I have 2 different docking stations with dual monitor outputs that ran great in 10.8 and now on 10.9 I am getting the "only 1 of the 2 monitors" comes up + the laptop display.
Using 2012 Macbook Pro with all Maverick updates, Lenovo's USB3 universal docking station with dual dvi and the Targus usb3 dvi/hdmi docking station. (both have the display link sticker on them)
I can plug in 1 monitor into either port and it comes up, then the 2nd one does not. SysPref > Displays shows there are 3 displays but only 2 are "on".
