    External Display Gone Black
    I have a Gateway monitor. IT's connected to my Macbook pro. It used to work fine and then I put the Macbook to sleep and now there is only a black screen for the secondary (Gateway) monitor. The monitor is not the issue (I troubleshooted it with an old laptop). The MAcbook is detecting the secondary display but there is no picture. Any ideas?

    Try resetting the System Management Controller (SMC) for your MacBook Pro and at the same time power off the external monitor and let it set for a bit. Follow the instructions at this LINK.
