I just received an Acer E5-573G laptop, and upon turning it on, the screen did not work. I connected the computer to an external monitor, which worked just fine. When I checked the available displays, the system did not detect the laptop's primary screen. I am at a loss. I have tried reinstalling Windows and updating all of the drivers and the BIOS, all with no luck. Is it simply a faulty screen or is there some software problem I'm not aware of?
