Display issue with intel 4600 driver

Hi, I am new to the forum. I have an issue with my Asus G750 screen after replacing my crack screen (first image). The issue is whenever I tried enabling intel 4600 in graphic adapter the situation in (second image) happens, it goes back to normal if I disable it. With the intel driver disable, nvidia control panel shows that there is no display connected to it. With that I can't even do the simplest gpu task. i.e playing games at its minimum setting also causes stutter. I had tried reinstalling both nvidia and intel driver and clearing the registry. Really hope to get help. Thanks.

You need the igpu to use the dgpu because optimus.

 

Connect a external monitor and change the settings.

I tried. It did not work. I am starting to think is it the igpu has been shorted when my screen crack. Does that kind of things happen?

Is whenever I enable the igpu, the problem occurred.
