the desktop screen is devided into 3 parts, 2 black on each side of the main screen.
It sounds more like playing a movie in fullscreen 4:3 instead of widescreen 16:9, rather than being divided into 3 parts. That's probably a video driver issue.
See if there is an updated one for Win10 from Windows Update, or you might even have to try an old one with compatibility mode. I see both Intel and AMD drivers listed for that model, but only up to Windows 7.

As for the airplane mode, let us know what you already tried.
