Hi,

I'm using a Samsung Ativ tablet PC connected to a monitor via micro-hdmi to vga convertor.
usually everything working ok until recently the screen started flickering all of a sudden.
Im not really sure how to attack this kind of problem.

the PC is on duplicated display mode and it flickers randomly , i can work 15 min and afterwards it will start , and it can flicker from the beginning.
the Pc is connected to its power supply all the time , im thinking to examine the issue with another screen and see if it still happening . I even tried to lower the resolution but it didnt make any improvment .

the Graphic card is intel HD graphics 4000 , Resoution : 1920X1080 - usually working on word and outlook sometimes website but nothing more than that.

any Ideas where to look or what to do ?

thanks,
Noam
