4K Playing Movies Kodi switches to portrait mode

Hi Guys,

Just installed Pimax on my new laptop: MSI GS73VR 7RF with Nvidia 1060 GTX. (i downloaded the latest Nvidia driver)
When playing a movie, kodi switches into portait mode instead of landscape.
I tried to switch back to landscape with windows settings, but everytime when i start movie kodi switches it back to portrait again.
When I unplug HDMI, Kodi plays normal in landscape mode.

When i use VLC to play, the image turns upside down??? (180°)

Please, someone knows the answer?
Thanks in advance.
