I have a 2 month old E6530 laptop that sits on a docking station while at work.  The docking station has two monitors connected via Display Ports and I have always been able to use these two displays and the built in display at the same time.  Today when I cam into work, I noticed that the two monitors connected through the docking station were not working, so I went into the screen rez menu and tried to turn them back on as I sometimes have to.  Only when I would have monitor 1 (built in) and monitor 2 (DP1) turned on, if I told monitor 3 (DP2) to turn on it would shut off monitor 2.  Then monitor 2 would turn off monitor 3.  I then went into the Nvidia display settings and tried to do the same thing, and when I check to turn on the third monitor I get a message saying " this GPU supports up to 2 displays"

I have upgraded the nvidia driver to the latest version 320.00 and my BIOS to A11.  Still the same issue, any ideas?
