很多问题和答案都围绕缺少使用javascript处理多个屏幕的选项.出于安全性和技术原因而命名，以解释这种功能的不存在.
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.
另一方面，数千个观点表明对该主题感兴趣，并且人们已经尝试了很多年的变通方法.
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.
因此，我第二次 我想使该过程自动化，以便他们在加载第一个地址后立即在第二个监视器上自动弹出第二个窗口并全屏显示. .这是仅供内部使用的行为. 来自Webmasters.stackexchange问题，我想知道需要做些什么才能获得此功能?
例如是否必须更改HTML标准，例如 2014年以来对代码项目的疑问 -浏览器供应商需要做些什么吗?是否需要添加Javascript，例如我们可以从客户端访问哪些信息?是启动解决方案并开始运行的措施?
E.g. would the HTML standard have to be changed see e.g. question from 2014 on code project - would the browser vendors have to do something? Would there be a need for a Javascript addition to e.g. What information can we access from the client? And what would be the actions to get a solution up and running?
顺便说一句-如果您认为这是题外话，那么我将不得不更改我的问题，以使它不会被关闭.我对此非常认真-我已经看过很多次了.
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.
