Mac supports multiple monitors depending on the model and interface type. The M1/M2 series MacBook Air and 13-inch MacBook Pro support up to one external monitor, and the 14-inch and 16-inch MacBook Pro supports two or three. Mac mini, iMac, and Mac Studio usually support at least two. You can view specific specifications through the official website or "About this machine". The connection methods include USB-C to HDMI direct connection, multi-port dock split screen, and Thunderbolt tandem connection (requires monitor support). When purchasing docking dock, you need to confirm the resolution and refresh rate compatibility; in system settings, go to "System Settings" → "Display" to adjust the screen arrangement, mirror mode, expand the desktop and resolution. If the monitor does not respond, check the cable, interface and power supply.

It is actually not difficult to connect multiple monitors to a Mac. The key is to figure out which interface you are using, how many screens the Mac model supports, and how to set it up. As long as the hardware matches, the system will be set up very quickly.

Check how many external monitors your Mac supports

Different models of Mac support different external screens, such as:

• M1/M2 series MacBook Air and 13-inch MacBook Pro : supports up to one external monitor
• 14-inch and 16-inch MacBook Pro (M1/M2) : Supports up to two or three external monitors (details depending on the version)
• Mac mini, iMac, Mac Studio : usually supports at least two external monitors

You can check the specific support status of your machine on the product page of Apple's official website or in the technical specifications in "About this machine".

The interface type determines how you wire it

Now the new Macs are basically Thunderbolt/USB-C interfaces, and the older ones may be HDMI or Mini DisplayPort. Common connection methods include:

• Direct connection using USB-C to HDMI cable
• Use a multi-port dock to separate multiple monitor signals
• Daisy chain connection method connects multiple monitors (provided that the monitor supports it)

Note: Although some docks have multiple video output ports, they may not necessarily support multiple high-resolution screens at the same time. Before buying, you must confirm whether they support the resolution and refresh rate you need (for example, 4K@60Hz).

It's easy to set up dual-screen or multi-screen displays on macOS

After plugging in the cable, enter "System Settings" → "Display" and you will see all the connected screens. you can:

• Drag the screen icon to adjust the arrangement order so that the mouse moves
• Click each screen to select whether to enable mirror mode or expand the desktop
• Set different resolutions for different screens

If a monitor does not respond, first check whether the cable and interface are plugged in tightly, and then check if the power supply is insufficient (especially when connected through the dock).

Basically that's it. Select the right cable, confirm the number of supported, and then simply adjust the system settings, and multiple monitors can be used.
