SplashScreen shown on wrong monitor, scaling is incorrect

I am using two displays on my Windows 10, a laptop (1920x1200) and an external monitor (3840x2160) with extended dual display setup.

When using Qt Creator on my monitor and launch the attached example app, the splashscreen is shown in my laptop's display, while the application itself is launched correctly on my monitor. Also, the splashscreen is not sized correctly. I only see the upper left corner of the image (assuming the image is scaled correctly), but the splashscreen itself is too small and it is not on the center of the screen.
