I have my laptop in a docking station that has 2 DVI-D Male/Male connections. I have a DVI-D cable running from each to an LG monitor.

When I go to the display settings, I can get one of the monitors to extend out from my laptop, but I cant get it to go to the third one.

Can anyone help me out with this?

There is a third monitor listed on the screen with "3" right in the box, but the box is grey.

It also says "W2361" in the display drop down menu.

Just noticed that it is the name of the screen.

I have figured out how to extend the display from the desktop to one monitor, then change it to the other monitor, but I can't get it to extend out to all three.

I looked at the specs and it says that it supports multiple monitors Tech Specs

Are you trying to set that up in the windows control panel or the Nvidia control panel? you might have better luck in the "NVIDIA Control Panel" I see NView mentioned on that spec page you linked to, is that special software? Maybe you need to run that to get three displays setup? Multi monitor support just means more than one, it doesn't necessarily mean three or more. If you are limited to two displays you could try disabling the built in screen, to see if it will at least let you use the two external ones.
