DisplayPort (select models only)
The DisplayPort connects the computer to an optional video or audio device, such as a high-definition
television, or to any compatible digital or audio component. The DisplayPort delivers higher
performance than the VGA external monitor port and improves digital connectivity.
NOTE: To transmit video and/or audio signals through the DisplayPort, you need a DisplayPort
cable (purchased separately).
NOTE: One DisplayPort device can be connected to the DisplayPort port on the computer. The
information displayed on the computer screen can be simultaneously displayed on the DisplayPort
device.
To connect a video or audio device to the DisplayPort:
1. Connect one end of the DisplayPort cable to the DisplayPort port on the computer.
