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?

You want to have a multi display android config. cf:

Configuring Display Settings

source TileUtils.java

source SuggestionParser.java

  • I don't want a multi display I just want to have a single display on external monitor with Specific key combination to project since my laptop's screen is damaged. – User5 Dec 26 '16 at 15:30
  • The android feature is named multi display, but you can configure only one of course – Rémi Cohen-Scali Dec 26 '16 at 15:34
  • Agreed... but how? – User5 Dec 26 '16 at 15:35
  • Of course all this is reserved for very advanced users, but it is possible to map your specific projection keys (from your laptop keyboard) on intents for configuring your android. All documentation I mentioned allows to configure the android part. You still need to catch the keycodes for your <fn> keys and use them. Perhaps first try with some easier keys (as 'a', 'b', etc). – Rémi Cohen-Scali Dec 26 '16 at 15:38
  • Fn+ F7 works for Windows but any other Fn + any other key does nothing for android. I can't even toggle bluetooth On and Off by Key combination. – User5 Dec 26 '16 at 15:40

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.
