Black Screen after 15 sec on Mac Mini Display Port
I have a LED cinema display 24" and I decided to plug it in my new mid 2014 MBP15" retina and its not detected for video.
Sound is working fine, iSight too but not screen.
I decide to do the PRAM and SMC reset.Nothing
Then Updated the firmware... follow all the discussions...
nothing can make it work.
So i decided to plug it back on my Mac mini but BIMMM it stays dark too.
After reboot the screens turns on Apple logo and loading bar from yosemite then the screens turns off after 15-20sec
the mac mini is an old model and is not thunderbolt i can't copy/paste the setup as i can't see it with the screen
I'm wondering if there is anything I can do with it ? As im not under warranty anymore...
