How do I enable 3 displays on my Dell laptop with docking station?

Hi there,

I have a Dell Precision M4400 noteboox with a NVIDIA Quadro FX770M card (with the lastest drivers) and a corresponding Dell docking station (with the model number PR02X) with 2xDVI and 1xVGA port at the back.

I would like to have 3 displays setup, 2x external LCD screens (can be connected via 2xDVI or 1xDVI and 1xVGA) and the laptop display. I have tried using the Windows control panel option with no success, and the NVIDIA Control Panel software which detects the third display but doesn't let me enable it.

Is there a way that I can have this setup with the current hardware I have? FYI, I am using Windows Vista Ultimate 32-bit.

    as far as i know u can only connect 2 screens at 1 videocard, in this case 2 X DVI or 1 X DVI and 1X VGA.

    if u want to connect 3 screens i can suggest u the Matrox Triplehead2go. this can do the job u want it to do.

    Matrox have a device called Dual head 2 go. IT is a great system and I have used it many times the output is verry crisp and clear and you dont have to mess around with multiple gfx cards trying to get them to work it apeares to your computer as a single monitor conected to your gfx card.
