Depending on models, your computer might have a Mini DisplayPort connector, a digital display interface for
connecting to various external devices, such as a CRT monitor, projector, or high-denition television. You
also can use it to connect to a DVI, VGA, or HDMI connector through a converter cable. The Mini DisplayPort
connector of your computer supports audio as well as video streaming.
1Thunderbolt 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-denition 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.

right indicator blinks yellow.
