I am trying to figure out if I can use a 3 monitor setup with my T580 laptop. I have the laptop docked on the 'ThinkPad Pro Docking Station'. I am using the two DisplayPorts from that to go to two HP EliteDisplay E243i monitors. I have a third monitor, a HP Compaq LA2206x that I connected to the HDMI port on the laptop but when running any of the monitors from the dock, the HP Compaq will not be detected. The integrated graphics card says it can drive 3 monitors so I'm not sure why this won't work? Does the HDMI port go to sleep/shut off when monitors are being used through the dock?
