my dell laptop is no longer outputting video through the dock after some driver updates. I tried to revert the driver (synaptics) but now it says it "cannot find synaptics MST DP hub IC" so it won't install. If I connect the monitor directly to the laptop, it is ok, just not through the dock. Sound and USB work fine on the dock. Any help would be appreciated.
