Attaching an external monitor Your computer can support a maximum video resolution of up to 2048x1536 (with an external monitor attached to the CRT connector) or up to 2560x1600 (with an external monitor attached to the HDMI port 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 or another pointing device. You can move the display output to the computer display, the external monitor, or both in the Display Settings window (in Windows XP Display Properties window). Connecting an external monitor To attach an external monitor, do as follows: For Windows 7: 1. Connect the external monitor to the monitor connector; then connect the monitor to an electrical outlet 2. Turn on the external monitor. 3. Change the display output location by pressing Fn+F7. This allows you to switch between viewing output on the external display, the computer display, and both displays. Note: If your computer cannot detect the external monitor, right-click on the desktop, then select Screen resolution. Click the Detect button. For Windows XP: 1. Turn off the computer. 2. Connect the external monitor to the monitor connector; then connect the monitor to an electrical outlet. 3. Turn on the external monitor and the computer. 4. Change the display output location by pressing Fn+F7. This allows you to switch between viewing output on the external display, the computer display, and both displays. Notes: • Do not change the display output location while a moving picture is being drawn-for example, while playing a movie or a game, or viewing a business presentation. Close the application before changing the display output location, or change the display mode before you open an MPEG file to play. • If you are attaching an external monitor that supports only VGA mode (640x480 resolution), do not view output on both the computer display and the external monitor. Doing so would cause the external monitor screen to be scrambled and the output not to be displayed; in addition, it could cause damage to the screen. Use the external monitor only. • If the external TFT monitor you connect has an analog interface, flickers or ripples may appear on some displays, such as the shutdown screen of Windows. This is caused by the external TFT monitor, and cannot be fixed by adjusting the external TFT monitor or the computer side settings. Setting the monitor types To set your monitor type, do as follows: For Windows 7: 1. Connect the external monitor to the monitor connector, and then connect the monitor to an electrical outlet.

Attaching an external monitor
Your computer can support a maximum video resolution of up to 2048x1536 (with an external monitor
attached to the CRT connector) or up to 2560x1600 (with an external monitor attached to the HDMI port
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 or another pointing device.
You can move the display output to the computer display, the external monitor, or both in the Display
Settings window (in Windows XP Display Properties window).
Connecting an external monitor
To attach an external monitor, do as follows:
For Windows 7:
1. Connect the external monitor to the monitor connector; then connect the monitor to an electrical outlet
2. Turn on the external monitor.
3. Change the display output location by pressing Fn+F7. This allows you to switch between viewing
output on the external display, the computer display, and both displays.
Note:
If your computer cannot detect the external monitor, right-click on the desktop, then select

. Click the

button.
For Windows XP:
1. Turn off the computer.
2. Connect the external monitor to the monitor connector; then connect the monitor to an electrical outlet.
3. Turn on the external monitor and the computer.
4. Change the display output location by pressing Fn+F7. This allows you to switch between viewing
output on the external display, the computer display, and both displays.
Notes:
•
Do not change the display output location while a moving picture is being drawn—for example, while
playing a movie or a game, or viewing a business presentation. Close the application before changing the
display output location, or change the display mode before you open an MPEG file to play.
•
If you are attaching an external monitor that supports only VGA mode (640x480 resolution), do not view
output on both the computer display and the external monitor. Doing so would cause the external monitor
screen to be scrambled and the output not to be displayed; in addition, it could cause damage to the
screen. Use the external monitor only.
•
If the external TFT monitor you connect has an analog interface, flickers or ripples may appear on some
displays, such as the shutdown screen of Windows. This is caused by the external TFT monitor, and
cannot be fixed by adjusting the external TFT monitor or the computer side settings.
Setting the monitor types
To set your monitor type, do as follows:
For Windows 7:
