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.
