God they almost make it impossible to see what exact version you have.
Maybe you can look in device manager or dxidag under display tab.
According to MSI site.
15.6" FHD (1920x1080), IPS-Level
15.6" UHD (3840x2160), IPS-Level
4k will have a UHD screen rather then a EFD. Maybe we can see the screens model some where? So we know for a fact what we are dealing with and where to go from there.
