Based on
[GetMonitorInfo](https://learn.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-getmonitorinfoa)
API doc, it seems fine to use this API to query monitor info for both primary
and non-primary monitors but I'm not sure why original code used
`SystemParametersInfo()` specifically instead of `GetMonitorInfo()` for
primary monitor.
In case the screen insets need to be calculated differently for primary and
non-primary then MonitorInfo (`miInfo.dwFlag`) can be used to check if it is
primary monitor or not, instead of relying on screen number as follows
MONITORINFO *miInfo = AwtWin32GraphicsDevice::GetMonitorInfo(screenNum);
if (MONITORINFOF_PRIMARY & miInfo ->dwFlags) {
// calculate screen insets for Primary monitor
}
else {
//calculate screen insets for NON-Primary monitor
}
