VGA
The external monitor port, or VGA port, is an analog display interface that connects an external VGA display
device such as an external VGA monitor or a VGA projector to the computer.
1. To connect a VGA display device, connect the device cable to the external monitor port.
2. Press fn + f4 to alternate the screen image between 4 display states:
● PC Screen only: View the screen image on the computer only.
● Duplicate: View the screen image simultaneously on both the computer and the external device.
● Extend: View the screen image extended across both the computer and the external device.
● Second screen only: View the screen image on the external device only.
Each time you press fn + f4 , the display state changes.
NOTE: For best results, especially if you choose the "Extend" option, adjust the screen resolution of
the external device, as follows. Select Start > Control Panel > Appearance and Personalization. Under
Display, select Adjust screen resolution.
DisplayPort
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.
