Mac Mini Monitor Won't Wake Up ( Fixed )
Fixed!!! Hey I found a pretty long discussion about having issues with this... I just bought a Mac Mini brought it home and it did the same thing many people have been talking about that the HMDI will not wake up the monitor without powering the monitor off and back on. Lastnight I did the OSX update and everything is working great now!!!!
Here how you get the the update: Go to System Preferences / App Store and click the check now button. Once you see the OSX update click the update button.
Good luck!!! Worked for me and I hope it works for you...
