I have a Sharpvision XVS96U LCD Projector, that was working just fine with an older computer. I decvided to upgrade to a newer, faster computer with more memory, and had a Dual VGA video card installed so I could display the image on a screen for the public through the projector, and at the same time manage the images on the primary monitor. Problem is, I am getting nothing through the projector, I have run the Dual mode video wizard many times, and yet the problem persists. I have set up my primary and secondary monitors, and nothing seems to work.Do you have any ideas how to get the iomage to display through the projector?

If your projector displays no image, this could be a variety of problems. First, check that the projector has power. On the top of the LCD or DLP projector should be some lights. With power, those lights will be on. If it has power, check to make sure that the projector lamp is firing. If so, go to the source. Make sure that it is connected with a VGA cable or USB cable to your computer, or with an RGB cable, S-Video cable or DVI connection to your VCR/DVD Player. From a laptop computer, the VGA cable should be connected to the VGA out connection, and into the VGA in connection on the projector. Are both ends tight?
If everything has checked out so far, the solution probably lies with the external monitor port. Check this by holding the Fn key on the keyboard, then press the F7 key. (On some computers, the key might be F5 or F3. Try these if F7 doesn't work) Each time you press the Fn / F7 combination, you will cycle your display through the following settings:
* Press Fn / F2 or F2 once: The laptop screen only * Press Fn / F2 or F2 twice: The projector port only * Press Fn / F7 or F2 three times: Both the laptop and projector port * Wait a few seconds after each time you press the key combination to let the LCD or DLP projector refresh. Nine times out of ten this will result in seeing your projected image.
this should help you :)
Hi LCD projectors have revolutionized the audiovisual industry. With a few clicks of the mouse and strokes of the keyboard, whatever you type on your computer appears instantly on a projection screen in real time. If you have never experimented with an LCD projector, however, do not worry. You can learn how to use an LCD projector.
Plug the LCD projector in to a power outlet. Completely plug the power cord in to the back of the LCD projector.
Step 2Use a VGA cable (usually a 15-pin male to male) to connect your computer to the LCD projector. Insert one end of the cable into the VGA connector (sometimes this connector is blue) in the back of your computer and do the same in the back of your LCD projector. If the LCD projector has more than one VGA connector, choose the one that says something like "line in" or "in from computer."
Step 3Power on your laptop. Turn on the LCD projector. It may take a couple of minutes to warm up. Open the computer file or document you wish to display. When you are ready to project your image, press "Function" (Fn) plus "F8." This combination of keys sends your computer's display to the LCD projector.
On that Dell, you have to tell the laptop to display the image on an external unit--look on either F4 or F8--you will find a small TV screen symbol. You have to press and hold "alt" and press the key. The options are, 1-show image on just the laptop, 2-show the image on the laptop *and* something else, (like a projector), or 3-show an image on JUST an external display. NOTE: Sometimes, you have to turn on the projector FIRST, then immediately turn on the laptop so they boot together--just one of those strange things...(remember, **for example** first press of "alt" F4 will get you laptop and projector, second press of "alt F4 will get you JUST the projector, third press of the keys will bring you back to just the laptop)---Rick
resolution issue. reset the settings to factory default. if that doesn't solve it, make sure the resolution on the projector matches what is on the computer. and it should take mac ok. also check the cable.
