I have an acer nitro 5 laptop and the built in screen is not working properly. The majority of the screen is black, only the top part is showing images.
If I use it on my Ubuntu instead of Windows and set it to 60Hz, it works almost perfecty, with minor flaws that are hard to notice.
I want to know if it is the internal cable that is problematic or it is the screen itself. How can i check it?
