Using an External Monitor: Latitude LM

Use the 15-pin monitor connector to attach an external monitor to the computer. If you reconfigure your hardware, you may need pin number and signal information for the monitor connector. Use the following procedure to connect an external monitor:

1. Turn off the external monitor.
   Set the monitor on a monitor stand, desk top, or other level surface near the computer.

CAUTION: Do not place the external monitor directly on top of your portable computer, even if it is closed. Doing so can crack the computer case, the display, or both.

2. Connect the external monitor's video cable to the computer.
   Plug the monitor cable connector into the matching monitor connector at the back of the computer.
   If the cable is not permanently attached to the monitor, connect it to the monitor also.
   Tighten all the screws on the monitor cable connector(s) to eliminate RFI.
3. Connect your external monitor to a grounded AC power source.
   Plug the 3-prong connector on one end of the monitor's power cable into a grounded power strip or some other grounded power source.
   If the cable is not permanently attached to the monitor, connect it to the monitor also.

Press <Fn><F8> to display the video image on an external monitor, on the computer's display, or on both simultaneously.

If the external monitor is turned off when you boot the computer, the computer still sends the video image to the external monitor. In this case, you do not see an image on either the computer's display or on the external monitor. To resolve this situation, turn on the external monitor or press <Fn><F8> to switch the video image to the computer's display.

If you are using an appropriately equipped multifrequency monitor only, you can display up to 256 colors at a noninterlaced resolution of 1024 x 768 pixels. When you use an external monitor and the built-in display simultaneously, the highest resolution supported is 800 x 600 pixels and 256 colors.

NOTE: If you are using your external monitor at a resolution greater than the display's resolution (for example, 1024 x 768), the simultaneous display feature is disabled. You cannot switch to the built-in display (pressing <Fn><F8> will have no effect). To use the external monitor, switch to a resolution that your display supports, or disconnect the external monitor and restart the computer. To use the built-in display, switch resolutions to 800 x 600 pixels (<Fn><F8> will now work).

If you are using a resolution of 1024 x 768 on the built-in display, or if the Video Mode option in the Setup program is set to Simul, the panning drivers allow you to view the image in sections on the display.
