Can this laptop run 2 external displays plus its own?
At work, I have an HP 8470p laptop. Running Windows 7 Enterprise 64 bit. It has video out connectors in VGA and DisplayPort. I can run the laptops' built in display plus an external monitor with no problem, but I want to add an extra external monitor, for a total of 3 displays up and running their own independent screens at any time (extended displays).
If I run video out of the DP and VGA, one monitor or the other will work, but not both. Either one hooked up alone runs fine.
I tried using a docking station to run VGA and DVI out to the monitors, but the same problem. One monitor or the other will work, but not both. Using DP on the docking station instead of DVI didn't help either. I ran the docking station off a 150 watt power supply, so power should not be the issue.
Is the laptop incapable of running 3 displays, or does something have to be done in a certain way?
In display properties, when running the DP for the 3rd monitor, it will show 3 monitors with displays extended to both, but the monitor itself gets no video signal.

I'll have to see if we have any VGA splitters or USB to video adapters around here, I don't know if that'll help or not.
