HDMI displays

Mac computers with built-in HDMI ports

Any Mac with a built-in HDMI port can support 4K displays and Ultra HD TVs via HDMI at 3840 x 2160 at 30Hz, or 4096 x 2160 at 24Hz. Note that mirroring isn't supported at 4096 x 2160 at 24Hz.

Additionally, the built-in HDMI port on Mac mini (2018) supports resolutions up to 4096 x 2160 at 60Hz.

Mac computers compatible with HDMI via adapter

The following Mac models support resolutions and refresh rates of up to 1080p at 60Hz, and 3840 x 2160 at 30Hz, over HDMI 1.4b when using the Apple USB-C Digital AV Multiport Adapter with macOS Sierra 10.12 or later:

The computers listed above also support 60Hz refresh rate over HDMI when used with a supported HDMI 2.0 display, HDMI Premium Certified cable, and a compatible third-party USB-C to HDMI 2.0 adapter.

If the HDMI display that's connected to your Mac starts up to the Apple logo but then goes dark, you might need to update your HDMI cable. To ensure compatibility, and to achieve 4K resolution, Apple recommends a cable that supports HDMI 2.0 or later, such as the Belkin Ultra High Speed 4K HDMI Cable.
