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 F6. 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 F6. 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.
