Using the Mini DisplayPort connector

Depending on the model, your computer might have a Mini DisplayPort connector, a digital display interface for connecting various external devices, such as CRT monitors, LCD monitors, projectors, or even high-definition televisions. This connector enables a plug-and-play setup and supports adapters that can plug into DVI, VGA, or HDMI connectors.

The Mini DisplayPort connector of your computer supports audio as well as video streaming.

Note: Use DisplayPort certified cable with DisplayPort icon () to connect the device for stable functionality.

Using the Thunderbolt connector

Depending on the model, your computer might have a Thunderbolt connector. It enables you to connect your computer to a Thunderbolt compatible device or a Mini DisplayPort compatible device, such as CRT monitors, LCD monitors, projectors, or high-definition televisions. The Thunderbolt connector has the same appearance as the Mini DisplayPort connector other than the icon. If you connect a Mini DisplayPort compatible device to the Thunderbolt connector, it generates Mini DisplayPort signals automatically.
