If you’re not sure how many external displays your Mac mini supports, check your Technical Specifications. Open System Settings, choose Help > Mac mini Specifications, then locate Video Support (you may need to scroll).

Note: When connecting multiple displays, connect the display with the highest resolution first.

To learn more about using an 8K display with your Mac mini, see the Apple Support article Use an 8K display with your Mac .

Tip: If you have a high resolution TV connected to an Apple TV, you can use AirPlay to mirror your screen. See Use AirPlay on your Mac for details.

If your display has a connector that doesn’t match the port you want to use, you may be able to use it with an adapter (sold separately). Visit apple.com, your local Apple Store, or other resellers for more information and availability. Review the display’s documentation or check with the display’s manufacturer to make sure you choose the right product. See the Apple Support article Adapters for the Thunderbolt 4, Thunderbolt 3, or USB-C port on your Mac.
