I am trying to run a 3rd monitor display any way possible, whether an external monitor or the laptop monitor, makes no different. Problem is, no matter which setup I use, cannot get but two monitor to display. I need to know how to verify if my Graphics Card and/or Processor board support > 2 displays. I have read multi forums & tried various docking station, (Dell Docking Station USB 2.0 PR02X E-Port Plus Replicator + PA-4E AC Adapter), outputs, e.g., Display Ports & VGA. I am using the DVI-to-Display Port for two monitors, VGA-to-VGA for another. I have also tried the HDMI-to-Display Port for one of the monitors. Nothing works. I have attached the screen-shots from the Intel Control Panel, along with the DxDiag Output.

Thank you for contacting Intel Communities.
I found the following article from the system manufacturer (Dell) that you may find useful for the issue you are having:
How to configure three (3) displays on a Dell Latitude Notebook with Intel HD 4x00 Graphics
NOTE: This link is being offered for your convenience and should not be viewed as an endorsement by Intel of the content, products, or services offered there.
From the link above, you can find the following:
"WHAT DOES NOT WORK (HD 4000/HD 4400 ONLY)
- If you use ANY ONE of the following items, you WILL NOT be able to configure 3 displays.
- Any DisplayPort cable adapter. (This was verified in the testing lab, regardless of active or passive, VGA, HDMI or DVI using a DisplayPort cable adapter prevented 3 displays from working.
- Any display that does not natively support video input from DisplayPort. (Again, no cable adapters, at all).
- i3 Processor. (i3 processors are not Intel 4x00 graphics, they are Intel 2500).
- Any dock other than the Dell E-Port Plus.
- Any HDMI connected display."
Hope this information helps.
