I have read many post on this subject from many owners.
My panel is running 1013 which is the latest listed here :-
the unit is unable to be brought from deep standby (ie blue light steady)
if the blue light is flashing the unit powers on every time.
I have tried every solution from ever post and arrived with the following conclusion
the monitor has a firmware bug in deep standby that prohibits the monitor from exiting standby when connected by Displayport
can anyone help or suggest how this issue to raised in Samsung? surely its not a return.....
