title: What is the unit of selenium's Dimension(1200,600)?
body: <p>I am automating an application where it is necessary to for the application to have 1200x600 pixel size of the browser. I am using a code like below to maximize(I don't want to use <code>dirver.manage().maximize()</code> code it has some problem with application).
  Here the below is my code</p>
  
  <pre><code>Dimension d = new Dimension(1200,600);
  //Resize the current window to the given dimension
  driver.manage().window().setSize(d);
  </code></pre>
  
  <p>But still, the application is not compatible with this size. So can somebody tell what is the unit used int this 1200 and 600 in Dimention() constructor?
  It is fine if some gives the equivalency value 1200x600 pixel value in Dimenstion(xxx,xxx).</p>
  
  <p>Note: using google-chrome 65.x,windows 10.</p>
