How To Extend Screens On Mac
You can extend your Mac display to another screen or mirror it to display the same content on multiple screens. To extend your display, click the “Arrangement” tab, and then make sure that the “Mirror Displays” checkbox is not selected. You can then drag the menu bar or the white rectangle on the screen to match the layout of your physical screens.
Once you figure out exactly what displays — and how many — you can plug in, just make sure that your external displays are connected to power (if needed) and plug them into the MacBook using whichever cable connections are available to you depending on which year your MacBook was made. Remember, your MacBook supports external monitors as your sole display as long as the MacBook is connected to power. Once MacBook is connected to monitors, you have the option of closing the lid so the external monitor is your only display.

| 1 | Choose Apple menu |
| 2 | Then System Settings |
| 3 | then click Displays in the sidebar. (You may need to scroll down) |
| 4 | pop-up menu on the right (below the name of your Mac) |
| 5 | Then choose your display |
If you are not looking to take advantage of the extra display real estate, and would prefer to swap out your MacBooks screen for the display, you can tick the box marked Mirror displays, so the external monitor displays exactly what you are doing on the Mac, instead of acting as an extension. Check the Mirror Displays checkbox if you would like to use the mirroring method of showing the same content across both displays. Choose Apple Menu > System Preferences > Click on Display, then choose the Adjustments tab to ensure that the Mirror Displays?checkbox is selected.
If you somehow cannot see the AirPlay icon, tap on Apple Menu on the top-right, and navigate to System Preferences > Displays, and select Show mirroring options on the menu bar if it is available.
Setup is all done in the same Displays menu, which can be accessed by clicking on the Apple icon within the Menus followed by System Preferences, and then displaying the Apple icon in the Menus followed by System Preferences, then Displays system preferences.
Alternatively, from the same Displays menu, right-click the screen on which you wish to modify its properties and select Expanded Display or Mirroring For. You can also right-click on a display to make one of them the main screen, expand a screen, or mirror another monitor. You can adjust resolutions, as well as whether you are expanding or mirroring displays, in the display settings.

If you are using an external display for watching movies, doing detailed photo or video editing, or working on a very specific task where all you need is as much real estate as possible, you may want to show a maximum resolution. For the resolution, you have a choice of showing the best resolution that your monitor has to offer, or scaling your display down to fit your laptop. If the monitor is physically on the left side of your MacBook, and you would like to stretch out your display with this configuration, be sure to take the steps outlined above to access the system settings and adjust the display accordingly.
You can configure the displays under System Settings as soon as you connect the display(s) to the computer. Connect the Pen Display to the computer, and reference the following display modes to configure additional displays on a Mac.
Do the following to show menu bars and the Dock on two monitors, and prevent the spread of the windows or application across the monitors. On Mac, click on the Display icon on the menu bar, and below the connected iPad, you should see the option Hide Sidebar and Hide Touch Bar.
When you want to show the same screen across multiple monitors, right-click on the monitor you would like to set as your primary display, and choose Mirror built-in retina display (for Retina models) from the list. If you have an iMac from 2014 or older, and your primary Mac is running macOS Catalina or older, you can use the iMac as the display using the Target display mode.
Depending on your needs, you might have to tell macOS you are going to mirror or stretch the display. When you connect your MacBook to an external display, macOS simply mirrors the screen of the MacBook to your display, rather than expanding it to create additional workspace. MacBook Airs can use one external display and its built-in display at once.
Apples silicon models, which have M1 chips, can handle two displays in a Mac mini, including a 6K display via Thunderbolt 3, and a 4K screen over HDMI. Apples lineup of MacBooks using the companys proprietary Silicon M1 or M2 processors cannot connect to more than one external display natively, a significant limitation on previous generations of Intel-based Mac notebooks, which were capable of handling two displays if connected to USB-C or Thunderbolt 3 docks or hubs.
For instance, my 16-inch MacBook Pro allows me to use the four Thunderbolt 3 ports to connect up to four 4K displays, or two 6K displays. If there is a difference in ports, like you need to use HDMI with your display, but that connection is not available on a Mac, then adapters can be used. Look for a dock that has two or more display ports, preferably one that you can plug into the display of choice without needing adapters.

You can also attach your first screen through another display port on the dock, or through a Thunderbolt or USB-C-to-HDMI or DisplayPort adapter. You can also use the USB connection for both Apple devices, which has the benefit of allowing you to charge your iPad too, when it is being used as the second display. As long as you have a compatible Mac and an iPad, you will be able to connect both Apple devices quickly and easily, and use iPad as an additional display for the Mac.
Using Sidecar, which comes built-in with supported devices, you can then extend your MacOS desktop, or simply mirror it on your iPad, complete with touch-screen controls for seamless use of both devices together.
The iPad is not strictly a display, since you get a bit more interactivity if you have the Apple Pencil, but you do get the same mirroring options, as well as more settings that you can manage in the Displays window. An Apple TV is designed to work with TVs, but can also be used to plug into HDMI-enabled computer monitors.
If you own the MacBook Air 13, you can set up one extra monitor via its own native hardware – although there is a workaround for connecting one more (see below). Apple notes that MacBooks running the Apple silicon chips are currently limited to a single external monitor connected through one of the Thunderbolt/USB 4 ports; this is a welcome feature for those wanting to hook MacBook Airs to monitors, since any port is available.
