After latest software update to 10.11.3 El Capitain, my screen (Apple LED Cinema) is going blank. This happens especially when I open high def picture or website or when there is a couple of apps open. Even the screen on my macbook pro, goes blank as well. I think this is due to 4K issues update in El Capitain. I never had this problem. Does anyone have same problem ? how can i resolve. Thanks.
MacBook Pro with Retina display, OS X El Capitan (10.11.3)
