IMPORTANT: Be sure that the external device is connected to the correct port on the computer, using the
correct cable. Check the device manufacturer's instructions if you have questions.
NOTE: Refer to the Getting to know your computer on page 3 section for information about your computer's
video ports.
VGA (via optional docking device or expansion port device)
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 on the optional
docking device or expansion port device connected to the computer.
2. Press fn+f4 to alternate the computer 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 (via optional docking device)
The DisplayPort connects the computer to an optional video or audio device, such as a high-denition
television, or to any compatible digital or audio component. The DisplayPort delivers higher performance
than the VGA external monitor port and improves digital connectivity.
