My boss has a Dell desktop dual monitor 2007FP connected by VGA but both have DVI. He wants to get a third monitor placed on his treadmill to connect all three. I've spoken to Samsung and Dell and they've told me different things and I want to make sure I am getting the right things before I purchase anything.

One told me to purchase a graphics card with 3 DVI ports which I can't seem to purchase anywhere.

Another said a graphics card and a DVI adaptor are necessary.

Does anyone know the simplest way for me to connect these monitors?

I appreciate any help. Thanks!

Just get another, cheap, card - but first make sure that the motherboard can take a second card. Few standard/non-gaming cards support more than 2 monitors - unless you have something pretty dang new. – nerdwaller Jul 3 '13 at 20:57

It's not as simple as just purchasing a card with 3 outputs.

Check what expansion slots are free in the desktop. 2 of the following cards will do the job if you have enough space on the motherboard for both of them.
