Adding two screens to an VGA spliter will only duplicate the image on both monitors.

Most versions of Windows 7 can, the question is can your hardware? To run dual or even triple screens you need a video card(s) that supports it and has the necessary connections. As mentioned, a video splitter just feeds identical signals to multiple monitors. All the monitors would display the exact same image. Your PC would only see the one connection. Looking at your system specs in your profile, you could probably run two monitors and extend your display across the two. You would have to check your manual to be sure. If you are running Windows 7 Starter I don't believe that supports extending your desktop so you may want to check that first.

You still need a graphics card with multiple outlets to run multiple screens.

According to your specifications you have Intel GMA3150 graphics in a netbook.

So you probably have a VGA port for an external monitor.

When you plug in an external monitor you will have a designated hot key to swap to it.

There is no way you can plug in two monitors running on two video channels on that hardware.

I think you're confused a little.

The equipment in the link has the Nvidia ION MCP7A-ION Chipset, your spec's as completed on the forum say otherwise...

Yes, I know, I'm running dual monitors in extend mode. If you hold down the Windows key and then press the P key you will get the selection screen. Your hardware still has to support running three monitors though to use three monitors. My GT220 only supports two monitors max. I could connect another one but my display will only even extend across two displays. The third monitor, if it displays anything at all, will just mirror one of the other two monitors. To run three monitors i would have to add a second video card or upgrade to one with triple monitor support.
