If I use that, will the image be displayed on both screens like its one big screen? Will I be able to drag a window back and forth between both screens? My notebook doesn't support two monitors with its internal video card I am worried that the USB adapter will only display the same image on both screens
I don't think you need to worry about that. These USB-VGA/DVI devices have drivers that would work. Windows (XP, Vista, etc.) supports multiple monitors and you can opt to have the added monitor displaying the same image or a different part of your desktop.
I thought you were kidding. years ago I bought a hp pavillion zt3000 for $1600 which allowed you to have a dual monitor. today a more power computer goes for less than $400 without the dual monitor feature. I wonder what else it has that u cannot get now. it was also built like a tank.
I agree that $1800 is way too steep for having a gadget for the purpose of projecting your images to a few external monitors from your laptop. You can buy a desktop computer for way less than that. e.g. $500. There is some software that allows you to share image displays on a second computer over the network connection. I did a trial before and it worked okay.
If you travel a lot, some of us do, a laptops with 2 or 3 extra monitors is handy but I agree $1800 is out of hand. I travel with a laptop, two travel monitors, a portable printer and micro projector. It all fits in a carry on bag.

I have the same problem I am attempting to connect two external monitors to my laptop. What I have done is obtained a VGA splitter that allows me to connect two external VGA devices to a single VGA port on my laptop. What has happened is exactly what I thought would happen (but hoped it would not), both external monitors are showing the same picture. My laptop screen is screen 1 and my first and second external monitors are screen 2 . The external monitors show the same picture and for me that defeats the purpose of having two of them. I was wondering if anyone has any suggestion on how make the second external monitor screen 3, so I have 3 separate images on each screen. I have tried display options but my Vista laptop seems to think that I have only one external monitor and there is no mention of the second one. I am attaching a screenshot of the splitter so you can visualize what I am attempting to do.
