I have a solution for the 1080p Inspiron 7537's dark screen after booting up which works most of the time. You can only install OS X and preform the first setup process with the boot flag GraphicsEnabler=No. After that, when the display turns black while booting up, wait a few seconds and press Ctrl+Shift+power button, you know if you were successful if the backlight goes off. Now do something with the touchpad to turn the screen back again and it should show your desktop. (Please note that it only works if you enabled automatic login to a user account.)
