Hi all,

I have set up my raspberry pi to use 1280*720 resolution overscan disabled and my console is 1280*720 as set in /boot/config.txt. When i start my application with scene size 1280*720 my scene/stage is scaled by 0.6 (as if 1920*1080 to 1280*720). I can still see my command prompt.

When i run my applcation on 1920*1080 and set the scene size to 1920*1080 everything is fine (except font sizes).

Below my code shortend:

Main class:

    @Override
    public void start(Stage primaryStage) {
        ///redirectOutputToLog();
        rootStage = primaryStage;
        DisplayConfig.setStageProps(rootStage);
        rootStage.addEventHandler(WindowEvent.WINDOW_SHOWN, new EventHandler<WindowEvent>(){
            @Override
            public void handle(WindowEvent window){
                if(preloaderShown==false){
                    mainStage = new MainScene();
                    mainStage.setRoot(rootStage);
                    rootStage.setScene(mainStage.scene());
                }
            }
        });
    }


MainScene class:
public final class MainScene {
    Pane root = new Pane();
    Scene appScene = new Scene(root, DisplayConfig.getScreenWidth(), DisplayConfig.getScreenHeight());
    public MainScene(){
        LOG.debug("Set scene width: {}, height: {}", DisplayConfig.getScreenWidth(), DisplayConfig.getScreenHeight());
    }

    public final Scene scene(){
        return appScene;
    }

}


DisplayConfig class:

public final class DisplayConfig {
    static ObservableList<Screen> screens = Screen.getScreens();

    static final Rectangle2D primaryScreenBounds = Screen.getPrimary().getBounds();
    
    static double curScreenWidth = primaryScreenBounds.getWidth();
    static double curScreenHeight = primaryScreenBounds.getHeight();

    public static void setStageProps(Stage primaryStage){
        //// Here we will be checking if there is a second screen, and if there is force the app to go there
        primaryStage.initStyle(StageStyle.UNDECORATED);
        LOG.debug("Got {} screens", screens.size());
        if(screens.size()>1){
            for (Screen curScreen : screens) {
                LOG.debug("Current screen check is primary: {}", curScreen.equals(Screen.getPrimary()));
                if(!curScreen.equals(Screen.getPrimary())) {
                    LOG.debug("Going secondary screen");
                    Rectangle2D newScreenBounds = curScreen.getBounds();
                    screenPosX = newScreenBounds.getMinX();
                    screenPosY = newScreenBounds.getMinY();
                    curScreenWidth = newScreenBounds.getWidth();
                    curScreenHeight = newScreenBounds.getHeight();
                    ratioX = (1/defaultWidth) * curScreenWidth;
                    ratioY = (1/defaultHeight) * curScreenHeight;
                    primaryStage.setWidth(curScreenWidth);
                    primaryStage.setHeight(curScreenHeight);
                    primaryStage.setX(screenPosX);
                    primaryStage.setY(screenPosY);
                    primaryStage.toFront();
                    break;
                }
            }
        } else {
            LOG.debug("Staying primary");
            ratioX = (1/defaultWidth) * curScreenWidth;
            ratioY = (1/defaultHeight) * curScreenHeight;
            primaryStage.setFullScreen(true);
        }
        LOG.debug("Screen properties: posX: {}, posY: {}, width: {}, height: {}, ratioX: {}, ratioY: {}", screenPosX, screenPosY, curScreenWidth,curScreenHeight, ratioX,ratioY);
    }
}

My debug logging shows the correct screen sizes:

---

The scaling ratios are because my application is primarely designed for 1920*1080, and some panes needs te be resized (which works correct in the view).

- I have already tried to remove the stage.fullscreen(true) and set the stage width and height, the combination of the two
- stage.sizetoscene() and even set my scene and stage dimensions to 1920*1080.

There is no location in my code which scales the scene, but only sets the scene width and height.

Best regards,
John.
