Two of these dead in different ways, but the same time?
I have two 24" ACDs connected to my MacBook Pro retina. Everything was working great until this morning, they went to sleep and never came back.
One display flickers on for a second, then goes black. The audio and USB hub are working.
The other display does nothing at all. The MacBook doesn't even acknowledge it being unplugged and reconnected.
I have trouble believing that both of these displays suffered different failures at the exact same moment.
Are there common troubleshooting steps after I open them up?
