CHAPTER 3: CONNECTING DEVICES
Connecting External Displays
If you want to enjoy your computing environment on a bigger scale visually, or
extend your desktop area, you can connect an external display such as a standalone
monitor, an LCD TV, or a projector.
NOTE: The external display connections in your Alienware notebook are
connected to your discrete graphics card(s). When you want to use an
external display device, turn off the integrated graphics (). This
will active the discrete graphics in your computer, and enable the external
display interfaces.

display. If your display does not have a DisplayPort or HDMI connector, you can
connect to the display using either a VGA cable from the notebook’s 15-pin VGA
connector or a DVI cable via a DisplayPort-to-DVI adapter. This adapter can be
purchased through Alienware, Dell, or other electronics retailers.
