Razer Blade 14" Z09-1952 black screen after booting into OS

Hello Dear Razer Community,

I started having issues with my laptop:
Razer Blade (14'') 2016, 256GB, Intel 6700HQ, NVidia GeForce 1060

My laptop freezes when I am using Windows connected to the expansion monitor (DELL U2419H), when I unplug the HDMI cable from my laptop, suddenly the screen goes black with only lights light background.

I tried rebooting the machine, doing everything with BIOS setup but still got the same every time loading to the operating system.
I think the problem is with Nvidia integrated graphics card however I'm not sure about that

Any help would be highly appreciated.
