Hi there,<br />
<br />
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.<br />
<br />
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.<br />
<br />
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.<br />
<br />
Thanks.<br />
Chris.

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

A monitor or a display is an electronic visual display for computers, usually comprised of the display device, circuitry, casing, and power supply. The display device in modern monitors is typically a thin film transistor liquid crystal display (TFT-LCD) thin panel, while older monitors used a cathode ray tube (CRT) about as deep as the screen size. They are connected to the computer via VGA, DVI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors and signals.
