You can connect HDTVs, displays, or other HDMI devices to Mac computers using a cable or HDMI adapter.
HDMI devices can be connected to Mac computers equipped with any of the following ports. For information on determining the type of port on a Mac, see this article.
- HDMI Port: You can connect HDMI devices directly using an HDMI cable.
- USB-C or Thunderbolt 3 (USB-C) port: You can connect HDMI devices using an adapter, such as the Apple USB-C Multiport Digital AV Adapter.
- Mini DisplayPort Port: You can connect HDMI devices using a third-party adapter or Mini DisplayPort / HDMI cable.
Mac computers equipped with an HDMI port support the HDMI 1.4b standard and the following features.
- Transfer via HDMI video with a resolution of at least 1080p. Some Mac models support higher resolution transmission when connecting 4K, 5K displays and Ultra HD TVs.
- Transmission of 8-channel 24-bit audio with a sampling frequency of 192 kHz in Dolby Surround 5.1 mode and in traditional stereo format.
- Play files from iTunes and QuickTime Player (version 10) with HDCP encryption. Safari on macOS Sierra or later also supports HDCP encrypted playback if the webpage was created using HTML5 and the content was created using FairPlay Streaming, while the transfer is from Medisource Extensions or HTTP Live Streaming.
When using an adapter, review its specifications to find supported resolutions and other data.
If your Mac does not recognize a connected HDTV, display, or other connected HDMI device, follow these steps:

If the image on the HDTV or display goes beyond the screen, open the “Monitors” settings section and adjust the image size using the “Compressed Scan” slider. The “Monitors” settings section can be opened in one of the following ways.
- Go to the Apple menu () > “System Preferences” and select “Monitors”.
- Press Shift Command A to open the Programs folder. Then double-click System Preferences and select the Monitors option.
- If your keyboard has brightness controls, press Option “Increase Brightness” or Option “Decrease Brightness”.
If you don’t get audio from your Mac on your HDMI device, follow these steps:
- Go to the Apple menu > “System Preferences” and select “Sound”. Verify that the HDMI device is selected in the Output panel.
- If your device is connected via a Mini DisplayPort adapter, make sure your Mac supports audio through Mini DisplayPort.
- When connecting your device to Mac mini, disconnect all audio devices from the audio output port.
If the Mac goes into sleep mode while playing a video or while it is paused, an HDCP error message may appear. Close the program in which the video is playing and open it again. If the problem persists, go to the Apple menu > “System Settings,” select “Power Saver,” and adjust the settings so that the display does not turn off.
- If your Mac is equipped with an HDMI port, you can connect the DVI display using the Apple HDMI / DVI adapter.
- Mac computers do not support the HDMI device control function called CEC (Consumer Electronics Control).
