Hi, I have a Lenovo W540 laptop that suppost DP1.2 and a U2415h monitor connected with the supplied mini dp to dp cable.  I am trying to also connect to a Sony television.  I have a DP to HDMI adapter that is dp1.2 compliant and I have turned on the 1.2 mode on the monitor.  I have also updated the monitor drivers from dell.  No matter what I do, I can't get the computer to recognize the TV or get anything to display on it when it is daisy chained.  Am I doing something wrong or for some reason can you not daisy chain through HDMI with an adapter?
