Hi,

To connect your laptop to a video projector, just follow these steps:
1. Connect your laptop's external video connector to the video projector.
You can use either the S-Video or external monitor port. You can do this with the laptop on or off, though eventually you do need to turn it on. Oh, what the heck: Turn on the laptop now!
2. Connect the laptop's audio-out port to the projector or to the location's sound system.
3. As long as you're connecting things, see whether you can plug the laptop into an AC socket.
No sense in wasting battery power for a presentation - or running out of battery juice in the middle of that presentation!
If your laptop has Windows Vista, go on to Step 4a. If you have Windows XP, skip to Step 4b.
4. a. In Windows Vista, open the Personalization icon in the Control Panel and then click Display Settings.
4. b. In Windows XP, open the Display icon in the Control Panel and then click the Settings tab.
The job of the Settings tab, shown in Figure 1, is to confirm that your laptop's hardware is working and that it recognizes the video projector as the external monitor. For most modern laptops, this happens automatically; the only time you really need to use the Settings dialog box is when things are hinkey.
5. Check the image; preview the slide show.
At first, the projector may just show your laptop's Windows desktop. That's not why people are coming to the meeting, though. Take your presentation for a "pre-run." Load that main slide and ensure that it shows up on the screen. If so, you're ready to go.
If the slide show has sound effects, preview them, as well, to ensure that the sound system is working.
6. Close the laptop's lid and wait to be introduced.
You can just leave your laptop at the podium, lid closed, ready to go. When you open the lid, the presentation is ready to run. If there are too many people around and security is a concern, you may want to take the laptop with you.
At other times, the video projector acts as the laptop's second monitor. The laptop shows the regular laptop screen, but the presentation appears on the video projector. (That's just PowerPoint being smart.)
Here are a few tips about making your laptop/projector connection a smooth one:

  • Be sure to pack an extra bulb when you're using your own video projector. You want to be able to replace a burned-out bulb quickly, and they usually don't sell those bulbs in the hotel's sundry store.
  • Some laptops sport a special function (Fn) key on the keyboard that you can use to activate the external video port. You may need to press this key to switch the display over to the video projector.
  • Some laptops may have dual video built in, allowing you to use the video projector as a second monitor. To confirm this, open the Display Properties dialog box and click the Settings tab. A second monitor should already be configured. If so, you're set and ready to go!

Goodluck..

    Make sure you press the Fn +F8 to get the display..



    Try this method. Firstly, make sure that both your laptop and projector are off. Connect your laptop to the projector. Switch on the projector. Next, switch on your laptop. The image on your screen should be replicated through the projector. Note that because the maximum resolution of your projector is 800 x 600 you will need to set your laptop to the same resolution. This is
    because a projected image is the same image as displayed on the laptop screen and there is nothing you can do about this - if you want a higher resolution you will need a projector with a higher resolution.

Hi,

Try lowering your laptop's screen resolution and refresh rates to the lowest possible.

Additionally, you need to press Fn + F? keys on the laptop to cycle on laptop display, laptop display + external; display, external display.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

    Hi again,

    In some instances, it may be necessary to power on the projector first before booting the laptop. The reason behind is that the external video of the laptop will be activated (on boot) when it senses that their is a consumer at the other end (the projector).
