Apalis-iMX8_Reference-Multimedia-Image-Tezi_5.7.0-devel-20230613121500+build.0

And Bellow code::

    int width[3], height[3];
        int num_of_screens;

        // check multiple screens
        QList <QScreen*> screens = QGuiApplication::screens();
        num_of_screens = screens.size();
        qDebug() << "the number of display: " << num_of_screens;

        QCursor::setPos(10,10);

        for (int i = 0; i < screens.size(); i++) {
            width[i] = screens[i]->geometry().width();
            height[i] = screens[i]->geometry().height();
        auto name = screens[i]->name();
            qDebug() << "[" << i << " " << name << "]" <<  \
            width[i] << " x " << height[i];
        }

And The result of it::
