I have a Gateway mx3422 notebook. I cannot get the display to clone when I hook it up to a projector. The notebook screen goes black and the display shows on the projection screen.

    Thanks for responding. When I hook up the cable for the projector and
    boot the computer, the opening screens show on both displays. However,
    at some point in the booting, the notebook display goes dark and all I
    see is the display on the projection screen. Working on that screen, I
    open the Nvidia control panel and have three options showing for the
    display; single display, clone, and dual view. I select clone, Apply,
    and Yes to keep the configuration. It shows the two displays, and lists
    the notebook as the primary display for Windows, but nothing shows up
    on my notebook screen. When I use the Fn key with F4, it simply reverts
    the setting to the single display option.

So, as soon as you hook up the projector, the LCD goes blank? 2 things control the output, the function key to enable the external video and the display settings in Windows. If Windows shows 2 displays (Control Panel, Display, Settings), then change the setting there to enable cloning. If it only shows one display, try the function key for the external video--something like function key F10 or thereabouts. (Well there could be 3 things, the other would be the display driver.)

Bummer, typed that, then found:

Q: How do I view the notebook display on an external monitor or projector in Windows XP?A: You can use your notebook for giving presentations by connecting an external monitor or projector to your monitor (VGA) port. Your notebook supports simultaneous LCD and CRT display. Simultaneous display lets you control the presentation from your notebook and at the same time face your audience. Note: If an external monitor or projector is connected and you close the LCD panel, your notebook turns off the LCD panel, but does not enter Standby mode.
Follow these steps to use a projector or external monitor.

  1. Turn off your notebook.
  2. Plug the projector or monitor cable into the VGA port on your notebook or the optional port replicator.
  3. Turn on your notebook.
  4. Plug the projector's or monitor's power cord into an AC power source and turn it on. Windows® recognizes the new hardware and searches for its driver. You may need to install the driver from the disc supplied by the manufacturer or download the driver from the manufacturer's Web site.
  5. After the driver is installed, right-click any empty space on the desktop, and then click Properties.
  6. In the Display Properties dialog box, click the Settings tab.
  7. On the Settings tab, right-click the second monitor icon (labeled 2), and then click Attached.
  8. Click Apply.
  9. Adjust properties such as Screen Resolution or Color Quality if necessary.
  10. Click OK.
Note: Press FN+F4 to switch between viewing the display on the LCD panel and viewing the display on the projector or monitor.

The laptop screen is black when the computer is conencted to a data projector. No function keys solve the problem. What to do?

This is more than likely a function of Windows and not the laptop. Go into the control panel and then into Display. In Display click on settings and see if you have more than one display listed, you should have the laptop display and the projectors also listed. Set the projector display to clone the laptop display and make sure the laptop display is the primary display. Click on identify and this will show you a 1 and 2 for the appropriate display. Set the accordingly and you should be in business.

You might have not enabled your computers second display.

This is actually a very nice feature, because you could run your powerpoint slide on the monitor while still running your normal applications on the laptop screen.

Go into control panel, display properties and then click on the "second" monitor (you could click on "Identify" to see which is which) and then select the "expand my desktop onto this screen.

The LCD display will be just a normal background, but you can drag windows from your laptop screen onto the LCD and back.

Hope this helps

No display on expantion vga port for projector

The problem might be related to your native screen resolution. The C702TU laptop has a resolution of 1280 x 800. Most projectors do not support this resolution and if you cloned the main display, your projector cannot sync at this resolution. Look for an option to output a second display )instead of cloning) within your display settings. If your projector is plugged into your VGA port and turned on, Windows usually detects the second display automatically. Change the resolution on the second screen to something like 1024x768 or 800x600. These resolutions are supported almost universally across projectors.
