Hi all
I also have the similar issue of U3014 after power off , it goes into power saving mode and next power up ... it still remains in power saving mode.
On the same PC , I have DVI-D , HDMI and Displayport .
I tested that on the same monitor , Only Displayport will wake up .
For those having this problem and no going to ask for refund .... connect using Displayport.
For Dell --- Please look into why the DVI/HDMI doesn't wake up ....
