ViewSonic VA2012W and MacBook Pro Retina 15.2 compatability

in Genius Bar edited June 2015



I have just bought a new MacBook Pro Retina 15.2 and wish to use my ViewSonic VA2012w hi resolution monitor with it.


Have connected it from the VGA with a cable switch into hdmi on to the MacBook Pro. It doesn't work and is only flickering on the MacBook without any image on the ViewSonic.


Am I doing something wrong?

Do I need to download any special driver to get it to work ?
