In a multi-monitor display environment, how do I tell Selenium which display to open a new window in?

Question

Sorry if this has been asked and answered. I did a search but came up empty.

Answer 1

I have 2 1920x1080 monitors, I move the browser window to the 2nd monitor and maximize it there.

1. Get screen resolution

   java.awt.Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
   double width = screenSize.getWidth();
   double height = screenSize.getHeight();
   

2. Move browser to second monitor and maximize

   if (width <= 1920) {
       Point point = new Point(width, 0);
       driver.manage().window().setPosition(point);
       driver.manage().window().maximize();
   }
   

3. If your resolution is wider than a typical monitor, open the browser in a more realistic resolution (this is optional, but I recommend it)

   else 
   
   {
       Point point = new Point(0, 0);
       driver.manage().window().setPosition(point);
   
       Dimension targetWindowSize = new Dimension(1920, 1080);
       driver.manage().window().setSize(targetWindowSize);
   }
   

Answer 2

I noticed that for me its always opening in the primary monitor. So I changed the primary display from OSX display arrangement options window.

Answer 3

There's actually a fairly easy way to do this. There's a method called 'set_window_position' which accepts negative values. So I wanted the browser to open on my left screen, so a simple negative 1000px pixels dragged it in enough for the maximize_window to pick the left screen.

driver.set_window_position(-1000, 0)
driver.maximize_window()

So depending on the screen sizes and where you want it to go, make some calculations and just drag it there!

Answer 4

In case the monitor where you want to open a browser windows is to the left of the monitor with IDE, try negative values. In Java:

WebDriver driver = new FirefoxDriver();
driver.manage().window().setPosition(new Point(-1500, 0));

Answer 5

Just put the Mac "Menu Bar" on the monitor where you want the browser to open up. That sets the default monitor.
