Dell u3011 intermitently goes black
Hi, I have the latest MBP up to date and I am using a Dell u3011.
The screen works fine until it goes black (the LED remains blue, it does not go to sleep) then either it will come back on after a couple of seconds or it does not come back on at all
Then I have to turn the screen off and on and wake the mac up again.
I am mostly using the Macbook in clamshell mode but I sometime leave it open it behaves the same.
At first I was using the crazy expensive Dual DVI cable from Apple Store, then a friend of mine put me on to MDP to DP port and that worked well for a while but now it's back to the same.
I have good days where I can work for a few hours and bad days where it drives me crazy, doing it up to 10 times in 15 minutes. This is my second monitor and they both had the same issue.
does anyone has the same issue? Rather anyone had the same issue?
your help is appreciated, it seems it happens more frequently as my workload increasesđ .
MacBook Pro with Retina display, Mac OS X (10.7.5)
