Hi My name is John. I work for Volvo Cars USA. I currently have a client with an E7250 laptop. The client is not able to use a monitor in a Pro3x (E-portII) dock. Most of these docks use a DVI or an dock port connection. I have gone onto the drivers and software site and downloaded the Synaptics VMM3320 MST HUB Firmware Update. I installed the update successfully. After a reboot I still was not able to use those types of monitors. They kept flickering. Is there anything else I could try?
