Well I see. But I think this behaviour is not new and has something to do with Windows' drivers and hardware detection, plus may be WYSIWYG (if some one remember about that !). I also believe scale display factor (appearing with Vista Aero) has effect. All of this is old and MS will not modify his HAL for so little facts. Think that MS Generic Display Adapter stayed from 2006 to 2018 without anything else new than 800x600 !!!!
