I've got my MBP connected to an external monitor (LG 27850-W) and for some reason I can't get my built-in display to turn on. I've tried closing and opening the lid, disconnecting the external and reconnecting, and modifying the display resolution. Nothing seems to bring it back. It just stays off.
Any ideas? My last resort will be to restart the computer, which I would expect to fix the issue. But this is certainly something I've never seen before.
