title: What needs to be done to make multiple screen support for Javascript happen?
body: <p>As I was wondering about the multi-monitor/screen support of javascript i found the follwing stackexchange questions relevant for the topic:</p>

  <p>Quite a few of the questions and answers revolve around the missing option of handling multiple screens with javascript. Security and technical reasons are named to account for the non-existence of such a feature.</p>
  
  <p>On the other hand a few thousand views show that there is interest in the topic and people have tried work-arounds for many years.</p>
  
  <p>So i second <strong><em>I want to automate that process so as soon as they load the first address, a second window automatically pops up on the second monitor and fullscreens itself. This is internal only and will be expected behaviour.</em></strong> from the webmasters.stackexchange question and <strong>i would like to know what needs to be done to get this feature?</strong></p>
  
  <p>E.g. would the HTML standard have to be changed see e.g. <a href="https://www.codeproject.com/Questions/774588/Intresting-question-Multi-Monotor-support-in-HTML" rel="nofollow noreferrer">question from 2014 on code project</a> - would the browser vendors have to do something? Would there be a need for a Javascript addition to e.g. <a href="https://stackoverflow.com/questions/8180296/what-information-can-we-access-from-the-client">What information can we access from the client?</a> And what would be the actions to get a solution up and running?</p>
  
  <p>And by the way - if you think this is off-topic how would I have to change my question so that it won't be closed. I am very serious about this - there is a need behind this that I have seen quite a few times already.</p>
