;''Description''

: Returns the width of the window in pixels.  This value is affected by the UI's scale.

: Also note that the return value will not match the screen resolution chosen from the Video Options menu, but will instead represent a dimension with the same aspect ratio.  For example, the following code...
 DEFAULT_CHAT_FRAME:AddMessage( ( GetScreenWidth() * UIParent:GetEffectiveScale() ).."x"..( GetScreenHeight() * UIParent:GetEffectiveScale() ) );
: ...will print "960x768" for the actual screen resolution "1280x1024".  Both of these dimensions share a 5:4 aspect ratio.
