because most Mac laptops and non-Apple monitors come equipped with such ports.

If these methods don’t work on your laptop, you will need to revert to connecting your second Apple monitor just like any other non-Apple one. Once you’ve connected it, turn on both devices, and your laptop should recognize the second monitor automatically. After locating the ports, take the cable from your second monitor and plug it into the appropriate port.
