Using an External Monitor: Dell™ Inspiron™ 7500
Use the 15-pin video 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, desktop, or other level surface near the computer.
2. Connect the external monitor's video cable to the computer.
Plug the monitor cable connector into the matching video 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 video 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.
The video image can be displayed on an external monitor, on the computer's display, or on both simultaneously. To toggle between the three
display modes, press <Fn><F8>.
If the external monitor is turned off when you boot the computer, and if the Video Display Device category is set to CRT Mode in the Main menu
of the Setup program, the computer 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.
Whether you are using an appropriately equipped multifrequency monitor only or an external monitor and the built-in display simultaneously, you
can display up to 256 colors at a noninterlaced resolution of 1400 x 1050 pixels at a 32-bit color depth..
NOTICE: 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.
NOTE: When the external monitor and built-in display are used simultaneously, the refresh rate is always 60 Hz.
