Hi
Do you have multiple monitors ?

doing

showFullScreen();
qDebug() << geometry();

shows 0,0 and 1920x1080 as expected

i fullscreen i am getting correct but in maximized i want postion.

@satyanarayana143
Do you have a frameless window or something like that?

showMaximized();
qDebug() << geometry();

i get the expected values.

You can try frameGeometry and see if values are more as you expect.
geometry returns the size minus the decorations. ( captions, borders)

not frameless window

@satyanarayana143
well i get perfectly normal values.
Can you show what you do ? (code)

jsulm

@satyanarayana143 Where exactly do you call geometry()? If in constructor of your main window then you should do it after the constructor was executed and the main window is actually being shown.

I've got the same problem using two Dell monitors with Qt 5.11.2 and MSVC2017

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
}

MainWindow::~MainWindow()
{
    delete ui;
}

void MainWindow::on_pushButton_clicked()
{
    qDebug() << "Pos: " << this->pos();
}

Output when maximized:

Pos:  QPoint(-8,-8)
