Hi again.
Just to make an update on my experience :
I updated the intel 3165 drivers and now the wifi conection is much more stable, even with the bluetooth mouse conected.
My unit hinge is very good. No problems with that.
I also disabled Cortana for a boost in performance.
I made all updates to windows 10, even the creators update and it resolved the problem with high resolution screen and some blurred letters.
For now is working good.
Thank you all for your help.
