Change orientation in androidx86 How can I fully rotate my screen and not only resize it like in the picture?

In already tried several rotation apps in the play store. I tried via root shell the commands: wm size, settings put system accelerometer_rotation 0 and settings put system user_rotation 0 both are working fine on my phone, but not on my tablet.
You should try some rotation control app from play store, like Rotation Control which can rotate the screen in any direction you want (like reverse portrait)
     But you should also note that it's not possible with every app, because maybe the layout is not provided or the layout is forced to be in portrait mode, in that case no app can help you.
    There ain't much apps available specifically for xxhdpi &amp; xxxhdpi screens and so you're not left with much choice but to work with the way it is....
