My notebook is an Asus S46CB. It come with a GForce 740M and an Intel Graphics HD 4000. When I use two monitors (notebook + extra monitor), it shows screen interference in the notebook screen. If I force the use of the Gforce it doesn´t happen. I have already changed the cables and have updated to the last version of the drivers. The Intel Graphics driver is 10.18.10.4252.
What could I possibly do? I´m thinking of rolling back to Windows 8.1.
