dual displays

I have a Dell Precision 390 Windows XP Pro system here with an NVIDIA Quatro FX3450 graphics card. I have been given the task of cloning the desktop on 2 different displays at 2 different resolutions.

I have been able to clone the desktop to the 2 different displays, but it seems that what ever the resolution on the main display is, that is what the resolution will be on the second display.

Is what I have been tasked to do possible with this card or any other card?
