Q: MBPr 15" no video signal with thunderbold

Hi,

 

I have a MacBook Pro (Retina, 15-inch, Mid 2015) with a Dell P2415Q connected via a mini-display port.

It was working fine since 3 months until this morning.


In the preferences the Dell Monitor is no more mentioned.

In the "System Profiler" I can see the 2 thunderbold port.

I have a message on the Dell screen that mention there is no signal.

If I remove the cable it say that there is no cable.


If I use an HDMI cable instead of the display port it's working fine.


I have tried to shutdown and restart several time, without success.

I have tried to reset the PRAM without success.


Any ideas please ? What can I try ?


Thanks a lot.
