How to set up the correct display of screen mirroring in Windows 10?

Question

Windows

I bought a laptop, put 10-ku. I can not set up normal duplication from a laptop to a plasma. I can only expand the screen for now, or turn on the display of a separate screen (when one screen turns off). When screen mirroring is enabled, the same "extension" is obtained. What do you advise?
