The Screen interface has been roaming the praries since when Netscape 
Navigator ruled the World Wide Web (geez!). Although Screen is specified 
in the CSSOM View Module [1], I think it is useless nowadays because our 
working canvas is the browser's viewport, and we can rely on CSS media 
queries (no JavaScript involved) if we need to adjust the design to the 
device's screen resolution,  [2]

According to the CSSOM View Module, the width / height attribute must 
return the width / height of the output device in CSS pixels.

Due to the lack of other good / reliable resources, MDN is a bless. But 
as MDN is a Wiki, everyone can contribute to it or spoil the party.
