I belive it is a plasma problem involving  Nvidia Twinview.
I tried setting it manualy in xrandr (even if aparently kde display configuration detect and can define position and orientation of both monitors), but still KDE can't notice it need to put a plasma screen on left monitor.

xrandr give this:

Comment 2 Nate Graham 2018-06-08 18:37:21 UTC
Hello!

This bug report was filed for KDE Plasma 4, which reached end-of-support status in August 2015. KDE Plasma 5's desktop shell has been almost completely rewritten for better performance and usability, so it is likely that this bug has already been resolved in Plasma 5.

Accordingly, we hope you understand why we must close this bug report. If the issue described  here is still present in KDE Plasma 5.12 or later, please feel free to open a new ticket in the "plasmashell" product after reading https://community.kde.org/Get_Involved/Bug_Reporting

If you would like to get involved in KDE's bug triaging effort so that future mass bug closes like this are less likely, please read https://community.kde.org/Get_Involved#Bug_Triaging

Thanks for your understanding!
