I tried the following steps listed here:
- Delete /Library/Preferences/com.apple.windowserver.plist
- Delete ~/Library/Preferences/ByHost/com.apple.windowserver*.plist
- Shutdown OSX
- Startup, immediately press and hold the P and R keys while holding down the option (⌥) and command (⌘) keys before the gray boot screen appears, which resets the NVRAM
- You may have to reset your display preferences (resolution) once you login
