Dual-Mode DisplayPort
The Dual-Mode 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 Dual-Mode DisplayPort delivers
higher performance than the VGA external monitor port and improves digital connectivity.
NOTE: To transmit video and/or audio signals through the Dual-Mode DisplayPort, you need a Dual-Mode
DisplayPort cable (purchased separately).
NOTE: One Dual-Mode DisplayPort device can be connected to the Dual-Mode DisplayPort port on the
computer. The information displayed on the computer screen can be simultaneously displayed on the Dual-
Mode DisplayPort device.
To connect a video or audio device to the Dual-Mode DisplayPort:
1. Connect one end of the Dual-Mode DisplayPort cable to the Dual-Mode DisplayPort port on the
computer.
