Hi, my laptop display is not working correctly. I have windows 10 64-bit installed and when I boot up, I see the windows logo and loading screen then the display just goes black. Works completely fine when using an external monitor as an only screen. I don't think it's a hardware issue because when I press ctrl+shift+windows+b then the screen flashes a near perfect image. Also I noticed when watching youtube videos in full screen that if most of the output frame is black, the laptop display will show that mostly black frame.
