Can a MacBook Air support 2 monitors?

MacBook Air with M4 or M5 runs two external displays with the lid open. With M3 it runs two only with the lid closed. MacBook Air with M1 or M2 supports one.

Can a MacBook Air support 2 monitors with a docking station?

A dock doesn't raise the chip's limit, so an M1 or M2 MacBook Air still drives one display natively. DisplayLink docks add more screens through a driver.

How many monitors can a MacBook Pro support?

Two with M4, M4 Pro, M5, M1 Pro, M2 Pro or M3 Pro, three with M5 Pro, and four with any Max chip. The 13-inch M1 and M2 models support one, and the 14-inch M3 supports two with the lid closed.

Why do both monitors show the same thing on my MacBook?

Usually the hub mirrors one video signal to both ports, or the Mac's chip supports only one external display. Connect a display directly to the Mac, or check Use as in System Settings, Displays.

Can I use two monitors with my MacBook lid open?

Yes on M4 and M5 models and on Pro and Max chips. MacBook Air and the 14-inch MacBook Pro with M3 need the lid closed for the second display.

How to set up two external monitors on a MacBook

By Aqib Javed · Updated Nov 2, 2026

Whether a MacBook can run two external monitors depends on its chip. MacBook Air and MacBook Pro with M4 or M5, and MacBook Pro with M1 Pro or later Pro and Max chips, run two or more with the lid open. MacBook Air and the 14-inch MacBook Pro with M3 run two only with the lid closed. MacBook Air with M1 or M2, and the 13-inch MacBook Pro with M1 or M2, support one. Then arrange both screens in System Settings, Displays, Arrange.

How many external displays each MacBook supports

MacBook Air with M1 or M2: one external display.
MacBook Air with M3: one with the lid open, two with the lid closed (macOS Sonoma 14.3 or later).
MacBook Air with M4 or M5: two, in addition to the built-in display.
MacBook Pro 13-inch with M1 or M2: one.
MacBook Pro 14-inch with M3: two with the lid closed (macOS Sonoma 14.6 or later).
MacBook Pro with M4, M4 Pro or M5: two.
MacBook Pro with M1 Pro, M2 Pro or M3 Pro: two.
MacBook Pro with M5 Pro: three.
MacBook Pro with M1 Max, M2 Max, M3 Max, M4 Max or M5 Max: four.

These are Apple's numbers from its tech specs and its How many displays can be connected pages. Resolution limits apply too: with two displays, many models top out at 6K at 60Hz or 4K at 144Hz each. To check your own Mac, choose Apple menu, About This Mac to see the chip, then look up its tech specs on Apple's site under Display Support.

The lid-closed trick for M3 MacBooks

Connect an external keyboard and a mouse or trackpad.
Connect the Mac to power, or use a display that powers the Mac over USB-C.
Connect the first display. It becomes the main display.
Close the lid.
Connect the second display.

Apple notes that opening the lid with both displays connected can turn the second display dark. On M4 and M5 models you don't need this: they run two displays with the lid open, and closing it doesn't add a third.

Cables, hubs and docks

Connecting each monitor straight to a Thunderbolt or USB-C port on the Mac, or to the HDMI port on models that have one, is the most reliable setup.
A Thunderbolt dock can carry two displays over one cable, but Apple says hubs and daisy-chaining never raise the chip's maximum.
Many cheap USB-C hubs with two HDMI ports show the same picture on both screens on a Mac. If that happens, Apple's advice is to connect a display directly to the Mac.
DisplayLink docks use a driver to add screens beyond the chip's limit. They work for documents and code, but they rely on the DisplayLink Manager app running, so test before you buy.

How to arrange both screens

Open System Settings, then Displays, and click Arrange.
Drag the screens to match where they sit on your desk, so the pointer crosses at the right edges.
Drag the white menu bar onto the screen you want as the main display. The Dock and new windows of many apps start there.
Click Done. To mirror one screen instead, choose it in Displays and change Use as.

Keeping windows on the right screen

Two monitors means more windows landing in the wrong place after you dock, wake or unplug, and macOS can swap identical monitors around. DisplayShift works with two or more external displays: when a display connects it lists every open window and moves the ones you tick, you can choose which display they go to, and layouts are remembered for each combination of screens. Keep my screen arrangement (Settings, Screens) puts your arrangement and main display back if macOS swaps them after a plug-in or wake. Tile up to six apps on one screen with Control Option Command T. It's free for 7 days, then $6.99 once.
