Need "Video Card" for Notebook

[TechieSooner]

I've got a notebook I use in a docking station.
The problem is the docking station only has two graphics ports (one DVI and one VGA)... And no 3 or more port docking station is available for it.

So I need something, maybe that connects through USB, like this:

However all most all of these adapters say to "adding a second monitor", not a third. Would this work, connecting this to the VGA of the docking station?

Anyone at all?

I've used products similar to this. They acutally work pretty good. You can use it for a third screen.

I have a usb Video Card at work from this company and it works rather well.

Which would you suggest?
