My Macbook Air 11" is displaying with an extended screen but with no external screen connected (like a full screen app display but with no app open)

Today my screen went black but I could connect an external one. After solving this ( shake and SMC reset) my mac had two screens but I don't have any app open and no external screen connected. It is like having two desktops at once, and I can't disable it... Does anyone know how to solve this?

Hello marademacher,

I apologize, I'm a bit unclear on exactly what you are seeing or describing. If you are still having issues with your display after disconnecting the external display and restarting, you may find the troubleshooting steps outlined in the following article helpful:
