Turns out I was suffering of a rare problem affecting the SMC of my macbook.
I installed the version 10.8.3 and now I'll see if the problem is fixed.
The display is working OK since 2days. Thanks for your help ^_^
I tried right now and nothing happened. Still not working when I connect it.
I'll call my nearest Apple Store tomorrow morning and I'll keep you updated.
I'm pretty sure tomorrow morning the monitor will work normally.
Thank you
It's good to see that I'm not alone.
I add few details from my experience:
- I have the lastest ML running on a MBP 15 retina.
- The issue occurs when I leave the computer in stop for 2hours or more. Unplugging and plugging doesn't help and I need to wait many hours with the monitor...
