Extending screens
 

I was able to get everything connected and semi working. I have selected to extend displays but they are only somewhat extended. I can move the mouse across both screens but I can also click the windows button on both screens. Its as if they are both extended and individual screens at the same time. Windows 10.

Hello,

That's correct, the default behaviour of Windows is to add the taskbar.
You can edit your Windows settings to only show one taskbar on the primary display.

Kind regards,
Alban
