I did both, as in the following codes, both w1 & w2 are only showing in one screen. Any ideas? Thanks

Qt Code: 
  1. #include <QApplication>
  2. #include <QWidget>
  3.  
  4. int main( int argc, char** argv )
  5. {
  6.   QApplication app( argc, argv );
  7.  
  8.   QWidget w1;
  9.   w1.setWindowTitle( "w1" );
  10.   w1.setGeometry( QRect( 0, 0, 3840, 1200 ) );
  11.   w1.show();
  12.  
  13.   QWidget w2;
  14.   w2.setWindowTitle( "w2" );
  15.   w2.resize( 3840, 1200 );
  16.   w2.move( 0, 0 );
  17.   w2.show();
  18.  
  19.   return app.exec();
  20. }
