I have installed Windows as well as android x86 on my laptop. Everything was just fine until the LCD of my Laptop was not broken. Now with broken screen I use Specific key combination to project my screen to an external monitor. This feature works fine with Windows but the key-combination does not work for android x86. Monitor does not even detect a signal from laptop. Is there any trick to project the screen in android with parent screen broken?
Just find your grub configuration file of android-x86 operating system and add
video=LVDS-1:d to the end.
This will enable external monitor connected through HDMI port and disable primary monitor after boot. You can also add command for resolution which suits your external monitor but this is not necessary.
