Notebook 2009: its original 1440x900 resolution is not available from the Konig electronic box. So you have to get off at a much lower resolution making the low-quality image. This PC can not be used from the box, so it is connected to a former own external display.
New LG HD display dating from 2010, tried and purchased for the occasion, Definition 1920x1080: works very well also from the Konig case, which are connected one desktop PC and a laptop different from the first
Beware VGA cables: it is strongly advised that they are of good quality, especially with adequate ferrites.
