Using the video features
Using the external monitor port
The external monitor port connects an external display device, such as an external monitor or a projector,
to the computer.
▲
To connect a display device, connect the device cable to the external monitor port.
NOTE:
If a properly connected external display device does not display an image, press
fn+f4
to
transfer the image to the device. Repeatedly pressing
fn+f4
alternates the screen image between the
computer display, the device, and simultaneous display on both the computer display and the device.
Using the HDMI port
The High Definition Multimedia Interface (HDMI) port connects the computer to an optional video or
audio device, such as a high-definition television, or any compatible digital or audio component.
The computer can support one HDMI device connected to the HDMI port, while simultaneously
supporting an image on the computer display or any other supported external display.
NOTE:
To transmit video signals through the HDMI port, you need an HDMI cable (purchased
separately), available from most electronics retailers.
