Attaching an external monitor
Your computer can support a maximum video resolution of up to 2048x1536 (with an external monitor
attached to the VGA connector) or up to 2560x1600 (with an external monitor attached to the Mini
DisplayPort connector), provided that the external monitor also supports that resolution. For more details,
refer to the manuals provided with your monitor.
You can set any resolution for either the computer display or the external monitor. When you use both at the
same time, the resolution of both is the same. If you set a higher resolution for the computer display, you
can see only part of the screen at a time. You can see other parts by moving the image with the TrackPoint
pointing device or another pointing device.
You can move the display output to the computer display, the external monitor, or both in the Display
Settings window by pressing Fn+F7.

2. Connect the monitor to an electrical outlet.

output on the external monitor, the computer monitor, and both monitors.
Note: If your computer cannot detect the external monitor, right-click on the desktop, then select Screen
