Considerations for connecting an external monitor
• When installing an operating system, you must install the display driver for your monitor that is provided
with the computer, and the monitor INF file that is provided with the external monitor.
• If you set a resolution higher than the resolution you are using on the computer monitor, and use an
external monitor that does not support that resolution, take advantage of the virtual screen function,
which enables you to display only a part of the high-resolution screen image your computer produces.
You can see other parts of the image by moving the screen with the TrackPoint pointing device or another
pointing device.
• If the external monitor you are using is outdated, the resolution and the refresh rate might be limited.
Using the mini DisplayPort connector
Your computer has a mini DisplayPort connector, which is a digital display interface for connection to
various external devices, such as Cathode Ray Tube (CRT) monitors, LCD monitors, projectors, or even
high-definition televisions. This compact connector enables a plug-and-play setup and supports adapters
that can plug into DVI, VGA, or High-Definition Multimedia Interface (HDMI) connectors.
The mini DisplayPort connector of your computer supports audio as well as video streaming.
