Setting Up two monitors on Macbook M1

I'm setting up my Macbook Air M1 to run two monitors. One of the monitors (ASUS) works with no problem but I can't get the second one (LG 4k) monitor to work. I'm using a Toshiba dynadock for the LG and a Anker dongle for the ASUS. Do I need a Thunderbolt 4 cable to make it work?

MacBook Air 13″, macOS 13.0

I got both monitors to work using the Plugable dongle. So far it looks good. Thanks for the information.

I’ve looked on YouTube and two monitors hooked up to the MacBook Air M1. The videos I saw used different dongles including a Hyper 10 in 1 usb-c hub. Maybe I need go to DisplayLink and read what they have to say too.

The M1 Macs do not support multiple external displays. There are work arounds like you mention but the fact remains that the computer does not support multiple displays. Your display performance may not be what you would expect when using a work around.

Mac computers with Apple silicon

On Mac computers with Apple silicon, you can connect

up to 5 displays depending on the chip in your Mac. To find out which

chip your Mac has, choose Apple menu  > About This Mac. 


If you're using a Mac Studio with M1 Ultra:

  • You can connect up to five external displays to your Mac using the
  • Thunderbolt 4 (USB-C) and HDMI ports on the front and back of the
  • computer.


If you're using a Mac with M1 Max:

  • On MacBook Pro, you can connect up to four external displays to your Mac using the Thunderbolt 4 (USB-C) and HDMI ports.
  • On Mac Studio, you can connect up to five external displays to your
  • Mac using the Thunderbolt 4 (USB-C) and HDMI ports on the back of the
  • computer.


If you're using a Mac with M1 Pro:

  • You can connect up to two external displays to your Mac using the Thunderbolt 4 (USB-C) and HDMI ports.


If you're using a Mac with the M1 or M2 chip:

  • On MacBook Air, 13-inch MacBook Pro, iMac, and Mac mini, you can
  • connect one external display using either of the Thunderbolt / USB 4
  • ports. On iMac, connect your display to either of the ports with the
  • Thunderbolt symbol .
  • On Mac mini, you can connect a second display to the HDMI port.
  • Using docks or daisy-chaining devices doesn't increase the number of displays you can connect.
