I have a Latitude E6430 running Windows 7 connected to a Dell E-Port Plus Replicator PR02X. I have a ViewSonic VA2431wm 24" and a Acer V226HQL 22" display connected to the dock using the Dell DisplayPort / Display Port to DVI Video Adapter Cable Converter - 023NVR. The laptop doesn't have the NVIDA card installed only the Intel HD 4000 graphics card.
I have tried various configuration but I cannot get both monitor to stay active once the laptlop is open (and its monitor is active). After I closed the laptop then both monitors are active again. Based off of the information from Intel regarding the Intel HD 4000 graphics card, I should be able to run all 3 displays without error. I have updated my graphics card driver to veriosn 9.18.10.3165.
I have included my dxdiag and screenshot of my Intel HD Graphics Control Panel. Any assistance is greatly appreciated. The below post (same issue) has been very helpful yet the issue was still not resolved.
