High-Definition Multimedia Interface (only for certain models)
HDMI (High-Definition Multimedia Interface) is an industry-
supported, uncompressed, all-digital audio/video interface.
HDMI provides an interface between any compatible digital
audio/video source, such as a set-top box, DVD player, and
A/V receiver and a compatible digital audio and/or video
monitor, such as a digital television (DTV), over a single
cable.
Use the HDMI port on your computer to connect with high-
end audio and video equipment. Single cable
implementation allows tidy setup and fast connection.
Headphones and microphone
These two ports allow you to connect audio devices. Use the headphone
port to plug in stereo headphones or powered speakers. Plugging an
audio device to the headphone port disables the built-in speakers. Use the
microphone port to connect an external microphone for mono recording;
plugging in an external microphone disables the built-in microphone.
