ScreenDetails: currentscreenchange event

The currentscreenchange event of the ScreenDetails interface is fired when the ScreenDetails.currentScreen changes in one of the following ways:

• The current screen changes to a different screen, i.e., the current browser window is moved to a different screen.
• One or more of the following properties change on the current screen:
  • width
  • height
  • availWidth
  • availHeight
  • colorDepth
  • orientation
• One or more of the following values change:
  • The screen's position ((x,y) coordinates of the top-left corner) inside the OS virtual screen arrangement, relative to the multi-screen origin
  • The screen's available position ((x,y) coordinates of the top-left corner) inside the OS virtual screen arrangement, relative to the multi-screen origin. This is equal to the screen position, plus the width/height of any OS UI elements drawn on the top-left of the screen — windows cannot be placed in those areas
  • devicePixelRatio
  • label
  • The screen's designation as primary or secondary (see isPrimary)
  • The screen's designation as internal or external (see isInternal)
