3 Screens on iMac?

[NicksiMac]

So I was wondering, I saw a VGA cable that split into two would I be able to run 2 screens on my iMac? I have a early 2010 21.5" iMac? It will connect through mini display port and then branch to two screens to have 3 in total, iMac and 2 screens?

You could, but the other screens would be showing the same thing, so it wouldn't be very useful.

That's just a plain signal splitter. The two monitors connected to it will display the same thing.

If you want 3 monitors (or more) on your iMac, you're going to need a DisplayLink device to do it.

Have you looked at the Matrox DualHead2Go?
