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.

Connecting an external monitor

To attach an external monitor, do the following:

1.Connect the external monitor to the mini DispalyPort 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 enables you to switch between viewing 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 resolution. Click the Detect button.

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 might appear on some displays, such as the shutdown screen of the Windows operating system. 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 external monitor type

To set your external monitor type, do the following:

1.Connect the external monitor to the Mini DisplayPort connector, and then connect the monitor to an electrical outlet.

2.Turn on the external monitor.

3.Right-click on the desktop, and click Screen resolution.

Note: If your computer cannot detect the external monitor, click the Detect button.

4.Set Resolution.

5.Click Advanced Settings.

6.Click the Monitor tab. Check the monitor information window to ensure that the monitor type is correct. If it is, click OK to close the window; otherwise proceed with the following steps.

7.If more than two monitor types are displayed, select Generic PnP Monitor or Generic Non-PnP Monitor.

8.Click Properties. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

9.Click the Driver tab.

10.Click Update Driver.
