Display Drivers for intel HD 4600

I have a Dell Latitude E6540 attached to a E-Port Plus docking station.  Before the latest update of the video driver I was able to use all three ports of the e-Port (1-VGA and 2-DVI) to run 3 external monitors.  Since the update last week, I lost the ability to connect to the 2nd DVI port.  This puts me in a bad place since my work requires three full size monitors.  Sure, I can get a third monitor by opening the cover on the laptop, but that screen is too much strain on my eyes for what I am doing.  Is there a way to either return to the April 2014 version of the video driver or are there some settings I am missing in the Driver setup?
