title: How to access screen display’s DPI settings via javascript?
body: <p>Is there a way to access the screen display's DPI settings in a Javascript function?</p>
  
  <p>I am trying to position a HTML panel on the page and when the user's DPI is set to large (120), it throws the position off.  I need to be able to know what the DPI is so I can adjust the position accordingly.</p>
