M1 Mac cannot connect more than 2 monitors

By default, a Mac can have multiple monitors connected to it. However Macs with M1 chips have only one external display.can only connect

For Mac computers with the Apple M1 chip: You can connect one external display to your Mac. The Dock cannot increase the number of displays it can connect to. On Mac mini with M1 chip, you can connect a secondary display to the HDMI port.


This is because Macs with M1 chip support only one external monitor display.




Connecting 1 monitors to M2 Mac

The M1 MacBook cannot connect more than two monitors, but there are adapters and software that make this possible.


How to connect two or more monitors in M1 Mac

If Apple, the maker, doesn't do it, a third party makes it possible. I found that there is still a way.

The principle is simple. Mirror the display with software, and send the mirrored screen to the monitor through a USB adapter.

Depending on the adapter, multiple monitors can be connected.



USB to HDMI adapter


I found a few.



Ali HDMI to VGA Adapter

I don't need 4K, the cheapest aliexpress HDMI VGA adapter bought

There are USB 3.0, USB 2.0, wired Internet, VGA, and HDMI ports.


The M1 MacBook Air has only two USB-C ports and does not have a USB-A port, so when connecting an external hard drive or USB memory sometimes, a converting adapter is used, but these days this adapter is used.


Features and specifications are as follows.

• USB Specification-3.0
• Supports maximum video resolution - 2048 1152
• Supported Operating Systems - Windows XP, Vista (32 & 64bit), 7 (32 & 64bit), 10, or Mac
• Power Mode - Bus Powered

• Display and device ports: 1x HDMI, 1x VGA.
• Network Connection: 1x RJ-45 Ethernet port.
• Main chip: DL-3700


You can connect this adapter directly to the USB-C of the M1 MacBook Air, and there is a jack for connecting to USB-A.





The default cable of the adapter is USB-C, so it can be connected directly to the M1 MacBook Air.




I want to connect a monitor Apple Multiport Adapter, connect it to the USB-A of the Apple adapter and connect it to the supplied jack.




DisplayLink app

You have to connect the monitor to the USB-HDMI adapter in hardware and send the screen to this monitor in software.

An app that makes this possible is a program called DisplayLink.

Up to 6 monitors are possible.


Installing and setting up DisplayLink

All you have to do is install it on your Mac and check Enable Screen Recording.

  1. Download DisplayLink driverand install it
  2. In Mac's System Preferences, go to Security & Privacy > Privacy > Screen History and check DisplayLink Check to open the lock screen with Apple Watch.
  3. Click the DisplayLink icon on the menu bar (the shape of two monitors overlapping each other) and check to be automatically launched when logging in.


When the monitor is connected to the adapter, another screen is displayed.



CPU occupancy and heat are almost nonexistent

Since the software is mirroring, I checked whether there is CPU usage and heat, but there is no effect on CPU occupation or heat generation. thank God.




Now I have one more monitor. I knew it The size of the monitor has an effect on productivitythere is The main screen used is the monitor on the front of the MacBook, and the secondary screen is placed on the left.

It's annoying to turn my head, but my eyes are bad, so I can't use a high-resolution monitor without glasses. I think it's better to use two low-resolution monitors. Monitors are cheap too.




The picture below is my desk in 2003 with a 17-inch monitor connected to my MacBook.

is a feeling of exasperation.
You can also see the PDA phone, Alyuki. 😆
