I have finally set up my device. It connect well with my notebook and become an external monitor for my pc.
5 stars is given because I asked many questions about failing connection problem with my smartphone / my other concerns. The staff replied technically.
Suggestion ( but I don't know whether there is a market):
It is perfect if a HDMI to mini hdmi adaptor / cable can be ordered directly.
1 star deduction:
Reason : an occasional turning black for 1 sec for the monitor. I don't know what's up and haven't asked customer service yet. I will do it then. I hope the display card will not be affected.
