Is it possible to choose the default screen in a multi monitor configuration?

Thanks for all the help. I found a really simple solution for this problem. Here’s the source code if anyone comes across the same situation :wink:

// Move window to the corresponding monitor
if (GEngine && GEngine->GameViewport) {
	
	int MonitorNumber = 1;
	FParse::Value(FCommandLine::Get(), L"monitor=", MonitorNumber);
	
	FDisplayMetrics Display;
	FDisplayMetrics::GetDisplayMetrics(Display);

	int8 MonitorIndex = MonitorNumber - 1;
	int32 CurrentMonitorWidth = Display.MonitorInfo[MonitorIndex].NativeWidth;
	
	float WidthPosition = (MonitorIndex)*Display.PrimaryDisplayWidth - CurrentMonitorWidth;

	float HeightPosition = 0.0f;

	FVector2D WindowPosition = FVector2D(WidthPosition, 0.f);
	GEngine->GameViewport->GetWindow()->MoveWindowTo(WindowPosition);
}
