Within the Displays settings, you can choose to “Mirror Displays” to show the same content on both screens, or “Extend Display” to create a larger workspace. You can also arrange the positioning of your displays by dragging their representations in the settings window, allowing you to control which side your external monitor is on relative to your MacBook’s screen.
Can I connect multiple external displays to my MacBook?
The ability to connect multiple external displays depends on your MacBook model and its specifications. Newer MacBooks with Thunderbolt 4 ports generally support multiple external displays, often with higher resolutions and refresh rates. However, older models or those with fewer Thunderbolt ports might have limitations on the number and type of displays they can support simultaneously.
To connect multiple displays, you’ll likely need a Thunderbolt dock or a USB-C hub that offers multiple display outputs (e.g., two HDMI ports, or an HDMI and a DisplayPort). Always check the specifications of your MacBook and the dock/hub to ensure compatibility and to understand the maximum supported resolutions and refresh rates for each connected display.
What should I do if my MacBook isn’t detecting the external display?
First, ensure all cables are securely connected at both ends – your MacBook and the external display. Try using a different, known-good cable or adapter, as faulty cables are a common cause of connection issues. Also, confirm that the external display is powered on and set to the correct input source that matches the port you’re using (e.g., HDMI 1, DisplayPort).
If the connection is still not recognized, restart your MacBook. Sometimes a simple reboot can resolve temporary software glitches preventing detection. You can also try disconnecting and reconnecting the display cable. If you’re using a USB-C hub or dock, try connecting the display directly to your MacBook using a different adapter to rule out the hub as the problem.
How can I adjust the resolution and refresh rate of my external display?
After connecting and enabling your external display through the “Displays” settings in System Settings/Preferences, you can adjust its resolution and refresh rate. Select your external display from the list of detected monitors. Under the resolution options, you can choose between “Default for display” or “Scaled.” The scaled option allows you to select various resolutions, which can make text and icons appear larger or smaller.
For refresh rate, you’ll typically find a dropdown menu next to “Refresh Rate.” Select the highest available refresh rate that your display supports for smoother motion. It’s important to note that not all displays offer a wide range of refresh rate options, and the available choices will also be influenced by the capabilities of your MacBook and the connection type being used.

Mirroring your display means that the content shown on your MacBook’s screen will be exactly duplicated on the external display. This is useful for presentations or when you want to share what you’re doing with others. Both screens will show the same resolution and orientation, and whatever you do on one screen will immediately appear on the other.
Extending your display treats the external monitor as a separate workspace, effectively giving you more screen real estate. This allows you to drag windows between your MacBook and the external display, running different applications on each screen simultaneously. This is ideal for multitasking, improving productivity by having multiple documents or programs open and accessible at once.
Can I use a wireless display adapter with my MacBook?
Yes, you can connect to wireless displays or cast your MacBook’s screen wirelessly, primarily through technologies like AirPlay. If your external display or a connected streaming device (like an Apple TV) supports AirPlay, you can use the Screen Mirroring option in your Mac’s Control Center or Menu Bar to wirelessly send your display output.
AirPlay is most effective when your MacBook and the receiving device are on the same Wi-Fi network. While convenient for casual use or presentations, wireless connections can sometimes introduce slight latency or a reduction in video quality compared to a direct wired connection. For demanding tasks like high-refresh-rate gaming or precise video editing, a wired connection is generally recommended.
