Hi shailendra,
Absolutely. You can install more PCI video cards and add more monitors. The better cards are available from ATI. Their 9200 series should work for you. You can also check Nvidia, but they get a little pricy, and don't have as many options as ATI does.
Let me know if you need any more help.

Thankyou Vishad,
I have one more little complex question. is it possible to make these monitors act as one ( one image out and it gerts distributed into multiple screens) I'm sure this is not that easy but i was wondering if there are any products like that available in the market that will help me do that. Thank you.

Sure. Here are the steps:
A. Install your video cards (remember to download and install the latest drivers from the manufacturer's website BEFORE installing the card itself).
B. After you reboot your system you should be sent either to the login blue screen or the desktop (depending on your security options). Only one monitor will act as the starting desktop. Usually it's the monitor plugged in the left-most DVI connection in the #1 PCI slot (the PCI slots are numbered for this purpose). The other monitors will be the "expansion"--they'll have a background and you can fly through them by moving your mouse through one screen to the next.
C. You'll need to go to System Preferences-->Displays-->click on the Arrangements tab. There will be a screen layout, where you can click and drag your screens to whatever output position you want. Default is best. At the bottom of the Arrangements tab is a box labled "Mirror displays." Click the box and wait for your computer to set the output for your monitors.
D. After that all your screens should mimic your one main desktop screen. Whatever action you perform on that screen will appear on all the others. You won't be able to "fly" through the other screens now; they will simply mirror what you're doing.
If you have any further questions, feel free to ask.

Hi VishadThank you once again.
What i am trying to do is not mirror the desktop on other screens but make four monitors act as one. Let's say if i am looking at a movie i want to use four monitors to look at that one movie. I hope i explained that well. I am trying to send one image into four projectors but have them act as one single projectors so that i can move individual projectors in different directions splitting the image.
Thank you for your help.

Well, the default setting for multiple monitors is for the extra monitors to act as the expansion of the main desktop. Unfortunately, if you want to drag the DVD Player so that its picture spans over four monitors, it won't work. You can either expand it to fill one screen, or grab the whole window and move it partially into the monitor field. That's it. You can't "split" the image over four monitors. At best, you can cut it in half over two monitors.
That's why mirroring works best in this case.
I don't know if Windows Media Player would support this type of window stretching. One player that WILL do it to a degree is VLC Player. I tested your question with my dual monitor system, and the image stretched over quite well. Unfortunately, once the image covered both monitors VLC had a difficult time organizing the scale correctly and gave me a blank white screen.
The only way to do what you want would be to get multiple computers with dual monitors. That way you could control the windows as you wished. Unfortunately, that would require multiple copies of your movie.
You can try VLC Player to see if it will work for you. It's a freeware application and is available at
www.videolan.org/vlc/.
Let me know if you need any more help.
