I’m creating a board game in JavaFx, and it works fine in my desktop PC, with a 1920×1080 screen. When i try to open it in my Laptop (which is 1920×1080 as well, but with the default screen size at 125%, it stops working). The only way to make the app work is to run it on a 1920×1080 screen with default scree size at 100%

I need a way to scale the whole stage to the right resolution

This is my Main.java:

public class Main extends Application {
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws IOException {
        final double WIDTH = Toolkit.getDefaultToolkit().getScreenSize().getWidth();
        final double HEIGHT = Toolkit.getDefaultToolkit().getScreenSize().getHeight();

        Parent board = FXMLLoader.load(getClass().getResource("/board.fxml"));

        Pane innerBoard = ((Pane)board.getChildrenUnmodifiable().get(0));
        Assert.assertCmp(innerBoard.getId(), "BOARD");

        Scene scene = new Scene(board, WIDTH, HEIGHT);

        scene.getStylesheets().add(getClass().getResource("/style.css").toExternalForm());
        primaryStage.setScene(scene);
        primaryStage.setFullScreen(true);
        primaryStage.setResizable(true);
        innerBoard.setVisible(false);
        
        primaryStage.setFullScreenExitHint("");
        primaryStage.show();

        
        innerBoard.setVisible(true);
 
    }

}

This is the FXML:

<Pane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="1080.0" prefWidth="1920.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">
   <children>
      <Pane id="BOARD" fx:id="innerBoard" layoutX="356.0" layoutY="-7.0" style="-fx-background-color: #cfffd1;">
         <children>
            <!-- Lots of children -->
         </children>
      </Pane>
   </children>
</Pane>
