A gender changer is a practical thing to two VGA cable to connect with one another and thus get a longer cable! The quality is actually very good, and you can not go wrong with such a gender changer. In addition, it is not suitable for Dauerinstalationen with cable lengths over 10m (for VA technology or time is already) because the quality just decreases from a cable length of 10m (which in VGA is principally, and is provoked by the Gender Changer) but a SUPER PART!
