Connect one or more external displays with your Mac
Depending on the capabilities of your Mac, you may be able to connect multiple displays. You may want to do this to make it easier to work in multiple programmes, switch between the things you’re working on or just have more screen space.
Before you begin
Before you can connect your Mac to a display, you need to determine a few things:
What kind of video ports your Mac has.
How many displays your Mac can support.
Whether or not you have the right cables.
With this information, you can connect your displays to your Mac.
Step 1: Identify the video ports on your Mac
Before you can connect displays, you need to know what type of video ports your Mac has. The ports you have determine what kind and how many external displays you can connect, and how you connect them.
Use the table below to determine what video ports your Mac has.
Note: There may be an identifying icon near each video port, depending on your Mac. If there isn’t an icon, you can still find out which ports you have. See the Apple Support article Identify the ports on your Mac.
What it looks like | Icon | Type of port |
|---|---|---|
No icon | USB-C | |
Thunderbolt 3 (USB-C), Thunderbolt / USB 4, Thunderbolt 4 (USB-C) and Thunderbolt 5 (USB-C) | ||
Thunderbolt and Thunderbolt 2 | ||
Mini DisplayPort | ||
HDMI |
For more information, see Use the ports on your Mac.
Step 2: See how many displays your Mac supports
Next, you need to determine whether your Mac supports the number of displays you want to connect.
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
: You can connect up to two displays. A DisplayPort device must be the last device in a chain of connected Thunderbolt devices.
For Mac computers with Thunderbolt or Thunderbolt 2
For Mac computers with Thunderbolt 4 (USB-C) or Thunderbolt 5 (USB-C)

Step 3: Make sure you have the right cables and adapters
If your displays come with cables that match the ports you want to use on your Mac, you can use those cables to connect the display to your Mac.
If your displays don’t have cables, obtain cables that fit the available ports on your Mac and displays.
If you have display cables, but their connectors don’t match the ports you want to use on your Mac, you may be able to use an adapter.
See the Apple Support article Adapters for the Thunderbolt or USB-C port on your Mac to identify what type of adapter you need, see what it looks like and learn what it can be used for.
Step 4: Connect your displays to your Mac
Connect your displays to your Mac using the identified video ports, cables and adapters (if needed).
After your displays are connected, you may want to adjust their settings. Choose Apple menu
If you have a third-party display, check the documentation that came with the display to get more information on the display’s video ports and cables, and to make sure you’re connecting the display according to the manufacturer’s guidelines.
