My extended monitor is set as primary but Kodi only shows on laptop

Up to now I have been using a Samsung Syncmaster 932 BW as an extended monitor as the primary with no problems.
All of a sudden in monitor preferences it goes into laptop (HP Ultrabook 8460p) as my primary. When I reset it to the external monitor as primary it goes back to laptop as primary.
UPDATE: 5/23/16 Now everthing is back to nomal. My external monitor is set as primary on monitor preferences everything works just fine…except when I load Kodi. Kodi will only show on my laptop and does not show on my external monitor.
