I have a very annoying problem with my Asus laptop. I have a Nvidia GeForce GTX 950M graphics card with an HDMI port and I want to connect a second monitor to it. If I use the Intel graphics card, everything works perfectly fine. Instead, if I use the performance mode, the second monitor is completely unusable: it shows artifacts and remains frozen. Here are some details on my system:

I also post a screenshot that shows that the two monitors are not detected correctly.
I saw some threads about similar problems but none of the solutions seemed to apply. Can someone help me?
