I have a Dell Latitude E6520 with i7 Sandy Bridge Intel HD3000 Samsung SSD EVO 850 Pro.  El Capitan 10.11.6 was installed and working at 1920x1080x32 up until the latest security update 2016-003.  System restarted and the LCD stopped working.  I can boot into safe mode and LCD will work, but in normal multi user or single user modes, only HDMI to monitor works.  LCD will remain black.  On boot up in Clover with verbose, the LCD screen will go off with HDMI working.
