View Full Version : External monitor is blue?

Sep 20, 2012, 07:05 AM
I teach High School students in media and because of this it is absolutely essential that I can use a projector with my mac via a dongle from Thunderbolt to VGA. Now I am thinking about upgrading to 10.8 but one of my colleagues just updated and now she is having problems because most of the time the external display only shows a blue screen. Is this a general problem with 10.8 and if so is it fixed in 10.8.2? :confused:
