Check whether you need an adapter
Mac computers that have any of the following ports can connect to HDMI devices:
- If your Mac has an HDMI port, you can connect directly to HDMI with an HDMI cable.
- If your Mac has USB-C ports, you can connect to HDMI with an adapter, such as the Apple USB-C Digital AV Multiport Adapter.
- If your Mac has Mini DisplayPort, you can connect to HDMI with a Mini DisplayPort to HDMI adapter or cable.
Mac computers that have a built-in HDMI port comply with HDMI 1.4 or later and support:
- Up to 4K at 60 Hz on compatible Mac models.
- Up to 4K at 30 Hz on compatible Mac models.
- 8-channel/24-bit audio at 192 kHz, Dolby Surround 5.1 and traditional stereo.
- HDCP-encrypted playback from iTunes and QuickTime Player (version 10). Safari in macOS Sierra or later also supports HDCP-encrypted playback, if the web page is HTML5-enabled and the content is FairPlay Streaming-enabled and delivered using Media Source Extensions or HTTP Live Streaming. To play HDCP content on an external display, HDCP playback requires an HDCP-compatible display.
- HDR on compatible Mac models.
If using an adapter, check the specifications of the adapter to find out about supported resolutions and other details.

If your display isn't recognised
If your Mac doesn't recognise your HDTV, display or other HDMI device after making the connection:
- Turn off the HDMI device while your Mac is turned on.
- Unplug the HDMI cable from your Mac, then plug it in again.
- Turn on the HDMI device.
If your display isn't showing the whole picture
If the video on your HDTV or display extends beyond the borders of the screen, press Option-F1 on your keyboard to open Displays preferences, then adjust the Underscan slider* for a better fit.
If your Mac goes to sleep while a video is playing or paused, you may see an HDCP error. Close the app that is playing the video, then open the app again. If the issue continues, choose Apple menu > System Preferences, then click Energy Saver and adjust the settings so that your display doesn't turn off.
* The Underscan slider only appears for some configurations and resolutions.
If your HDMI device isn't receiving audio
If your HDMI device isn't receiving audio from your Mac:
- Choose Apple menu > System Preferences, then click Sound. In the Output pane, make sure your HDMI device is selected.
- If you're connecting using a Mini DisplayPort adapter, make sure your Mac can send audio over Mini DisplayPort.
- If you're connecting from a Mac mini, unplug any audio device that is plugged into your computer's Audio-Out port.
Mac computers don't support using CEC (Consumer Electronics Control) to control HDMI devices.
