Thank you for your question. I have tried everything with no luck. I tried using a Ivanky dock and 2 Samsung 24in Curve monitors but only getting one display to work. I connected one of the monitors (the one that is working) with a HDMI cable from the dock to the monitor. The other monitor (not displaying) I had to use a Mini DisplayPort to HDMI. Not sure what the issue is. I have tried turning off the dock and computer, Nothing. Is there a way go back to the previous OS? Lets hope there is a fix to the OS.
