Add an external monitor to your computer via a video port.
The type of port available depends on your computer's
configuration.

Connecting a monitor

1. Check that the computer is powered off and the monitor
power switch is turned off.
2. Attach the video cable to the monitor port on the computer.
3. Connect the monitor power cable and plug it into a
properly grounded wall outlet.
4. Follow any setup instructions in the monitor's user's guide.
5. Turn on power to the monitor, then the computer.
6. The correct resolution and refresh rate should be
detected automatically. If necessary, change the display
settings used by the computer.
Note
To access the display controls, right-click anywhere on the
desktop and select Display settings.

Headphones and microphone

One or more 3.5 mm jacks on your computer allow you to
connect audio devices.
Use the headphone port to plug in stereo headphones or
powered speakers; connecting an audio device to the
headphone port disables the built-in speakers.
Use the microphone port to connect an external microphone;
connecting a microphone disables the built-in microphone.
Note
Some computers have a single "combo" port that allows you to use
single-pin headsets with a built-in microphone. These headsets are
most commonly used with smartphones.
