    Please guys, help me, I am desperate...

    I brought last year a Mac Mini 2011 (the base model with Intel 3000 HD). Yesterday I brought a Dell U2713H.

    1) The monitor alone with the mac mini works 100% OK no mater the cable i use.

    2) To my surprise, when i connect a second 1080p or lower res monitor to the mac mini the Dell monitor goes black for a few seconds out of the blue! Then after say a second or two the image returns. It feels like the cable loses the connection for a moment.

    The issue appears ONLY when i connect the Dell monitor with the display port to mini dp cable and ONLY when the resolution is 1440p. If I set the resolution on the Dell monitor to 1080p it works OK.


    Tell me your opinion guys, the Mac Mini, the Monitor or the cable is to blame?

    How much RAM do you have? Per :

    No idea if this is related to your issue, but if you don't have 8GB might be a good time to upgrade RAM.
