Connecting an external display to your Mac can significantly enhance your productivity and viewing experience. Whether you’re a professional looking to extend your workstation or a gamer seeking an immersive experience, using an external monitor can be highly beneficial. However, the process of setting up an external display can sometimes be confusing, especially for those who are new to Macs. In this article, we’ll delve into the details of how to allow external displays on your Mac, exploring the various connections, settings, and troubleshooting tips you might need.
Understanding Mac Display Ports and Connections
Before you start connecting your external display, it’s essential to understand the types of ports and connections your Mac supports. Apple has transitioned through several types of display ports over the years, including VGA, DVI, HDMI, DisplayPort, and the more recent USB-C/Thunderbolt 3 ports.
Identifying Your Mac’s Ports
The first step is to identify the ports available on your Mac. For newer Mac models, especially those from 2015 onwards, you’re likely to find Thunderbolt 3 (USB-C) ports. Older models might have a mix of HDMI, DisplayPort, and older Thunderbolt ports. Knowing your Mac’s ports is crucial because it determines the type of adapter or cable you’ll need to connect your external display.
Adapters and Cables for External Displays
If your Mac and external display don’t share a common port type, you’ll need an adapter or a specific cable to make the connection. For example, if your Mac only has USB-C ports but your display uses HDMI, you’ll need a USB-C to HDMI adapter. Apple and third-party manufacturers offer a variety of adapters and cables that can help you connect your display to your Mac, regardless of the port types.
Setting Up Your External Display
Once you have the right adapter or cable, setting up your external display is relatively straightforward. Here’s a step-by-step guide:

Mirroring vs. Extending Your Desktop
You have two main options for using your external display: mirroring and extending your desktop. Mirroring will show the same content on both your Mac’s screen and the external display. This is useful for presentations. Extending your desktop allows you to have different windows and applications open on each screen, greatly increasing your workspace. You can drag windows from your Mac to the external display and vice versa.
Troubleshooting Common Issues
Sometimes, despite having the right connections and settings, your external display might not work as expected. Here are some common issues and their solutions:
