Connect one or more external displays with your Mac
You may be able to connect one or more external displays to your Mac (you may need a video cable or adapter for each display). See the Apple Support article Adapters for the Thunderbolt 4, Thunderbolt 3 or USB-C port.
Connect the displays wirelessly
You can wirelessly connect your Mac to devices, such as another Mac and certain smart TVs, and use them as displays.
Choose Apple menu
in the sidebar. (You may need to scroll down.) Click the
pop-up menu on the right (below the name of your Mac), then choose your display.
Connect the displays with a cable
For each display, securely connect a video cable (and adapter, if necessary) from a video output port on your Mac to the video input port on the display. See About the video ports.
You can connect one or more external displays, depending on your Mac.
For Mac computers with the Apple M1 Chip: You can connect a single external display to your Mac. Docks don’t increase the number of displays you can connect. On a Mac mini with M1 chip, you can connect a second display to the HDMI port. See the Apple Support article Mac computers with Apple silicon.
For Mac computers with Thunderbolt 3 (USB-C): You can connect a single display to each port. If you connect multiple Thunderbolt devices to each other, the Thunderbolt 3 display must be the last device in the chain. If your Thunderbolt 3 display has USB ports, those can be used for data and power.
For Mac computers with Mini DisplayPort, Thunderbolt or Thunderbolt 2: You can connect up to two displays. If the displays themselves have Thunderbolt ports, you can connect one display to another and then connect one of the displays to a Thunderbolt port on your Mac. If your Mac has two Thunderbolt ports, you can connect each display to separate Thunderbolt ports on your Mac. A DisplayPort device must be the last device in a chain of connected Thunderbolt devices. See Connect a display, TV or projector to Mac.
For Mac computers with Thunderbolt 4 (USB-C) and HDMI ports: You can connect up to four external displays to your Mac, depending on your Mac model. See the Apple Support article Connect a display to your Mac.
Note: Only the device directly connected to your Mac receives power from the computer’s Thunderbolt port. The other devices in the chain must be powered by separate power adapters.
