I have a 2012 Macbook Pro 2.3 GHz i7 with 16GB of RAM plugged into a AOC 24" LED display via a VGA/Thunderbolt adapter...both items are less then a year old. Everything was working great then all the sudden my external display started to just go to sleep at random times. It then couldn't be recognized by my Mac even after unplugging and plugging back in. It will eventually just turn back on or I have to log in/out or shut down to get it back. Not sure what is going on here. Very anoying problem...does anybody know what is going on here?


MacBook Pro, OS X Mountain Lion (10.8.2), 16GB RAM, 120GB SSD.
