I have two old VGA cards.

One of them is a MX440 NVidia card.

The other is a PCI Rage XL.

Is there a free tool that would allow me to mirror these cards?

I can't seem to find it anywhere on the web.

Just change the flag that says which is the primary desktop.

For your demo, make the second monitor primary instead of extended. Change it back when you're done.

Or maybe get a VGA splitter – you can then hook two monitors to same port.

I don't get it. 1. Which flag is that? 2. If I change this flag, wouldn't this just change the primary monitor? Or can I have two primary monitors? A splitter wouldn't help me much. Sometimes I'd like to use the monitors independently. Other times, I want them mirrored. A splitter would solve the mirroring problem. But it wouldn't allow me to change this programatically. –  Luiz Angelo Oct 25 '12 at 10:39
