3 monitors on an Optiplex 330?

Hi all,

First, let me qualify this by saying I'm currently running two monitors (I forget the video card - it's at home) but have most everything turned WAY down/off since I'm only using this system for IFR practice.

That said, I'd like to add a third monitor dedicated ONLY to the out-the-window view.

Current setup is all instruments on main screen with a little out-the-window view, 2nd monitor contains radio stack and GPS.

The computer, and Optiplex 330, runs it just fine, but I'd like to free up real estate on my main monitor to add some stuff.

I've looked around but am not familiar with doing this other than having seen the Matrox TripleHead, but I'm not sure if my system could support that.

Any help appreciated-

thanks,

Andrew
