I have a problem with my rMBP (MAC OS:10.8.2) and i'm not sure if it is just an easy fix or if there is a serious hardware issue.


I connect my rMBP to an external projector Hitachi CPX3011 (max resolution 1600x1200) very often for my presentation.


I use a Thunderbolt port to mini display port to VGA adapter to connect my laptop to this projector.


When I plug it into my projector the screen on my rMBP goes black and nothing shows up on the projector.


I try both of the Thunderbolt port, the rMBP switches resolutions and goes back


I called Apple, but the guy just told me to they never encounter this before, (case number 368401545).


Is there something that I am missing here???


Or do you guys think that my Thunderbolt port could be faulty.


By the way, just to be a little more descriptive. When I connect my projector to my rMBP on the port that doesn't work, my screen immediately turns black. I can still see my mouse pointer, but its incredibly HUGE. About the size of a dime.


Please help if you can. I really appreciate it. Check out the video for this problem.
