window.open() on a multi-monitor/dual-monitor system - where does window pop up?

Question

When using javascript window.open() on a multi-monitor system, how do you control which monitor, or where in the display space the popup opens? It seems out of control to me

Answer 1

None of the above solutions are works correctly. in terms of exact Center,

I tried this , It works fine for me in chrome and firefox

var sY = screenY;
        if (sY < 0) {
            sY = 0;
        }
        var totalScreenWidth = (screenX + window.outerWidth + sY);
        if (totalScreenWidth > screen.width) {
            totalScreenWidth = totalScreenWidth / 2;
        } else {
            totalScreenWidth = 0;
        }
        windowobj.moveTo(totalScreenWidth + ((screen.width - h) / 2), ((screen.height - h) / 2));

But this also have issue if the second monitors browser is viewed half in first and another half in second.
